189-652: Berlin Tempelhof Airport ( German : Flughafen Berlin-Tempelhof ) ( IATA : THF , ICAO : EDDI ) was one of the first airports in Berlin , Germany. Situated in the south-central Berlin borough of Tempelhof-Schöneberg , the airport ceased operating in 2008 amid controversy, leaving Tegel and Schönefeld as the two main airports serving the city for another twelve years until both were replaced by Berlin Brandenburg Airport in 2020. Tempelhof

378-574: A British United 200 series operating a trooping flight under contract to the UK Ministry of Defence diverted from Gatow. German language German (German: Deutsch , pronounced [dɔʏtʃ] ) is a West Germanic language in the Indo-European language family , mainly spoken in Western and Central Europe . It is the most spoken native language within

567-465: A de facto official language of Namibia after the end of German colonial rule alongside English and Afrikaans , and had de jure co-official status from 1984 until its independence from South Africa in 1990. However, the Namibian government perceived Afrikaans and German as symbols of apartheid and colonialism, and decided English would be the sole official language upon independence, stating that it

756-459: A freighter airplane by installing a front cargo door, as it was initially thought that it would eventually be superseded by supersonic transports . Boeing introduced the -200 in 1971, with uprated engines for a heavier maximum takeoff weight (MTOW) of 833,000 pounds (378 t) from the initial 735,000 pounds (333 t), increasing the maximum range from 4,620 to 6,560 nautical miles [nmi] (8,560 to 12,150 km; 5,320 to 7,550 mi). It

945-402: A second language , and 75–100   million as a foreign language . This would imply the existence of approximately 175–220   million German speakers worldwide. German sociolinguist Ulrich Ammon estimated a number of 289 million German foreign language speakers without clarifying the criteria by which he classified a speaker. As of 2012 , about 90   million people, or 16% of

1134-612: A "commonly used" language and the Pan South African Language Board is obligated to promote and ensure respect for it. Cameroon was also a colony of the German Empire from the same period (1884 to 1916). However, German was replaced by French and English, the languages of the two successor colonial powers, after its loss in World War I . Nevertheless, since the 21st century, German has become

1323-610: A $ 569 million post-tax charge against its fourth-quarter 2015 profits. At the end of 2015, the company had 20 orders outstanding. On January 29, 2016, Boeing announced that it had begun the preliminary work on the modifications to a commercial 747-8 for the next Air Force One presidential aircraft, then expected to be operational by 2020. On July 12, 2016, Boeing announced that it had finalized an order from Volga-Dnepr Group for 20 747-8 freighters, valued at $ 7.58 billion (~$ 9.44 billion in 2023) at list prices. Four aircraft were delivered beginning in 2012. Volga-Dnepr Group

1512-459: A 5,000-nautical-mile (9,300 km; 5,800 mi) range with a typical 452-passenger payload, and an increased MTOW of 750,000 lb (340 t) was offered. The first -100B order, one aircraft for Iran Air , was announced on June 1, 1978. This version first flew on June 20, 1979, received FAA certification on August 1, 1979, and was delivered the next day. Nine -100Bs were built, one for Iran Air and eight for Saudi Arabian Airlines . Unlike

1701-590: A 520,000-pound (240 t) MTOW and Pratt & Whitney JT9D -7A engines derated to 43,000 pounds-force (190 kN) of thrust. Following the -100SR, Boeing produced the -100BSR, a 747SR variant with increased takeoff weight capability. Debuting in 1978, the -100BSR also incorporated structural modifications for a high cycle-to-flying hour ratio; a related standard -100B model debuted in 1979. The -100BSR first flew on November 3, 1978, with first delivery to All Nippon Airways (ANA) on December 21, 1978. A total of 20 -100BSRs were produced for ANA and JAL. The -100BSR had

1890-548: A 600,000 pounds (270 t) MTOW and was powered by the same JT9D-7A or General Electric CF6 -45 engines used on the -100SR. ANA operated this variant on domestic Japanese routes with 455 or 456 seats until retiring its last aircraft in March 2006. In 1986, two -100BSR SUD models, featuring the stretched upper deck (SUD) of the -300, were produced for JAL. The type's maiden flight occurred on February 26, 1986, with FAA certification and first delivery on March 24, 1986. JAL operated

2079-430: A forerunner of today's modern airports, the building was designed with many unique features, including giant arc-shaped aircraft hangars . Although under construction for more than ten years, it was never finished because of World War II . For passengers and freight, the 1927-built terminal stayed in use until 24 April 1945. The building complex was designed to resemble an eagle in flight with semicircular hangars forming

2268-452: A fully occupied 747. Nonetheless, many flag-carriers purchased the 747 due to its prestige "even if it made no sense economically" to operate. During the 1970s and 1980s, over 30 regularly scheduled 747s could often be seen at John F. Kennedy International Airport . The recession of 1969–1970 , despite having been characterized as relatively mild, greatly affected Boeing. For the year and a half after September 1970, it only sold two 747s in

2457-428: A good spread of support on the ground and safety in case of tire blow-outs. The main gear are redundant so that landing can be performed on two opposing landing gears if the others are not functioning properly. The 747 also has split control surfaces and was designed with sophisticated triple-slotted flaps that minimize landing speeds and allow the 747 to use standard-length runways. For transportation of spare engines,

2646-559: A greater need for regularity in written conventions. While the major changes of the MHG period were socio-cultural, High German was still undergoing significant linguistic changes in syntax, phonetics, and morphology as well (e.g. diphthongization of certain vowel sounds: hus (OHG & MHG "house") → haus (regionally in later MHG)→ Haus (NHG), and weakening of unstressed short vowels to schwa [ə]: taga (OHG "days")→ tage (MHG)). A great wealth of texts survives from

2835-492: A growing presence at Tempelhof. (In addition to continuing AOA's original, multistop Berlin – New York route and dedicated internal German services connecting Berlin with Frankfurt, Hamburg and Düsseldorf , between 1955 and 1959, Pan Am commenced regular, year-round scheduled services to Cologne , Stuttgart , Hanover , Munich and Nuremberg from Tempelhof.) Pan Am's initial equipment for its new Berlin operation were unpressurised , 60-seat Douglas DC-4s , widely available at

3024-405: A high-capacity airliner with enough range to cover Pan Am's New York–Middle Eastern routes and Iran Air's planned Tehran–New York route. The Tehran–New York route, when launched, was the longest non-stop commercial flight in the world. The 747SP is 48 feet 4 inches (14.73 m) shorter than the 747-100. Fuselage sections were eliminated fore and aft of the wing, and the center section of

3213-437: A higher maximum takeoff weight (MTOW) variant, and the -100SR (Short Range), with higher passenger capacity. Increased maximum takeoff weight allows aircraft to carry more fuel and have longer range. The -200 model followed in 1971, featuring more powerful engines and a higher MTOW. Passenger, freighter and combination passenger-freighter versions of the -200 were produced. The shortened 747SP (special performance) with

3402-549: A higher-density seating arrangement than competing airlines' aircraft. (Pan Am's DC-6Bs were originally configured in a 76-seat, all- economy layout. The subsequent introduction of subsidies for all scheduled internal German services from/to West Berlin resulted in steady network growth as well as service frequency and passenger load increases. To cope with the sharply higher traffic volumes, aircraft seat densities were increased twice – initially to 84 and subsequently 87 seats.) This fleet eventually grew to 17 aircraft, which gave Pan Am

3591-452: A jet 2 + 1 ⁄ 2 times its size, to reduce its seat cost by 30%. In 1965, Joe Sutter left the 737 development program to design the 747. In April 1966, Pan Am ordered 25 Boeing 747-100 aircraft, and in late 1966, Pratt & Whitney agreed to develop the JT9D engine, a high-bypass turbofan . On September 30, 1968, the first 747 was rolled out of the custom-built Everett Plant ,

3780-403: A long "spine" running the length of the aircraft with the wing spar passing through it, while Boeing blended the two, with a longer pod that ran from just behind the nose to just behind the wing. In 1965, Lockheed's aircraft design and General Electric's engine design were selected for the new C-5 Galaxy transport, which was the largest military aircraft in the world at the time. Boeing carried

3969-410: A longer range was also developed, and entered service in 1976. The 747 line was further developed with the launch of the 747-300 on June 11, 1980, followed by interest from Swissair a month later and the go-ahead for the project. The 300 series resulted from Boeing studies to increase the seating capacity of the 747, during which modifications such as fuselage plugs and extending the upper deck over

4158-481: A more spacious 66-seat single-class seating arrangement, soon replaced the older series 701 aircraft. The greater range and higher cruising speed of the 802 series enabled BEA to inaugurate a non-stop London Heathrow – Berlin Tempelhof service on 1 November 1965. this was the only non-stop international scheduled air service from Tempelhof On 19 November 1959, a Pan Am DC-4 became the first aircraft to operate

4347-458: A native tongue today, mostly descendants of German colonial settlers . The period of German colonialism in Namibia also led to the evolution of a Standard German-based pidgin language called " Namibian Black German ", which became a second language for parts of the indigenous population. Although it is nearly extinct today, some older Namibians still have some knowledge of it. German remained

4536-421: A new jet airliner 2 + 1 ⁄ 2 times size of the 707, with a 30% lower cost per unit of passenger-distance and the capability to offer mass air travel on international routes. Trippe also thought that airport congestion could be addressed by a larger new aircraft. In 1965, Joe Sutter was transferred from Boeing's 737 development team to manage the design studies for the new airliner, already assigned

4725-696: A popular foreign language among pupils and students, with 300,000 people learning or speaking German in Cameroon in 2010 and over 230,000 in 2020. Today Cameroon is one of the African countries outside Namibia with the highest number of people learning German. In the United States, German is the fifth most spoken language in terms of native and second language speakers after English, Spanish , French , and Chinese (with figures for Cantonese and Mandarin combined), with over 1 million total speakers. In

4914-462: A range of 4,620 nautical miles (8,556 km), was the original variant launched in 1966. The 747-200 soon followed, with its launch in 1968. The 747-300 was launched in 1980 and was followed by the 747-400 in 1985. Ultimately, the 747-8 was announced in 2005. Several versions of each variant have been produced, and many of the early variants were in production simultaneously. The International Civil Aviation Organization (ICAO) classifies variants using

5103-483: A result, the surviving texts are written in highly disparate regional dialects and exhibit significant Latin influence, particularly in vocabulary. At this point monasteries, where most written works were produced, were dominated by Latin, and German saw only occasional use in official and ecclesiastical writing. While there is no complete agreement over the dates of the Middle High German (MHG) period, it

5292-559: A scheduled all-cargo service from West Berlin. This service linked Tempelhof with Rhein-Main Airport once-nightly, all year round. On 2 January 1960, Air France , which had served Düsseldorf, Frankfurt, Munich, Nuremberg and its main base at Paris Le Bourget / Orly during the previous decade with DC-4, Sud-Est Languedoc and Lockheed Constellation / Super Constellation piston-engined equipment, shifted its entire Berlin operation to Tegel because Tempelhof's runways were too short to permit

5481-447: A shortened code formed by combining the model number and the variant designator (e.g. "B741" for all -100 models). The first 747-100s were built with six upper deck windows (three per side) to accommodate upstairs lounge areas. Later, as airlines began to use the upper deck for premium passenger seating instead of lounge space, Boeing offered an upper deck with ten windows on either side as an option. Some early -100s were retrofitted with

5670-496: A single airline before or since. Ultimately, the high-winged CX-HLS Boeing design was not used for the 747, although technologies developed for their bid had an influence. The original design included a full-length double-deck fuselage with eight-across seating and two aisles on the lower deck and seven-across seating and two aisles on the upper deck. However, concern over evacuation routes and limited cargo-carrying capability caused this idea to be scrapped in early 1966 in favor of

5859-435: A special flight from Frankfurt to Berlin to demonstrate to the airline the 727 's ability to operate from Tempelhof's short runways. Pan Am indicated its intention to place an order for six 727s for its Berlin operation, as a result of the aircraft using only half the 5,900 ft (1,800 m) runway during landing. 26 October 1965 marked British Aircraft Corporation 's new One-Eleven jet's first arrival at Tempelhof when

6048-439: A steady increase in the airline's passenger loads. (This included an ex- Transair Vickers Viscount 700 belonging to its newly formed independent rival British United Airways , which was damaged beyond repair on 30 October 1961 at Frankfurt Rhein-Main Airport at the end of a passenger flight that had originated at Tempelhof.) By 1954, a year that saw 671,555 passengers pass through the airport, Tempelhof had established itself as

6237-635: A subsequently built runway containing perforated steel matting began to crumble under the weight of the USAF's C-54 Skymasters . Hence, American engineers built a new 6,000 ft (1,800 m) runway at Tempelhof between July and September 1948 and another between September and October 1948 to accommodate the expanding requirements of the airlift. The old airport terminal of 1927 was demolished in 1948 in order to create additional space for unloading more planes. The last airlift transport touched down at Tempelhof on 30 September 1949. Tempelhof also became famous as

6426-405: A test aircraft was flown to Renton to have test equipment removed and a cabin installed. Pilot Ralph C. Cokely undershot the airport's short runway and the 747's right, outer landing gear was torn off and two engine nacelles were damaged. However, these difficulties did not prevent Boeing from taking a test aircraft to the 28th Paris Air Show in mid-1969, where it was displayed to the public for

6615-544: A total of 3,746 people have died. In 1963, the United States Air Force started a series of study projects on a very large strategic transport aircraft. Although the C-141 Starlifter was being introduced, officials believed that a much larger and more capable aircraft was needed, especially to carry cargo that would not fit in any existing aircraft. These studies led to initial requirements for

6804-796: A united city of Berlin to the unified German government. The U.S. Army closed its Berlin Army Aviation Detachment at TCA in August 1994, ending a 49-year American military presence in Berlin. In 1951 the US Army stationed an aviation element of the 6. Infantry Brigade-( 6th Infantry Regiment ?) with three Hiller OH-23A Raven helicopters at Tempelhof. Over the years it became known as the Berlin Brigade Aviation Detachment (BBDE Avn.Det.). The Hiller OH-23A

6993-448: A wider single deck design. The cockpit was therefore placed on a shortened upper deck so that a freight-loading door could be included in the nose cone; this design feature produced the 747's distinctive "hump". In early models, what to do with the small space in the pod behind the cockpit was not clear, and this was initially specified as a "lounge" area with no permanent seating. (A different configuration that had been considered to keep

7182-601: Is a recognized minority language in the following countries: In France, the High German varieties of Alsatian and Moselle Franconian are identified as " regional languages ", but the European Charter for Regional or Minority Languages of 1998 has not yet been ratified by the government. Namibia also was a colony of the German Empire, from 1884 to 1915. About 30,000 people still speak German as

7371-612: Is also notable for its broad spectrum of dialects , with many varieties existing in Europe and other parts of the world. Some of these non-standard varieties have become recognized and protected by regional or national governments. Since 2004, heads of state of the German-speaking countries have met every year, and the Council for German Orthography has been the main international body regulating German orthography . German

7560-558: Is an Indo-European language that belongs to the West Germanic group of the Germanic languages . The Germanic languages are traditionally subdivided into three branches: North Germanic , East Germanic , and West Germanic . The first of these branches survives in modern Danish , Swedish , Norwegian , Faroese , and Icelandic , all of which are descended from Old Norse . The East Germanic languages are now extinct, and Gothic

7749-478: Is called the "German Sprachraum ". German is the official language of the following countries: German is a co-official language of the following countries: Although expulsions and (forced) assimilation after the two World wars greatly diminished them, minority communities of mostly bilingual German native speakers exist in areas both adjacent to and detached from the Sprachraum. Within Europe, German

7938-430: Is complicated by the existence of several varieties whose status as separate "languages" or "dialects" is disputed for political and linguistic reasons, including quantitatively strong varieties like certain forms of Alemannic and Low German . With the inclusion or exclusion of certain varieties, it is estimated that approximately 90–95 million people speak German as a first language , 10–25   million speak it as

8127-535: Is generally seen as ending when the 1346–53 Black Death decimated Europe's population. Modern High German begins with the Early New High German (ENHG) period, which Wilhelm Scherer dates 1350–1650, terminating with the end of the Thirty Years' War . This period saw the further displacement of Latin by German as the primary language of courtly proceedings and, increasingly, of literature in

8316-611: Is generally seen as lasting from 1050 to 1350. This was a period of significant expansion of the geographical territory occupied by Germanic tribes, and consequently of the number of German speakers. Whereas during the Old High German period the Germanic tribes extended only as far east as the Elbe and Saale rivers, the MHG period saw a number of these tribes expanding beyond this eastern boundary into Slavic territory (known as

8505-565: Is less closely related to languages based on Low Franconian dialects (e.g., Dutch and Afrikaans), Low German or Low Saxon dialects (spoken in northern Germany and southern Denmark ), neither of which underwent the High German consonant shift. As has been noted, the former of these dialect types is Istvaeonic and the latter Ingvaeonic, whereas the High German dialects are all Irminonic; the differences between these languages and standard German are therefore considerable. Also related to German are

8694-435: Is one of the major languages of the world . German is the second-most widely spoken Germanic language , after English, both as a first and as a second language . German is also widely taught as a foreign language , especially in continental Europe (where it is the third most taught foreign language after English and French), and in the United States. Overall, German is the fourth most commonly learned second language, and

8883-597: Is one of the three biggest newspapers in Namibia and the only German-language daily in Africa. An estimated 12,000 people speak German or a German variety as a first language in South Africa, mostly originating from different waves of immigration during the 19th and 20th centuries. One of the largest communities consists of the speakers of "Nataler Deutsch", a variety of Low German concentrated in and around Wartburg . The South African constitution identifies German as

9072-401: Is partly derived from Latin and Greek , along with fewer words borrowed from French and Modern English . English, however, is the main source of more recent loanwords . German is a pluricentric language ; the three standardized variants are German , Austrian , and Swiss Standard German . Standard German is sometimes called High German , which refers to its regional origin. German

9261-525: Is the Sachsenspiegel , the first book of laws written in Middle Low German ( c.  1220 ). The abundance and especially the secular character of the literature of the MHG period demonstrate the beginnings of a standardized written form of German, as well as the desire of poets and authors to be understood by individuals on supra-dialectal terms. The Middle High German period

9450-578: Is the only language in this branch which survives in written texts. The West Germanic languages, however, have undergone extensive dialectal subdivision and are now represented in modern languages such as English, German, Dutch , Yiddish , Afrikaans , and others. Within the West Germanic language dialect continuum, the Benrath and Uerdingen lines (running through Düsseldorf - Benrath and Krefeld - Uerdingen , respectively) serve to distinguish

9639-513: Is the parent of three major Russian air-freight carriers – Volga-Dnepr Airlines , AirBridgeCargo Airlines and Atran Airlines . The new 747-8 freighters would replace AirBridgeCargo's current 747-400 aircraft and expand the airline's fleet and will be acquired through a mix of direct purchases and leasing over the next six years, Boeing said. On July 27, 2016, in its quarterly report to the Securities and Exchange Commission , Boeing discussed

9828-485: Is understood in all areas where German is spoken. Approximate distribution of native German speakers (assuming a rounded total of 95 million) worldwide: As a result of the German diaspora , as well as the popularity of German taught as a foreign language , the geographical distribution of German speakers (or "Germanophones") spans all inhabited continents. However, an exact, global number of native German speakers

10017-689: The Ostsiedlung ). With the increasing wealth and geographic spread of the Germanic groups came greater use of German in the courts of nobles as the standard language of official proceedings and literature. A clear example of this is the mittelhochdeutsche Dichtersprache employed in the Hohenstaufen court in Swabia as a standardized supra-dialectal written language. While these efforts were still regionally bound, German began to be used in place of Latin for certain official purposes, leading to

10206-463: The 767 and Airbus A300 / A310 twinjets ). Having tried replacing coach seats on its 747s with piano bars in an attempt to attract more customers, American Airlines eventually relegated its 747s to cargo service and in 1983 exchanged them with Pan Am for smaller aircraft; Delta Air Lines also removed its 747s from service after several years. Later, Delta acquired 747s again in 2008 as part of its merger with Northwest Airlines , although it retired

10395-639: The Alamanni , Bavarian, and Thuringian groups, all belonging to the Elbe Germanic group ( Irminones ), which had settled in what is now southern-central Germany and Austria between the second and sixth centuries, during the great migration. In general, the surviving texts of Old High German (OHG) show a wide range of dialectal diversity with very little written uniformity. The early written tradition of OHG survived mostly through monasteries and scriptoria as local translations of Latin originals; as

10584-515: The Berlin Senate and the city's Technical University as well as Berliner Flugring, a local package tour operator that began as a consortium of 70 West Berlin travel agents arranging IT flights to holiday resorts in Europe. By 1964, BEA operated up to 20,000 flights each year from and to Berlin. These represented approximately half of the airline's total yearly flights to/from Germany and generated profits of £ 1 million per year. 1964

10773-517: The Boeing 747-400 fleet in December 2017. International flights bypassing traditional hub airports and landing at smaller cities became more common throughout the 1980s, thus eroding the 747's original market. Many international carriers continued to use the 747 on Pacific routes. In Japan, 747s on domestic routes were configured to carry nearly the maximum passenger capacity. The 747-100 with

Overseas, sizeable communities of German-speakers are found in Brazil ( Blumenau and Pomerode ), South Africa ( Kroondal ), Namibia , among others, some communities have decidedly Austrian German or Swiss German characters (e.g. Pozuzo , Peru). German

11151-537: The Early Middle Ages . German is an inflected language , with four cases for nouns, pronouns, and adjectives (nominative, accusative, genitive, dative); three genders (masculine, feminine, neuter) and two numbers (singular, plural). It has strong and weak verbs . The majority of its vocabulary derives from the ancient Germanic branch of the Indo-European language family, while a smaller share

11340-480: The European Union 's population, spoke German as their mother tongue, making it the second most widely spoken language on the continent after Russian and the second biggest language in terms of overall speakers (after English), as well as the most spoken native language. The area in central Europe where the majority of the population speaks German as a first language and has German as a (co-)official language

11529-671: The European Union . It is the most widely spoken and official (or co-official) language in Germany , Austria , Switzerland , Liechtenstein , and the Italian autonomous province of South Tyrol . It is also an official language of Luxembourg , Belgium and the Italian autonomous region of Friuli-Venezia Giulia , as well as a recognized national language in Namibia . There are also notable German-speaking communities in France ( Alsace ),

11718-522: The German states . While these states were still part of the Holy Roman Empire , and far from any form of unification, the desire for a cohesive written language that would be understandable across the many German-speaking principalities and kingdoms was stronger than ever. As a spoken language German remained highly fractured throughout this period, with a vast number of often mutually incomprehensible regional dialects being spoken throughout

11907-746: The Holy Roman Emperor Maximilian I , and the other being Meißner Deutsch , used in the Electorate of Saxony in the Duchy of Saxe-Wittenberg . Alongside these courtly written standards, the invention of the printing press led to the development of a number of printers' languages ( Druckersprachen ) aimed at making printed material readable and understandable across as many diverse dialects of German as possible. The greater ease of production and increased availability of written texts brought about increased standardisation in

12096-666: The Old High German language in several Elder Futhark inscriptions from as early as the sixth century AD (such as the Pforzen buckle ), the Old High German period is generally seen as beginning with the Abrogans (written c.  765–775 ), a Latin-German glossary supplying over 3,000 Old High German words with their Latin equivalents. After the Abrogans , the first coherent works written in Old High German appear in

German is used in a wide variety of spheres throughout the country, especially in business, tourism, and public signage, as well as in education, churches (most notably the German-speaking Evangelical Lutheran Church in Namibia (GELK) ), other cultural spheres such as music, and media (such as German language radio programs by the Namibian Broadcasting Corporation ). The Allgemeine Zeitung

Punctuation and compound spelling (joined or isolated compounds) were not standardized in the process. The Deutsche Bühnensprache ( lit.   ' German stage language ' ) by Theodor Siebs had established conventions for German pronunciation in theatres , three years earlier; however, this

12663-513: The Upper German dialects spoken in the southern German-speaking countries , such as Swiss German ( Alemannic dialects ) and the various Germanic dialects spoken in the French region of Grand Est , such as Alsatian (mainly Alemannic, but also Central–and   Upper Franconian dialects) and Lorraine Franconian (Central Franconian). After these High German dialects, standard German

12852-469: The pagan Germanic tradition. Of particular interest to scholars, however, has been the Hildebrandslied , a secular epic poem telling the tale of an estranged father and son unknowingly meeting each other in battle. Linguistically, this text is highly interesting due to the mixed use of Old Saxon and Old High German dialects in its composition. The written works of this period stem mainly from

13230-506: The -100BSR SUD with 563 seats on domestic routes until their retirement in the third quarter of 2006. While only two -100BSR SUDs were produced, in theory, standard -100Bs can be modified to the SUD certification. Overall, 29 Boeing 747SRs were built. The 747-100B model was developed from the -100SR, using its stronger airframe and landing gear design. The type had an increased fuel capacity of 48,070 US gal (182,000 L), allowing for

13419-495: The 1927-built terminal remained closed to all civil aviation, and all civilian aircraft movements to and from Berlin were transferred to an airfield in Rangsdorf until 7 March 1940, when the 1927 terminal was reopened and civil aviation continued until 24 April 1945. From January 1940 until early 1944, Weser Flugzeugbau assembled Junkers Ju 87 "Stuka" dive bombers; thereafter, it assembled Focke-Wulf Fw 190 fighter planes in

13608-418: The 1950s, 1960s and early 1970s, protecting passengers from the elements. Tempelhof Airport's main building was once among the twenty largest buildings on earth, but it also formerly contained the world's smallest duty-free shop . Tempelhof Airport closed all operations on 30 October 2008, despite the efforts of some protesters to prevent the closure. A non-binding referendum was held on 27 April 2008 against

13797-487: The 300 series were produced. In 1985, development of the longer range 747-400 began. The variant had a new glass cockpit , which allowed for a cockpit crew of two instead of three, new engines, lighter construction materials, and a redesigned interior. Development costs soared, and production delays occurred as new technologies were incorporated at the request of airlines. Insufficient workforce experience and reliance on overtime contributed to early production problems on

13986-519: The 747 Advanced that were eventually adopted. Similar in nature to the 747-X, the stretched 747 Advanced used technology from the 787 to modernize the design and its systems. The 747 remained the largest passenger airliner in service until the Airbus A380 began airline service in 2007. On November 14, 2005, Boeing announced it was launching the 747 Advanced as the Boeing 747-8 . The last 747-400s were completed in 2009. As of 2011 , most orders of

14175-549: The 747 can accommodate a non-functioning fifth-pod engine under the aircraft's port wing between the inner functioning engine and the fuselage. The fifth engine mount point was also used by Virgin Orbit 's LauncherOne program to carry an orbital-class rocket to cruise altitude where it was deployed. After the aircraft's introduction with Pan Am in 1970, other airlines that had bought the 747 to stay competitive began to put their own 747s into service. Boeing estimated that half of

14364-468: The 747 had been a major challenge, and building its assembly plant was also a huge undertaking. Boeing president William M. Allen asked Malcolm T. Stamper, then head of the company's turbine division, to oversee construction of the Everett factory and to start production of the 747. To level the site, more than four million cubic yards (three million cubic meters) of earth had to be moved. Time

14553-472: The 747-400, several stretching schemes for the 747 were proposed. Boeing announced the larger 747-500X and -600X preliminary designs in 1996. The new variants would have cost more than US$ 5 billion to develop, and interest was not sufficient to launch the program. In 2000, Boeing offered the more modest 747X and 747X stretch derivatives as alternatives to the Airbus A38X . However, the 747X family

14742-472: The 747-400. The -400 entered service in 1989. In 1991, a record-breaking 1,087 passengers were flown in a 747 during a covert operation to airlift Ethiopian Jews to Israel . Generally, the 747-400 held between 416 and 524 passengers. The 747 remained the heaviest commercial aircraft in regular service until the debut of the Antonov An-124 Ruslan in 1982; variants of the 747-400 surpassed

14931-562: The 747-8 were for the freighter variant. On February 8, 2010, the 747-8 Freighter made its maiden flight . The first delivery of the 747-8 went to Cargolux in 2011. The first 747-8 Intercontinental passenger variant was delivered to Lufthansa on May 5, 2012. The 1,500th Boeing 747 was delivered in June 2014 to Lufthansa. In January 2016, Boeing stated it was reducing 747-8 production to six per year beginning in September 2016, incurring

15120-459: The An-124's weight in 2000. The Antonov An-225 Mriya cargo transport , which debuted in 1988, remains the world's largest aircraft by several measures (including the most accepted measures of maximum takeoff weight and length); one aircraft has been completed and was in service until 2022. The Scaled Composites Stratolaunch is currently the largest aircraft by wingspan . After the arrival of

15309-472: The Berlin city centre and quickly became one of the world's busiest airports. Tempelhof saw its greatest pre-war days during 1938–1939, when up to 52 foreign and 40 domestic flights arrived and departed daily from the old terminal while the new one was still under construction. The new air terminal was designed as headquarters for Deutsche Luft Hansa (moved in 1938), the German national airline at that time. As

15498-526: The CX-Heavy Logistics System (CX-HLS) in March 1964 for an aircraft with a load capacity of 180,000 pounds (81.6 t) and a speed of Mach 0.75 (430 kn; 800 km/h), and an unrefueled range of 5,000 nautical miles (9,300 km; 5,800 mi) with a payload of 115,000 pounds (52.2 t). The payload bay had to be 17 feet (5.18 m) wide by 13.5 feet (4.11 m) high and 100 feet (30 m) long with access through doors at

15687-723: The Empire. Its use indicated that the speaker was a merchant or someone from an urban area, regardless of nationality. Prague (German: Prag ) and Budapest ( Buda , German: Ofen ), to name two examples, were gradually Germanized in the years after their incorporation into the Habsburg domain; others, like Pressburg ( Pozsony , now Bratislava), were originally settled during the Habsburg period and were primarily German at that time. Prague, Budapest, Bratislava, and cities like Zagreb (German: Agram ) or Ljubljana (German: Laibach ), contained significant German minorities. In

15876-748: The Frisian languages— North Frisian (spoken in Nordfriesland ), Saterland Frisian (spoken in Saterland ), and West Frisian (spoken in Friesland )—as well as the Anglic languages of English and Scots. These Anglo-Frisian dialects did not take part in the High German consonant shift, and the Anglic languages also adopted much vocabulary from both Old Norse and the Norman language . The history of

16065-483: The German language begins with the High German consonant shift during the Migration Period , which separated Old High German dialects from Old Saxon . This sound shift involved a drastic change in the pronunciation of both voiced and voiceless stop consonants ( b , d , g , and p , t , k , respectively). The primary effects of the shift were the following below. While there is written evidence of

16254-451: The German states; the invention of the printing press c.  1440 and the publication of Luther's vernacular translation of the Bible in 1534, however, had an immense effect on standardizing German as a supra-dialectal written language. The ENHG period saw the rise of several important cross-regional forms of chancery German, one being gemeine tiutsch , used in the court of

16443-681: The Germanic dialects that were affected by the High German consonant shift (south of Benrath) from those that were not (north of Uerdingen). The various regional dialects spoken south of these lines are grouped as High German dialects, while those spoken to the north comprise the Low German and Low Franconian dialects. As members of the West Germanic language family, High German, Low German, and Low Franconian have been proposed to be further distinguished historically as Irminonic , Ingvaeonic , and Istvaeonic , respectively. This classification indicates their historical descent from dialects spoken by

16632-655: The Irminones (also known as the Elbe group), Ingvaeones (or North Sea Germanic group), and Istvaeones (or Weser–Rhine group). Standard German is based on a combination of Thuringian - Upper Saxon and Upper Franconian dialects, which are Central German and Upper German dialects belonging to the High German dialect group. German is therefore closely related to the other languages based on High German dialects, such as Luxembourgish (based on Central Franconian dialects ) and Yiddish . Also closely related to Standard German are

16821-518: The MHG period. Significantly, these texts include a number of impressive secular works, such as the Nibelungenlied , an epic poem telling the story of the dragon -slayer Siegfried ( c.  thirteenth century ), and the Iwein , an Arthurian verse poem by Hartmann von Aue ( c.  1203 ), lyric poems , and courtly romances such as Parzival and Tristan . Also noteworthy

17010-702: The US, the UK and other countries as well as local outbound tourists to the emerging holiday resorts in the Mediterranean . London Gatwick -based UK independent Overseas Aviation (CI) was among the first airlines the Allied Air Attachés in Bonn licensed to operate a series of regular charter flights from West Berlin. It used Vikings and Argonauts on these services, which operated from Tempelhof under contract to

17199-408: The aircraft's upper deck; instead of using a conventional slide, volunteer passengers escaped by using a harness attached to a reel. Tests also involved taxiing such a large aircraft. Boeing built an unusual training device known as "Waddell's Wagon" (named for a 747 test pilot, Jack Waddell) that consisted of a mock-up cockpit mounted on the roof of a truck. While the first 747s were still being built,

17388-462: The airframe, along with General Electric and Pratt & Whitney for the engines. The airframe proposals shared several features. As the CX-HLS needed to be able to be loaded from the front, a door had to be included where the cockpit usually was. All of the companies solved this problem by moving the cockpit above the cargo area; Douglas had a small "pod" just forward and above the wing, Lockheed used

17577-717: The airline's Berlin routes the most profitable in its worldwide scheduled network. Following the completion of the Berlin Wall on 13 August 1961, the West German government introduced a route-specific subsidy of up to 20% for all internal German scheduled air services from and to West Berlin to help the airlines cope with the resulting falloff in traffic and maintain an economically viable operation on these lifeline routes. These came into effect on 1 March 1962 for all tickets sold in Germany, including Berlin. (To qualify for

17766-462: The airline's last-ever flight to depart Tempelhof left for Madrid , but was later shot down over Southern Germany . Tempelhof's German commander, Oberst Rudolf Böttger, refused to carry out orders to blow up the base, choosing instead to kill himself. Soviet forces took Tempelhof in the Battle of Berlin on 28 and 29 April 1945 in the closing days of the war in Europe. Soviet forces combed through

17955-406: The airport buildings preserved. In September 2015, in the midst of the 2015 European migrant crisis , it was announced by the Berlin state government that Tempelhof would become an 'emergency refugee shelter', holding at least 1,200 people in two former hangars. The site of the airport was originally Knights Templar land in medieval Berlin, and from this beginning came the name Tempelhof . Later,

18144-411: The airport. The runways are not comparatively long, either - versus Brandenburg's 3600m and 4000m runways which can easily handle intercontinental airliners like the Boeing 747 , Tempelhof has two runways at 2094m (09R/27L) and 1840m (09L/27R), which can, at most, handle Boeing 757 and Airbus A320 -size aircraft. Other possible uses for Tempelhof have been discussed, and many people are trying to keep

18333-471: The annual "Day of Open House" of the United States Air Force (USAF) at the airport. The Galaxy had its first appearance at Tempelhof on 17 September 1971, when an aircraft of the USAF's 436th Military Airlift Wing flew in from Dover Air Force Base in Delaware , United States, to participate in that year's "Day of Open House" static exhibition. These events respectively marked the debut at Tempelhof of

18522-550: The biggest aircraft fleet among the three main scheduled operators flying from West Berlin. It furthermore enabled it to compensate for the DC-6 's lack of sophistication with higher frequencies than its competitors, thereby attaining a higher market share (60%) and capturing a greater share of the lucrative business travel market than its rivals. During that period, Pan Am moreover achieved an ultra short-haul load factor of 70% on its eight scheduled internal routes from Berlin, making

18711-403: The bird's spread wings. A 1.6-kilometre-long (1 mi) hangar roof was to have been laid in tiers to form a stadium for spectators at air and ground demonstrations. Norman Foster called Tempelhof "one of the really great buildings of the modern age". Fearing Allied bombing of airports, all German civil aviation was halted on 2 September 1939, but gradually restarted from 1 November. However,

18900-732: The black market. In accordance with the Yalta agreements , Zentralflughafen Berlin-Tempelhof was turned over to the United States Army 2nd Armored Division on 2 July 1945 by the Soviet Union as part of the American occupation sector of Berlin. This agreement was later formalised by the August 1945 Potsdam Agreement , which formally divided Berlin into four occupation sectors. The 852nd Engineer Aviation Battalion arrived at Tempelhof (Code Number R-95) on 10 July 1945 and conducted

19089-462: The ceremonial 747 contract-signing banquet in Seattle on Boeing's 50th Anniversary, Juan Trippe predicted that the 747 would be "…a great weapon for peace, competing with intercontinental missiles for mankind's destiny". As launch customer, and because of its early involvement before placing a formal order, Pan Am was able to influence the design and development of the 747 to an extent unmatched by

19278-592: The city of Berlin. As the Cold War intensified in the late 1950s and 1960s, access problems to West Berlin , both by land and air, continued to cause tension. Throughout the Cold War years, Tempelhof was the main terminal for American military transport aircraft accessing West Berlin. In 1969 one of the pilots during the Berlin Airlift, and the original Candy Bomber , Gail Halvorsen , returned to Berlin as

19467-652: The city prior to the construction of the infamous Berlin Wall . This operation was also known as the Little Berlin Airlift . One of these airlines, UK independent Dan-Air Services would subsequently play an important role in developing commercial air services from Tegel for a quarter century. During the early-to-mid-1950s, BEA leased in aircraft that were bigger than its Tempelhof-based fleet of DC-3/ Pionair , Viking and Elizabethan piston -engined airliners from other operators to boost capacity, following

19656-563: The city were three 20 mi (32 km)-wide air corridors across the Soviet Zone of Occupation . Faced with the choice of abandoning the city or attempting to supply its inhabitants with the necessities of life by air, the Western Powers chose the latter course. Operation Vittles , as the airlift was unofficially named, began on 26 June when USAF Douglas C-47 Skytrains carried 80 tons of food into Tempelhof, far less than

19845-639: The commander of Tempelhof airbase. With the fall of the Berlin Wall and the reunification of Germany , the presence of American forces in Berlin ended. The USAF 7350th Air Base Group at Tempelhof was inactivated in June 1993. In July 1994, with President Clinton in attendance, the British, French, and American air and land forces in Berlin were deactivated in a ceremony on the Four Ring Parade field at McNair Barracks. The Western Allies returned

20034-471: The concept but was committed to developing the engine for the C-5 Galaxy and did not enter the commercial market until later. Pratt & Whitney was also working on the same principle and, by late 1966, Boeing, Pan Am and Pratt & Whitney agreed to develop a new engine, designated the JT9D to power the 747. The project was designed with a new methodology called fault tree analysis , which allowed

20223-430: The development of non-local forms of language and exposed all speakers to forms of German from outside their own area. With Luther's rendering of the Bible in the vernacular, German asserted itself against the dominance of Latin as a legitimate language for courtly, literary, and now ecclesiastical subject-matter. His Bible was ubiquitous in the German states: nearly every household possessed a copy. Nevertheless, even with

20412-475: The device allowed pilots to practice taxi maneuvers from a high upper-deck position. In 1968, the program cost was US$ 1 billion (equivalent to $ 6.7 billion in 2023 dollars). On September 30, 1968, the first 747 was rolled out of the Everett assembly building before the world's press and representatives of the 26 airlines that had ordered the airliner. Over the following months, preparations were made for

20601-456: The dialect so as to make the work as natural and accessible to German speakers as possible. Copies of Luther's Bible featured a long list of glosses for each region, translating words which were unknown in the region into the regional dialect. Luther said the following concerning his translation method: One who would talk German does not ask the Latin how he shall do it; he must ask the mother in

20790-412: The early 747 sales were to airlines desiring the aircraft's long range rather than its payload capacity. While the 747 had the lowest potential operating cost per seat, this could only be achieved when the aircraft was fully loaded; costs per seat increased rapidly as occupancy declined. A moderately loaded 747, one with only 70 percent of its seats occupied, used more than 95 percent of the fuel needed by

20979-519: The eastern provinces of Banat , Bukovina , and Transylvania (German: Banat, Buchenland, Siebenbürgen ), German was the predominant language not only in the larger towns—like Temeschburg ( Timișoara ), Hermannstadt ( Sibiu ), and Kronstadt ( Brașov )—but also in many smaller localities in the surrounding areas. In 1901, the Second Orthographic Conference ended with a (nearly) complete standardization of

21168-490: The effects of a failure of a single part to be studied to determine its impact on other systems. To address concerns about safety and flyability, the 747's design included structural redundancy, redundant hydraulic systems, quadruple main landing gear and dual control surfaces. Additionally, some of the most advanced high-lift devices used in the industry were included in the new design, to allow it to operate from existing airports. These included Krueger flaps running almost

21357-425: The empennage. As Boeing did not have a plant large enough to assemble the giant airliner, they chose to build a new plant. The company considered locations in about 50 cities, and eventually decided to build the new plant some 30 miles (50 km) north of Seattle on a site adjoining a military base at Paine Field near Everett , Washington. It bought the 780-acre (320 ha) site in June 1966. Developing

21546-552: The engines had been installed, the finished aircraft were flown out. The Luftwaffe did not use Tempelhof as a military airfield during World War II, except for occasional emergency landings by fighter aircraft. On 21 April 1945, Deutsche Luft Hansa operated its last scheduled flights, and over the coming days laid on additional non-scheduled flights from Johannisthal Air Field which stopped over at Tempelhof to take on freight en route to Travemünde and Munich , where Luft Hansa had relocated its headquarters. Two days later, on 23 April,

21735-581: The entire duration of the Berlin Blockade (26 June 1948 – 12 May 1949). Following the end of the Berlin Blockade, AOA launched additional dedicated scheduled services linking Tempelhof with Hamburg Fuhlsbüttel and Düsseldorf Lohausen from 6 March and 1 June 1950 respectively. On 25 September 1950, Pan Am acquired AOA from American Airlines. This merger resulted in Pan Am establishing

21924-403: The entire length of the fuselage were rejected. The first 747-300, completed in 1983, included a stretched upper deck, increased cruise speed, and increased seating capacity. The -300 variant was previously designated 747SUD for stretched upper deck, then 747-200 SUD, followed by 747EUD, before the 747-300 designation was used. Passenger, short range and combination freighter-passenger versions of

22113-409: The entire length of the wing's leading edge, as well as complex three-part slotted flaps along the trailing edge of the wing. The wing's complex three-part flaps increase wing area by 21% and lift by 90% when fully deployed compared to their non-deployed configuration. Boeing agreed to deliver the first 747 to Pan Am by the end of 1969. The delivery date left 28 months to design the aircraft, which

22302-499: The estimated 4,500 tons of food, coal and other essential supplies needed daily to maintain a minimum level of existence. But this force was soon augmented by United States Navy and Royal Air Force cargo aircraft, as well as British European Airways (BEA) and many of Britain 's fledgling wholly privately owned, independent airlines. The last included Freddie Laker 's Air Charter , Eagle Aviation and Skyways . On 15 October 1948, to promote increased safety and cooperation between

22491-486: The evacuation of 560 volunteers from a cabin mock-up via the aircraft's emergency chutes. The first full-scale evacuation took two and a half minutes instead of the maximum of 90 seconds mandated by the Federal Aviation Administration (FAA), and several volunteers were injured. Subsequent test evacuations achieved the 90-second goal but caused more injuries. Most problematic was evacuation from

22680-504: The events of an emergency if they cannot do so through the cabin. The 747's maximum takeoff weight ranges from 735,000 pounds (333 t) for the -100 to 970,000 pounds (440 t) for the -8. Its range has increased from 5,300 nautical miles (9,800 km; 6,100 mi) on the -100 to 8,000 nautical miles (15,000 km; 9,200 mi) on the -8I. The 747 has redundant structures along with four redundant hydraulic systems and four main landing gears each with four wheels; these provide

22869-433: The first flight, which took place on February 9, 1969, with test pilots Jack Waddell and Brien Wygle at the controls and Jess Wallick at the flight engineer's station. Despite a minor problem with one of the flaps, the flight confirmed that the 747 handled extremely well. The 747 was found to be largely immune to " Dutch roll ", a phenomenon that had been a major hazard to the early swept-wing jets. During later stages of

23058-410: The first time. Finally, in December 1969, the 747 received its FAA airworthiness certificate , clearing it for introduction into service. The huge cost of developing the 747 and building the Everett factory meant that Boeing had to borrow heavily from a banking syndicate. During the final months before delivery of the first aircraft, the company had to repeatedly request additional funding to complete

23247-411: The flight by more than six hours to the following day when Clipper Victor (registration N736PA) was used. The 747 enjoyed a fairly smooth introduction into service, overcoming concerns that some airports would not be able to accommodate an aircraft that large. Although technical problems occurred, they were relatively minor and quickly solved. After the initial 747-100, Boeing developed the -100B ,

23436-431: The flight deck out of the way for freight loading had the pilots below the passengers, and was dubbed the "anteater".) One of the principal technologies that enabled an aircraft as large as the 747 to be drawn up was the high-bypass turbofan engine . This engine technology was thought to be capable of delivering double the power of the earlier turbojets while consuming one-third less fuel. General Electric had pioneered

23625-541: The flight test program, flutter testing showed that the wings suffered oscillation under certain conditions. This difficulty was partly solved by reducing the stiffness of some wing components. However, a particularly severe high-speed flutter problem was solved only by inserting depleted uranium counterweights as ballast in the outboard engine nacelles of the early 747s. This measure caused some concern when these aircraft crashed, for example El Al Flight 1862 at Amsterdam in 1992 with 622 pounds (282 kg) of uranium in

23814-500: The front and rear. The desire to keep the number of engines to four required new engine designs with greatly increased power and better fuel economy. In May 1964, airframe proposals arrived from Boeing, Douglas , General Dynamics , Lockheed , and Martin Marietta ; engine proposals were submitted by General Electric , Curtiss-Wright , and Pratt & Whitney . Boeing, Douglas, and Lockheed were given additional study contracts for

24003-562: The heaviest versions of the A340 until surpassing the 747 in size with the A380 , delivered between 2007 and 2021. Freighter variants of the 747 remain popular with cargo airlines. The final 747 was delivered to Atlas Air in January 2023 after a 54-year production run, with 1,574 aircraft built. As of December 2023 , 64 Boeing 747s (4.1%) have been lost in accidents and incidents , in which

24192-435: The home, the children on the streets, the common man in the market-place and note carefully how they talk, then translate accordingly. They will then understand what is said to them because it is German. When Christ says ' ex abundantia cordis os loquitur ,' I would translate, if I followed the papists, aus dem Überflusz des Herzens redet der Mund . But tell me is this talking German? What German understands such stuff? No,

24381-426: The impending closure but failed due to low voter turnout. The former airfield has subsequently been used as a recreational space known as Tempelhofer Feld . In September 2015, it was announced that Tempelhof would also become an emergency refugee camp . Tempelhof was often called the "City Airport". In its later years, it mostly had commuter flights to other parts of Germany and neighbouring countries; but it had in

24570-481: The influence of Luther's Bible as an unofficial written standard, a widely accepted standard for written German did not appear until the middle of the eighteenth century. German was the language of commerce and government in the Habsburg Empire , which encompassed a large area of Central and Eastern Europe . Until the mid-nineteenth century, it was essentially the language of townspeople throughout most of

24759-488: The introduction of the Sud-Aviation Caravelle , their new short-haul jet , with a viable payload . (Air France's Caravelle IIIs lacked thrust reversers that would have permitted them to land safely on Tempelhof's short runways with a full commercial payload.) On 1 March 1960, Pan Am launched its second dedicated scheduled all-cargo flight from Berlin, linking Tempelhof with Hamburg Fuhlsbüttel. 1960

24948-411: The largest aircraft in commercial airline service at the time and the then-largest aircraft overall. Tempelhof, compared to Brandenburg Airport and Tegel Airport , wasn't a particularly large airport. The layout of the airport was relatively simple - two parallel runways oriented east–west (09/27 L/R), with a single oval taxiway around the airport, with the main terminal on the north-western segment of

25137-478: The largest concentrations of German speakers are in the states of Rio Grande do Sul (where Riograndenser Hunsrückisch developed), Santa Catarina , and Espírito Santo . Boeing 747 The Boeing 747 is a long-range wide-body airliner designed and manufactured by Boeing Commercial Airplanes in the United States between 1968 and 2023. After the introduction of the 707 in October 1958, Pan Am wanted

25326-406: The location of Operation Little Vittles: the dropping of candy to children living near the airport. The original Candy Bomber , Gail Halvorsen noticed children lingering near the fence line of the airport and wanted to share something with them. He eventually started dropping candy by parachute just before landing. His efforts were expanded by other pilots and eventually became a part of legend in

25515-466: The main deck, the cockpit creates a hump. This raised cockpit allows front loading of cargo on freight variants. The upper deck behind the cockpit provides space for a lounge and/or extra seating. The "stretched upper deck" became available as an alternative on the 747-100B variant and later as standard beginning on the 747-300. The upper deck was stretched more on the 747-8. The 747 cockpit roof section also has an escape hatch from which crew can exit during

25704-549: The model number 747. Sutter began a design study with Pan Am and other airlines to better understand their requirements. At the time, many thought that long-range subsonic airliners would eventually be superseded by supersonic transport aircraft. Boeing responded by designing the 747 so it could be adapted easily to carry freight and remain in production even if sales of the passenger version declined. In April 1966, Pan Am ordered 25 Boeing 747-100 aircraft for US$ 525 million (equivalent to $ 3.8 billion in 2023 dollars). During

25893-402: The mother in the home and the plain man would say, Wesz das Herz voll ist, des gehet der Mund über . Luther's translation of the Bible into High German was also decisive for the German language and its evolution from Early New High German to modern Standard German. The publication of Luther's Bible was a decisive moment in the spread of literacy in early modern Germany , and promoted

26082-417: The new configuration. The -100 was equipped with Pratt & Whitney JT9D -3A engines. No freighter version of this model was developed, but many 747-100s were converted into freighters as 747-100(SF). The first 747-100(SF) was delivered to Flying Tiger Line in 1974. A total of 168 747-100s were built; 167 were delivered to customers, while Boeing kept the prototype, City of Everett . In 1972, its unit cost

26271-460: The new terminal into a furnace and making it impossible to enter for several weeks. The raging inferno led the Soviet commander to order the lower levels to be flooded with water. With no functioning water supply in war-torn Berlin, this was only possible because the new terminal, which had suffered only slight war damage, had its own electricity and groundwater utility with underground reservoirs under

26460-512: The new, wholly privately owned UK independent airlines and US supplemental carriers started regular air services to Tempelhof from the UK, the US and West Germany . These airlines initially carried members of the UK and US armed forces stationed in Berlin and their dependants as well as essential raw materials, finished goods manufactured in West Berlin and refugees from East Germany and Eastern Europe , who were still able to freely enter

26649-653: The ninth century, chief among them being the Muspilli , Merseburg charms , and Hildebrandslied , and other religious texts (the Georgslied , Ludwigslied , Evangelienbuch , and translated hymns and prayers). The Muspilli is a Christian poem written in a Bavarian dialect offering an account of the soul after the Last Judgment , and the Merseburg charms are transcriptions of spells and charms from

26838-517: The northerly forecourt of the new terminal close to the film shelter. On 8 May 1945, Western Allied and German signatories of the German Surrender in Berlin and their entourage landed at Tempelhof airport. At the beginning of May, Weser Flugzeugbau opened a workshop in hangar 7 to repair streetcars . In the following weeks, Berliners raided all unguarded parts of the opened buildings searching for food or anything else useful in bartering in

27027-446: The nose door and raised cockpit concepts over to the design of the 747. The 747 was conceived while air travel was increasing in the 1960s. The era of commercial jet transportation, led by the enormous popularity of the Boeing 707 and Douglas DC-8 , had revolutionized long-distance travel. In this growing jet age, Juan Trippe , president of Pan American Airways (Pan Am), one of Boeing's most important airline customers, asked for

27216-477: The old and the new terminal searching for treasures, hidden places and documents, opening all rooms. During their search, they blew up the fortified entrance to a three-level bomb shelter for celluloid films of the Hansa Luftbild GmbH, a Luft Hansa subsidiary specialising in aerial photography. The explosion immediately ignited the celluloid, turning the film shelter under the northern office wing of

27405-529: The operation and maintenance of associated passenger, cargo and mail handling facilities. These changes gave a major boost to West Berlin's fledgeling post-war scheduled air services. On 8 July 1951, BEA transferred its operations from Gatow to Tempelhof, thus concentrating all West Berlin air services at Berlin's iconic city centre airport. BEA's move to Tempelhof resulted in a significant increase in passenger numbers, as well as an increase in its Berlin-based fleet to six Douglas DC-3s. From then on, several of

27594-446: The original -100, the -100B was offered with Pratt & Whitney JT9D-7A, CF6-50, or Rolls-Royce RB211-524 engines. However, only RB211-524 (Saudia) and JT9D-7A (Iran Air) engines were ordered. The last 747-100B, EP-IAM was retired by Iran Air in 2014, the last commercial operator of the 747-100 and -100B. The development of the 747SP stemmed from a joint request between Pan American World Airways and Iran Air , who were looking for

27783-725: The original repairs in the new terminal. After the Allied Control Council had agreed upon West Berlin Air Corridors under control of the Berlin Air Safety Center , these opened in February 1946, enabling civil aviation at Tempelhof to restart. On 20 June 1948, Soviet authorities, claiming technical difficulties, halted all traffic by land and by water into or out of the western-controlled sectors of Berlin. The only remaining access routes into

27972-433: The original variants. With a ten-abreast economy seating, it typically accommodates 366 passengers in three travel classes . It has a pronounced 37.5° wing sweep , allowing a Mach 0.85 (490 kn; 900 km/h) cruise speed , and its heavy weight is supported by four main landing gear legs, each with a four-wheel bogie . The partial double-deck aircraft was designed with a raised cockpit so it could be converted to

28161-554: The past received long-haul, wide-bodied airliners , such as the Boeing 747 , the Lockheed L-1011 Tristar and the Lockheed C-5A Galaxy . The first of these three first appeared at Tempelhof on 18 September 1976, when Pan American World Airways (Pan Am) flew in Boeing 747SP Clipper Great Republic to participate in the static exhibition of contemporary military, non-combat and civil aircraft at

28350-554: The potential termination of 747 production due to insufficient demand and market for the aircraft. With a firm order backlog of 21 aircraft and a production rate of six per year, program accounting had been reduced to 1,555 aircraft. In October 2016, UPS Airlines ordered 14 -8Fs to add capacity, along with 14 options, which it took in February 2018 to increase the total to 28 -8Fs on order. The backlog then stood at 25 aircraft, though several of these were orders from airlines that no longer intended to take delivery. On July 2, 2020, it

28539-401: The presence of Pan Am chairman Najeeb Halaby . Instead of champagne, red, white, and blue water was sprayed on the aircraft. The 747 entered service on January 22, 1970, on Pan Am's New York–London route; the flight had been planned for the evening of January 21, but engine overheating made the original aircraft (Clipper Young America, registration N735PA) unusable. Finding a substitute delayed

28728-426: The production line on December 6, 2022, and was delivered on January 31, 2023. Boeing hosted an event at the Everett factory for thousands of workers as well as industry executives to commemorate the delivery. The Boeing 747 is a large, wide-body (two-aisle) airliner with four wing-mounted engines. Its wings have a high sweep angle of 37.5° for a fast, efficient cruise speed of Mach 0.84 to 0.88, depending on

28917-496: The project. Had this been refused, Boeing's survival would have been threatened. The firm's debt exceeded $ 2 billion, with the $ 1.2 billion owed to the banks setting a record for all companies. Allen later said, "It was really too large a project for us." Ultimately, the gamble succeeded, and Boeing held a monopoly in very large passenger aircraft production for many years. On January 15, 1970, First Lady Pat Nixon christened Pan Am's first 747 at Dulles International Airport in

29106-462: The pronunciation of the ending -ig as [ɪk] instead of [ɪç]. In Northern Germany, High German was a foreign language to most inhabitants, whose native dialects were subsets of Low German. It was usually encountered only in writing or formal speech; in fact, most of High German was a written language, not identical to any spoken dialect, throughout the German-speaking area until well into the 19th century. However, wider standardization of pronunciation

29295-551: The separate US and British airlift efforts, the Allies created a unified command – the Combined Airlift Task Force under Maj. Gen. William H. Tunner , USAF – at Tempelhof. To facilitate the command and control, as well as the unloading of aircraft, the USAF 53d Troop Carrier Squadron was temporarily assigned to Tempelhof. The grass runways usual in Germany until then could not cope with the great demand, and

29484-493: The site was used as a parade field by the Prussian army from 1720 to the start of World War I . In 1909, French aviator Armand Zipfel made the first flight demonstration in Tempelhof, followed by Orville Wright later that same year. Tempelhof was first officially designated as an airport on 8 October 1923. Deutsche Luft Hansa was founded in Tempelhof on 6 January 1926. The old terminal, originally constructed in 1927, became

29673-430: The standard 747. The initial 747SR model, the -100SR, had a strengthened body structure and landing gear to accommodate the added stress accumulated from a greater number of takeoffs and landings. Extra structural support was built into the wings, fuselage, and the landing gear along with a 20% reduction in fuel capacity. The initial order for the -100SR – four aircraft for Japan Air Lines (JAL, later Japan Airlines ) –

29862-546: The states of North Dakota and South Dakota , German is the most common language spoken at home after English. As a legacy of significant German immigration to the country , German geographical names can be found throughout the Midwest region , such as New Ulm and Bismarck (North Dakota's state capital), plus many other regions. A number of German varieties have developed in the country and are still spoken today, such as Pennsylvania Dutch and Texas German . In Brazil,

30051-402: The still unfurnished main hall and hangars 3 to 7 of the new terminal, which were supplied by a railway and trucks via a connecting tunnel. Hangars 1 and 2 were not used to assemble aircraft as these were already used by Luft Hansa for its own planes. Aircraft parts were brought in from all over the city while complete aircraft engines were trucked to Tempelhof. Once the airframes were complete and

30240-528: The subsidised rate under this system, the passenger was required to purchase a round-trip ticket for a scheduled internal German flight from/to West Berlin in Germany. Once he/she had checked-in at the airport, the airline collected a coupon attached to his/her ticket, which was subsequently handed in to the relevant German authorities for reimbursement.) By the early 1960s, a number of UK independents and US supplementals began operating regular charter flights from Tempelhof. These carried both inbound tourists from

30429-456: The terminal building, built between 1936 and 1941, forms a 1.2-kilometre-long (0.75 mi) quadrant . Arriving passengers walked through customs controls to the reception hall. Tempelhof was served by the U6 U-Bahn line along Mehringdamm and up Friedrichstraße ( Platz der Luftbrücke station ). Zentralflughafen Tempelhof-Berlin had the advantage of a central location just minutes from

30618-500: The third most commonly learned second language in the United States in K-12 education. The language has been influential in the fields of philosophy, theology, science, and technology. It is the second most commonly used language in science and the third most widely used language on websites . The German-speaking countries are ranked fifth in terms of annual publication of new books, with one-tenth of all books (including e-books) in

30807-519: The third-busiest airport in Europe. From 6 June of that year, Pan Am. began re-equipping its Tempelhof-based fleet with larger, pressurised Douglas DC-6B propliners . Compared with the DC-4, the new type had 16 additional seats. In 1958, BEA began replacing its piston airliners with Vickers Viscount 701 turboprop aircraft, in a high-density 63-seat single class seating arrangement. Up to ten new, state-of-the-art Vickers Viscount 802s , which featured

30996-496: The time due to the large number of war-surplus C-54 Skymasters. 1950 was also the year Air France joined Pan Am at Tempelhof. Air France resumed operations to Tempelhof following their cessation during the war years. This was furthermore the time Allied restrictions on the carriage of local civilians on commercial airline services from/to West Berlin were lifted. It entailed transferring responsibility for processing all commercial flights to West Berlin's city government, including

31185-474: The time the overseas division of American Airlines , inaugurated the first commercial air link serving Tempelhof after the war with a flight from New York via Shannon , Amsterdam and Frankfurt on 18 May 1946. This was followed by AOA's inauguration of West Berlin's first dedicated domestic air link between Tempelhof and Frankfurt's Rhein-Main Airport on 1 March 1948. AOA was the only commercial operator at Tempelhof to maintain its full flying programme for

31374-434: The turbine casings after a short period of service. The problems delayed 747 deliveries for several months; up to 20 aircraft at the Everett plant were stranded while awaiting engine installation. The program was further delayed when one of the five test aircraft suffered serious damage during a landing attempt at Renton Municipal Airport , the site of Boeing's Renton factory . The incident happened on December 13, 1969, when

31563-422: The variant. The sweep also reduces the wingspan, allowing the 747 to use existing hangars . Its seating capacity is over 366 with a 3–4–3 seat arrangement (a cross section of three seats, an aisle, four seats, another aisle, and three seats) in economy class and a 2–3–2 layout in first class on the main deck. The upper deck has a 3–3 seat arrangement in economy class and a 2–2 layout in first class. Raised above

31752-555: The world being published in German. German is most closely related to other West Germanic languages, namely Afrikaans , Dutch , English , the Frisian languages , and Scots . It also contains close similarities in vocabulary to some languages in the North Germanic group , such as Danish , Norwegian , and Swedish . Modern German gradually developed from Old High German , which in turn developed from Proto-Germanic during

31941-463: The world's largest building by volume . The 747's first flight took place on February 9, 1969, and the 747 was certified in December of that year. It entered service with Pan Am on January 22, 1970. The 747 was the first airplane called a " Jumbo Jet " as the first wide-body airliner. The 747 is a four-engined jet aircraft , initially powered by Pratt & Whitney JT9D turbofan engines, then General Electric CF6 and Rolls-Royce RB211 engines for

32130-518: The world's first with an underground railway . The station has since been renamed Paradestraße , because the rebuilding of the airport in the 1930s required the airport access to be moved to a major intersection with a station now called Platz der Luftbrücke after the Berlin Airlift . As part of Albert Speer 's plan for the reconstruction of Berlin during the Nazi era, Prof. Ernst Sagebiel

32319-476: The world, both to Irish flag carrier Aer Lingus . No 747s were sold to any American carrier for almost three years. When economic problems in the US and other countries after the 1973 oil crisis led to reduced passenger traffic, several airlines found they did not have enough passengers to fly the 747 economically, and they replaced them with the smaller and recently introduced McDonnell Douglas DC-10 and Lockheed L-1011 TriStar trijet wide bodies (and later

32508-600: The written form of German. One of the central events in the development of ENHG was the publication of Luther's translation of the Bible into High German (the New Testament was published in 1522; the Old Testament was published in parts and completed in 1534). Luther based his translation primarily on the Meißner Deutsch of Saxony , spending much time among the population of Saxony researching

32697-540: Was US$ 24M (174.8M today). Responding to requests from Japanese airlines for a high-capacity aircraft to serve domestic routes between major cities, Boeing developed the 747SR as a short-range version of the 747-100 with lower fuel capacity and greater payload capability. With increased economy class seating, up to 498 passengers could be carried in early versions and up to 550 in later models. The 747SR had an economic design life objective of 52,000 flights during 20 years of operation, compared to 24,600 flights in 20 years for

32886-429: Was a "neutral" language as there were virtually no English native speakers in Namibia at that time. German, Afrikaans, and several indigenous languages thus became "national languages" by law, identifying them as elements of the cultural heritage of the nation and ensuring that the state acknowledged and supported their presence in the country. Today, Namibia is considered to be the only German-speaking country outside of

33075-569: Was also the year Pan Am withdrew its last DC-4 from Tempelhof. As a result, all of the airline's Berlin routes were exclusively served with DC-6Bs as of 27 June of that year. Although the DC-6B was a less advanced aircraft than either the Viscount or the Caravelle , it was more economical. By the early 1960s, Pan Am had a fleet of 15 DC-6Bs stationed at its Tempelhof base, which were configured in

33264-405: Was also the year US supplemental Saturn Airways began operating a comprehensive inclusive tour (IT) charter flight programme from Tempelhof under contract to local package holiday consolidator Flug-Union Berlin, using Douglas DC-6A/Cs and DC-7Cs . On 2 December of that year, a Boeing 727-100 became the first jet aircraft to land at Tempelhof. Boeing had leased the aircraft to Pan Am for

33453-547: Was an artificial standard that did not correspond to any traditional spoken dialect. Rather, it was based on the pronunciation of German in Northern Germany, although it was subsequently regarded often as a general prescriptive norm, despite differing pronunciation traditions especially in the Upper-German-speaking regions that still characterise the dialect of the area today – especially

33642-407: Was announced on October 30, 1972; rollout occurred on August 3, 1973, and the first flight took place on August 31, 1973. The type was certified by the FAA on September 26, 1973, with the first delivery on the same day. The -100SR entered service with JAL, the type's sole customer, on October 7, 1973, and typically operated flights within Japan. Seven -100SRs were built between 1973 and 1975, each with

33831-446: Was designated as an airport by the Reich Ministry of Transport on 8 October 1923. The old terminal was originally constructed in 1927. In anticipation of increasing air traffic, the Nazi government began an enormous reconstruction in the mid-1930s. While it was occasionally cited as the world's oldest operating commercial airport, the title was disputed by several other airports , and is no longer an issue since its closure. Tempelhof

34020-427: Was established on the basis of public speaking in theatres and the media during the 20th century and documented in pronouncing dictionaries. Official revisions of some of the rules from 1901 were not issued until the controversial German orthography reform of 1996 was made the official standard by governments of all German-speaking countries. Media and written works are now almost all produced in Standard German which

34209-510: Was first delivered in October 2011. The 747 is the basis for several government and military variants, such as the VC-25 ( Air Force One ), E-4 Emergency Airborne Command Post, Shuttle Carrier Aircraft , and some experimental test aircraft such as the YAL-1 and SOFIA airborne observatory. Initial competition came from the smaller trijet widebodies: the Lockheed L-1011 (introduced in 1972), McDonnell Douglas DC-10 (1971) and later MD-11 (1990). Airbus competed with later variants with

34398-403: Was one of Europe's three iconic pre- World War II airports, the others being London 's now defunct Croydon Airport and the old Paris–Le Bourget Airport . It acquired a further iconic status as the centre of the Berlin Airlift of 1948–49. One of the airport's most distinctive features is its huge, canopy -style roof extending over the apron, able to accommodate most contemporary airliners in

34587-419: Was ordered to replace the old terminal with a new terminal building in 1934. The airport halls and the adjoining buildings, intended to become the gateway to Europe and a symbol of Hitler's "world capital" Germania , are still known as one of the largest built entities worldwide, and have been described by British architect Sir Norman Foster as "the mother of all airports". With its façades of shell limestone ,

34776-440: Was reported that Boeing planned to end 747 production in 2022 upon delivery of the remaining jets on order to UPS and the Volga-Dnepr Group due to low demand. On July 29, 2020, Boeing confirmed that the final 747 would be delivered in 2022 as a result of "current market dynamics and outlook" stemming from the COVID-19 pandemic , according to CEO David Calhoun. The last aircraft, a 747-8F for Atlas Air registered N863GT, rolled off

34965-470: Was shortened for the longer-range 747SP in 1976, and the 747-300 followed in 1983 with a stretched upper deck for up to 400 seats in three classes. The heavier 747-400 with improved RB211 and CF6 engines or the new PW4000 engine (the JT9D successor), and a two-crew glass cockpit , was introduced in 1989 and is the most common variant. After several studies, the stretched 747-8 was launched on November 14, 2005, with new General Electric GEnx engines, and

35154-409: Was so short that the 747's full-scale mock-up was built before the factory roof above it was finished. The plant is the largest building by volume ever built, and has been substantially expanded several times to permit construction of other models of Boeing wide-body commercial jets. Before the first 747 was fully assembled, testing began on many components and systems. One important test involved

35343-614: Was soon replaced by Bell OH-13 Sioux . Further helicopters stationed over the years where Sikorsky H-19 Chikasaw (1958–1964), Sikorsky H-34 Choctaw (1962–1964), Bell UH-1B (1964–1971)and finally Bell UH-1H (May 1971– August 1994). Fixed wing aircraft stationed at Tempelhof were Cessna O-1 Bird Dog (1965–1975), De Havilland Canada U-6 Beaver (1968 – January 1980), Cessna O-2A (1975–1979), Pilatus UV-20A Chiricahua (1979–1991), Beechcraft U-8D Seminole (1960s), Beechcraft U-21 (1970s–1986 and 1991–1994), as well as Beechcraft C-12C (1986–1991). American Overseas Airlines (AOA), at

35532-606: Was two-thirds of the normal time. The schedule was so fast-paced that the people who worked on it were given the nickname "The Incredibles". Developing the aircraft was such a technical and financial challenge that management was said to have "bet the company" when it started the project. Due to its massive size, Boeing subcontracted the assembly of subcomponents to other manufacturers, most notably Northrop and Grumman (later merged into Northrop Grumman in 1994) for fuselage parts and trailing edge flaps respectively, Fairchild for tailplane ailerons, and Ling-Temco-Vought (LTV) for

35721-531: Was unable to attract enough interest to enter production. A year later, Boeing switched from the 747X studies to pursue the Sonic Cruiser , and after the Sonic Cruiser program was put on hold, the 787 Dreamliner . Some of the ideas developed for the 747X were used on the 747-400ER , a longer range variant of the 747-400. After several variants were proposed but later abandoned, some industry observers became skeptical of new aircraft proposals from Boeing. However, in early 2004, Boeing announced tentative plans for
