185-622: Situated adjacent to the Mexico–United States border , Tijuana Airport is a geographically binational airport, having direct access to its terminal from Mexico, and from its Cross Border Xpress (CBX) terminal in the United States. This rare feature allows passengers with a boarding pass to walk across a bridge crossing the border. The CBX terminal handled 4,288,000 passengers in 2023, constituting approximately one-third of all passenger movements at Tijuana Airport. The airport ranks as

370-541: A Boeing 777-200 , but in September 2014, these flights were relocated to Monterrey. Additionally, Aeroméxico provided services to Shanghai from 2006 to 2009 and then again from 2010 to 2019. In 2012, regional airline Calafia Airlines initiated bi-weekly flights to Tijuana, following the route Tijuana- Loreto -La Paz. Viva Aerobus temporarily suspended its operations in Tijuana in 2014. Interjet started operations on

555-470: A layover mostly to refuel. Since the flight currently only flies to the airport as a layover, passengers inside the airplane are not allowed to exit the aircraft and must wait until landing at Shenzhen, their final and intended destination. Likewise, passengers at the terminal are not allowed to board the plane either. However, it is worth mentioning that China Southern Airlines is considering adding Tijuana to its route, allowing passengers to board and de-board

740-610: 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

925-459: 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

1110-590: 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

1295-548: 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

1480-429: 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 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

1665-736: A U.S.–Mexico border shutdown could be expected following the COVID-19 public health emergency. According to HRW, the new rule introduced by the CDC overlooks the fact that the U.S. is obligated to protect refugees from return to conditions threatening prosecution, as per treaties. President Joe Biden's border executive plan as the COVID-19 restrictions – known as Title 42 – expired in May 2023. Under Title 42, which had been in effect since March 2020, many border crossers have been quickly deported to Mexico without

1850-402: A calendar year. Tijuana Airport, inaugurated as the ' Aeropuerto Federal de Tijuana' on May 1, 1951, replaced the former airport located on today's Aguacaliente Boulevard . The initial passenger terminal was situated on the southwest side of the airport grounds, facing the present terminal. In 1954, Mexicana de Aviación began direct flights from Tijuana to Mexico City . In 1965, as part of

2035-471: A chance for asylum. 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 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

2220-494: A check for VEE. APHIS imposes similar testing and certification requirements on horses from other parts of the world but without the quarantine for VEE. These horses are held in quarantine—usually three days—or until tests are completed. Because the disease equine piroplasmosis (equine babesiosis ) is endemic in Mexico but not established in the U.S., transportation of horses from Mexico to the U.S. requires evaluation of horses for

2405-494: A consortium headquartered in Guadalajara . This consortium included Spanish investors Unión Fenosa , Dragados , and Aeropuertos Españoles y Navegación Aérea (AENA) , along with Mexican strategic investor Grupo Empresarial Ángeles , managing a total of 12 airports. Under the airport privatization concession in 2002, an expansion project was undertaken by the airport management. The extension of concourses A and B allowed for

2590-868: A crisis, declaring bankruptcy and undergoing restructuring, which impacted its services in Tijuana. In 1991, TAESA initiated flights to Mexico City with a stop in Los Mochis, employing Boeing 727 equipment. In 2006, Aeroméxico launched the Tijuana- Acapulco route, utilizing Boeing 737-700 aircraft. The same year, Líneas Aéreas Azteca initiated flights to Oakland . Viva Aerobus began operations in Tijuana from its Monterrey hub in 2006, operating Boeing 737-300 equipment. Interjet introduced flights to Mexico City in 2008. In 2009, Mexicana closed routes to Culiacán and Puebla , ultimately declaring bankruptcy in 2010. From 2006 until September 2014, Aeroméxico operated three weekly flights to Tokyo-Narita with

2775-592: A doubling of the terminal's capacity. Furthermore, several taxiways were expanded to accommodate larger aircraft, such as the Boeing 747 . Throughout its history, Tijuana Airport has served as a strategic hub for various airlines. In the 1990s, up until its discontinuation of services in 2006, Aero California utilized the airport as a hub , offering services to over 12 domestic cities. Other airlines such as TAESA , Aerolíneas Internacionales , Líneas Aéreas Azteca , and Avolar also established their hubs in Tijuana during

2960-472: A fleet of Douglas DC-6 aircraft . In 1971, Aeroméxico initiated flights to Mexico City with Douglas DC-8 equipment, and by 1976, it expanded its services with McDonnell Douglas DC-10 equipment to Guadalajara and Mexico City. Mexicana reinaugurated its Tijuana flights in 1978, operating a daily flight from Mexico City with a stop in La Paz, using Boeing 727 equipment. In 1983, Aero California launched

3145-452: 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

3330-428: 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,

3515-405: 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

3700-540: A high-tech control tower , one of the tallest in Mexico. On the opposite side of the Main Terminal building, there is another terminal, the Old Airport Terminal, and a former runway. The Old Airport Terminal houses military facilities, and south of the former runway, 4 remote positions are located, mostly used by cargo airliners. These are linked by a shorter taxiway to the main runway. The airport

3885-437: 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

4070-459: A locked and crowded detention center cell in northern Mexico, with motives ranging from pending deportation to overcrowding and lack of access to drinking water. The border separating Mexico and the U.S. is the most frequently crossed international boundary in the world, with approximately 350 million legal crossings taking place annually. Border crossings take place by roads, pedestrian walkways, railroads and ferries. From west to east, below

4255-403: 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

4440-410: 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

4625-508: 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 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

4810-457: A negative image. There are around 11.5 million undocumented workers in the U.S. today, and 87% of undocumented immigrants have been living in the U.S. for more than 7 years. Local economies that develop on the Mexican side capitalize not only on available skills but also on available, usually discarded, materials. Small businesses trade in clothes that are purchased by the pound and cardboard from

4995-426: A negative test for EIA. Horses from Mexico must have a health certificate; pass negative tests for EIA, dourine, glanders, and EP at a USDA import center; and undergo precautionary treatments for external parasites at the port of entry. Horses from other Western Hemisphere countries must have the same tests as those from Mexico and, except for horses from Argentina , must be held in quarantine for at least seven days as

5180-421: 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

5365-687: 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 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

5550-544: A point 32 km (20 mi) south of the Gila River confluence. The border then follows a series of lines and parallels totaling 859 km (534 mi). First, it follows a straight line from the Colorado River to the intersection of the 31° 20′ parallel north and the 111th meridian west . It then proceeds eastwards along the 31° 20′ parallel north up to a meridian 161 km (100 mi) west of

5735-459: A prohibition by Mexican law, public taxis from Mexican cities may drop passengers at the airport but cannot pick up passengers from the terminal. The airport, therefore, offers transportation for passengers from the terminal to any point in the city on SAAT Taxis Servicio Aeroportuario de Autotransporte Terrestre (Terrestrial Transport Airport Service), an airport government-leased taxi company. This and other authorized taxi carriers may be reached at

5920-462: 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

6105-503: A result, the effect funneled more immigrants to their death even with the assistance of coyotes (smugglers). Not only has this approach caused fatalities throughout the U.S.–Mexico border, but it has even stirred up a nuisance for documented immigrants and American citizens. There has been general concern about the Border Patrol and other agencies abusing their authority by racial profiling and conducting unwarranted searches outside

6290-447: 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

6475-507: A single 3,000 metres (9,800 ft) long 09/27 runway, a parallel taxiway , and an apron with 23 parking positions, mostly arranged for narrow-body commercial aircraft surrounding the two terminal pier buildings . There are 12 positions with direct access to the terminal and 11 remote positions. Adjacent to this area, there is a general aviation apron offering stands for fixed-wing aircraft and heliports for private aviation, as well as hangars and maintenance facilities. The airport features

6660-496: 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

6845-465: A snack bar. The concept of a cross-border terminal was initially proposed in the 1960s as part of a broader plan to modernize Mexico's airports. Despite multiple developments and setbacks, construction commenced in 2013. With an initial estimated cost of US$ 78 million and a final completion cost of US$ 120 million, it officially opened on December 9, 2015. Building E, which hosts the parking facilities at Tijuana's Terminal underwent restructuring to support

7030-463: A stopover in Mexico City–AIFA. The airport may be reached from Downtown Tijuana or Zona Rio by local bus. It costs $ 11.00 MXN (US$ 0.60). Volaris provides a shuttle service from San Diego, California , to Tijuana Airport, allowing San Diego residents to make connections within Mexico. Passengers cannot board this shuttle at San Diego International Airport but instead take a local bus from

7215-492: A surface area of 420 square metres (4,500 sq ft), housing government offices, administrative offices, a pilots lounge, and a passenger lounge. Two aviation schools are based at this terminal, along with one cargo airline operating there. Brown Field Municipal Airport ( SDM ) in San Diego, California lies just over 1,900 metres (6,200 ft) north of the airport, with a similar runway length and orientation. SDM

7400-495: A terminal capable of accommodating larger aircraft were constructed north of the existing runway. The new runway direction impacted Tijuana's approach, particularly over Cerro San Isidro , a 792 metres (2,598 ft) high land obstacle, causing an increase in the east approach glide slope beyond 3 degrees and hindering a full Instrument Landing System (ILS) approach on runway 27, necessary during adverse weather conditions. The original terminal then transitioned into an air base for

7585-405: 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

7770-474: A valid Merchant Mariner Document when traveling in conjunction with official maritime business; or a valid U.S. military identification card when traveling on official orders. In August 2015, Mexico began enforcing a rule that all foreign citizens that plan to stay in the country for more than seven days or are travelling on business will have to pay a 330 pesos ($ 21) fee and show their passport. When animals are imported from one country to another, there

7955-622: A variety of terrains, ranging from urban areas to deserts. It is the most frequently crossed border in the world with approximately 350 million documented crossings annually. Illegal crossing of the border to enter the United States has caused the Mexico–United States border crisis . It is one of two international borders that the United States has, the other being the northern Canada–United States border ; Mexico has two other borders: with Belize and with Guatemala . Four American states border Mexico: California , Arizona , New Mexico and Texas . One definition of Northern Mexico includes only

8140-448: 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

8325-576: Is a general aviation field not set up for scheduled passenger service. Both SDM and TIJ are designated as ports of entry for their respective countries. Air Force Base Nr. 12 ( Spanish : Base Aérea Militar N.º 12, Tijuana, Baja California ) (B.A.M. No. 12) is a facility of the Mexican Air Force located on the airport grounds. Currently, it does not have an assigned air squadron. It has an aviation platform of 14,400 square metres (155,000 sq ft), one hangar, and other facilities for

8510-462: Is a list of the border city "twinnings"; cross-border municipalities connected by one or more legal border crossings. The total population of the borderlands—defined as those counties and municipios lining the border on either side—stands at some 12 million people. The San Ysidro Port of Entry is located between San Ysidro, California and Tijuana, Baja California . Approximately 50,000 vehicles and 25,000 pedestrians use this entry daily. In

8695-567: Is also used to a lesser extent for general aviation, housed at the General Aviation Building (GAB). Runway 09/27 runs east–west approximately 300 metres (980 ft) south of the U.S.-Mexico border. The approach to the runway is either from the east (normally) or from the west (when Santa Ana wind conditions exist). Due to prevailing winds, the 27 runway is Tijuana's main approach pattern. The airport can handle up to 10 million passengers per year and 360 flights per day. It

8880-469: Is by the means of "prevention through deterrence". Its primary goal is to completely prevent undocumented immigrants from entering the U.S. from Mexico rather than apprehending the unauthorized who are already in the country. As assertive as it was, "prevention through deterrence" was arguably unsuccessful, with a doubling in size of undocumented immigrants population during the two decades leading up to 2014. In order to effectively enforce border protection,

9065-572: Is capable of handling widebody aircraft such as the Boeing 787 and 747. The passenger terminal accommodates both arrival and departure services for domestic and international flights within a multi-story building, including two pier concourses with 20 gates. The ground floor of the main building includes check-in areas and an arrivals section featuring a baggage claim area and an arrivals hall. Here, passengers can access car rental services, taxi stands, snack bars, and souvenir shops. The first floor houses

9250-480: Is currently the airport’s second direct connection to the United States and its third international destination overall. Volaris remains as the largest operator in the airport, offering flights to more than 35 domestic destinations. Additionally, along with Viva Aerobus, it serves the longest domestic non-stop route in Mexico, from Tijuana to Cancún , with a flight time of over 4 hours. The airport features

9435-484: Is paralleled by U.S. Border Patrol interior checkpoints on major roads generally between 40 and 121 km (25 and 75 mi) from the U.S. side of the border, and garitas generally within 50 km (31 mi) of the border on the Mexican side. There are an estimated half a million illegal entries into the U.S. each year. Border Patrol activity is concentrated around border cities such as San Diego and El Paso which have extensive border fencing. This means that

Such animals include those from the U.S. that cross to Mexico and return, and animals from other countries that travel overland through Mexico or the U.S. before crossing the border. APHIS imposes precautions to keep out several equine diseases, including glanders , dourine , equine infectious anemia , equine piroplasmosis , Venezuelan equine encephalitis , and contagious equine metritis . APHIS also checks horses to prevent

9805-513: 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

The Border Patrol

11100-574: The Government Accountability Office released a report stating that the U.S. Border Patrol intercepted 61% of individuals illegally crossing the border in 2011, which translates to 208,813 individuals not apprehended. 85,827 of the 208,813 would go on to illegally enter the U.S., while the rest returned to Mexico and other Central American countries. The report also shows that the number of illegal border crossings has dropped. The apprehensions per (fiscal) year are shown in

The year 1969 marked the introduction of Operation Intercept , aimed at curbing narcotics flow between the U.S. and Mexico. Rising political pressure to reduce incursions into U.S. airspace resulted in the requirement to reorient the runway from 10/28 to 09/27. In 1970, a new 2,500 metres (8,200 ft) long runway (09/27) and

12025-506: 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

12210-499: 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 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

12395-399: The 1990s and early 2000s, operating extensive domestic networks. Notably, Avolar had its maintenance base at a large hangar facility in Tijuana, later acquired by Volaris. Volaris initiated operations in Tijuana in 2006, gradually expanding its services and transforming Tijuana into a hub with connections to more than 35 destinations. As the airport grew in significance, emerging as one of

12580-487: 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

12765-519: 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

12950-549: 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

13135-468: 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

13320-472: 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

13505-472: 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

13690-505: 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

13875-517: 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 , 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

14060-818: The Acapulco-Tijuana-Acapulco route in 2015, utilizing the Sukhoi Superjet 100 . On March 4, 2015, Volaris resumed the Tijuana-Oakland route, offering 2 flights per week. Initially launched in August 2009 and operating daily, the route was canceled due to poor results. On October 1, 2015, Aeroméxico Connect resumed flights from Tijuana to Monterrey, operated by the Embraer 170 . Viva Aerobus also resumed its flights in Tijuana on November 19, 2015, with Mexico City as its first route, marking

14245-459: 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

14430-717: The Cross Border Xpress (CBX) was officially opened, establishing a physical connection between the passenger terminal in Tijuana and a new terminal in San Diego . This innovative project facilitates seamless passenger crossings between the two countries, effectively transforming Tijuana Airport into a geographically binational airport with direct access from both Mexico and the United States. The realization of this project follows decades of planning and negotiations, addressing aspects such as border control , management, funding, and construction. Notably, on December 19, 2015,

14615-625: The El Paso-Juarez area, in effect transferring the land to the U.S.. By a treaty negotiated in 1963, Mexico regained most of this land in what became known as the Chamizal dispute and transferred 1.07 km (260 acres) in return to the U.S. Border treaties are jointly administered by the International Boundary and Water Commission (IBWC), which was established in 1889 to maintain the border, allocate river waters between

14800-761: The Line in El Paso ; Operation Rio Grande in McAllen ; Operation Safeguard in Tucson ; and the Arizona Border Control Initiative along the Arizona border. According to Vulliamy, one in five Mexican nationals will visit or work in the U.S. at one point in their lifetime. As of 2010, the border is guarded by more than 20,000 Border Patrol agents, more than at any time in its history. The border

14985-497: The Mexican Air Force, now known as the ' Aeropuerto Viejo' or old airport. During the 1970s, Tijuana experienced rapid growth, leading to expansions in both terminal and parking areas to meet escalating airport demand. In the 1980s, both terminal space and passenger parking at Tijuana Airport became insufficient to meet demand. In 1990, Mexico initiated its first two 10-year joint ventures with private investors. One of

15170-531: The Mexican border, serving approximately one-third of Tijuana Airport's passengers. It uniquely positions Tijuana Airport as a geographically binational airport. The CBX comprises a terminal building physically located on U.S. soil, adjacent to the border, and a 120 metres (390 ft) bridge across the border connecting to the Mexican immigration and customs facilities at Tijuana Airport. It facilitates direct access for U.S. passengers to Tijuana Airport and provides Mexican and international carriers with direct entry to

15355-405: The Mexican economy overall, 25% of it in the border regions. The U.S. Immigration Act of 1891 authorized the implementation of inspection stations at ports of entry along the Mexican and Canadian borders. The U.S. Immigration Act of 1917 required the passing of a literacy test and a head tax by Mexicans wanting to enter the U.S. legally; however, during World War I , when labor shortages grew,

15540-576: The National Plan of Airports introduced during President Diaz Ordaz's administration, the airport became part of the Government-owned corporation Aeropuertos y Servicios Auxiliares (ASA) . The growing population in Tijuana during the 1960s led to an increased demand for flights. The airport's 2,000 metres (6,600 ft) long runway , with an orientation of 10/28, had its northern end located less than 100 metres (330 ft) south of

15725-459: The Rio Grande under the 1905 convention, which occurred on 37 different dates from 1910 to 1976, the transferred land was small (ranging from one to 646 acres) and uninhabited. The Rio Grande Rectification Treaty of 1933 straightened and stabilized the river boundary through the highly developed El Paso-Juárez valley. Numerous parcels of land were transferred between the two countries during

15910-597: The Tijuana- Los Mochis -Guadalajara route with McDonnell Douglas DC-9 jets. Mexicana inaugurated the Guadalajara route in 1985, operating various aircraft, including Boeing 727, Boeing 757 , Airbus A318 , Airbus A319 , and Airbus A320 , over a span of 25 years. In the summer of 1987, Aeroméxico introduced flights to Bogotá , Colombia, utilizing Douglas DC-8-62 equipment on Mondays, Tuesdays, Wednesdays, and Saturdays. However, in 1988, Aeroméxico faced

16095-423: The U.S. Federal Bureau of Investigation to monitor suspicious activities and potential violence at the border. Within 10 years, frequent provocations caused border towns to transform into battlefields, which intensified transborder restrictions, brought federal soldiers to patrol the border, and caused the construction of fences and barriers between border towns. When the battles concluded, restrictions for crossing

16280-466: The U.S. Some items, like the used tires found everywhere along the border, are made into certain items that support local economies and define a border. The Secure Fence Act of 2006 was passed providing for the construction of 1,127 km (700 mi) of high-security fencing. Attempts to complete the construction of the Mexico–United States barrier have been challenged by the Mexican government and various U.S.–based organizations. In January 2013,

16465-413: The U.S. and the Mexican government's support for financial investments from the U.S. Railroads were built that connected the northern Mexican states more to the U.S. than to Mexico, and the population grew tremendously. The mining industry also developed, as did the U.S.'s control of it. By the early 20th century companies from the U.S. controlled 81% of the mining industry and had invested US$ 500 million in

16650-568: The U.S. by air: a valid passport ; a passport card ; a state enhanced driver's license or state enhanced non-driver ID card (available in Michigan , New York , Vermont , and Washington ) approved by the Secretary of Homeland Security; a trusted traveler program card ( Global Entry , NEXUS , FAST , or SENTRI ); an enhanced tribal identification card; a Native American Tribal Photo Identification Card; Form I-872 – American Indian Card;

16835-404: The U.S. ceded 6 islands in the Rio Grande to Mexico. At the same time, Mexico ceded 3 islands and 2 bancos to the U.S. This transfer, which had been pending for 20 years, was the first application of Article III of the 1970 Boundary Treaty. On March 27, 2023, at least 38 detained migrants (mostly from Central America) were killed—and dozens more injured—in a fire started in protest inside

17020-408: The U.S. market. The building serves departure and arrival facilities. Departing passengers can enter the building on the U.S. side before crossing the pedestrian bridge over the border, clearing immigration and customs, and boarding flights in the departure concourses in Tijuana. Arrival passengers in Tijuana can access the bridge from the baggage claim area at the terminal in Tijuana and walk across

17205-401: The U.S. settled all outstanding boundary disputes and uncertainties related to the Rio Grande border. The U.S. states along the border, from west to east, are California , Arizona , New Mexico , and Texas . The Mexican states along the border are Baja California , Sonora , Chihuahua , Coahuila , Nuevo León , and Tamaulipas . Among the U.S. states, Texas has the longest stretch of

17390-488: The U.S. was between 1909 and 1911 in California, the first barrier built by Mexico was likely in 1918; barriers were extended in the 1920s and 1940s. The Banco Convention of 1905 between the U.S. and Mexico allowed, in the event of sudden changes in the course of the Rio Grande (as by flooding), for the border to be altered to follow the new course. The sudden changes often created bancos (land surrounded by bends in

17575-412: The U.S.' policies and regulations have looked to make border crossings more hazardous through the implementation of various operations, one of those being the "funnel effect". The tactic was meant to discourage migration from Mexico into the U.S. by forcing migrants to travel further around barriers where the terrain and weather are more risky, but the strategy was not as successful as initially planned. As

17760-440: The U.S., I-5 crosses directly to Tijuana, and the highway's southern terminus is this crossing. In 2005, more than 17 million vehicles and 50 million people entered the U.S. through San Ysidro . Among those who enter the U.S. through San Ysidro are transfronterizos , American citizens who live in Mexico and attend school in the U.S. It has influenced the every day lifestyle of people that live in these border towns . Along

17945-431: The U.S., 90% were from Mexico alone. In addition, there are more than 6 million undocumented Mexican nationals residing in the U.S. The border has a very high rate of documented and undocumented migrant crossings every year. With such a high rate of people crossing annually to the U.S., the country has invested in several distinct security measures. In 2010, President Barack Obama signed an appropriation bill which gave

18130-571: The United States and abroad typically choose to use San Diego International Airport , which is situated less than 30 kilometres (19 mi) northwest of Tijuana Airport. In 2022, an expansion of the passenger terminal was constructed. Named 'Nuevo Edificio Procesador' (New Processing Building), it features additional check-in counters, security lanes, boarding gates, and immigration facilities for both international flights and cross-border passengers entering from San Diego. The expansion aims to attract flight services to Asia and South America , with

18315-556: The accommodation of air force personnel. These facilities are located at The Old Airport Terminal. Notes: ^1 Viva flight to Hermosillo makes a stopover in San José del Cabo but it will be non-stop from May 2025. ^2 Viva flight to Mérida makes a stopover in Monterrey. ^3 Viva flight to Querétaro makes a stopover in San José del Cabo but it will be non-stop from May 2025. ^4 Viva flight to Tulum makes

18500-408: 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,

18685-462: 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

18870-472: The airport experienced its busiest day, recording a total of 164 flights between departures and arrivals. The airport's proximity to the U.S. border makes it an appealing option for cross-border travelers heading to Mexican cities. However, due to its close proximity to San Diego Airport and the high transportation taxes for international flights in Mexico, the airport has not been able to retain international destinations. Passengers traveling to destinations in

19055-480: The airport to the Amtrak Station at 1050 Kettner Blvd. on the corner of Broadway Ave, Downtown San Diego, CA 92101. There is no equivalent shuttle from Tijuana Airport back to downtown San Diego, as most people who connect between Tijuana Airport and San Diego pay to use the Cross Border Xpress and then take private vehicles or use Uber or taxi services since there is no public transportation from CBX. Due to

19240-422: The arrivals hall. This inflates taxi prices, forcing passengers to either pay them or walk outside the airport. Mexico%E2%80%93United States border The Mexico–United States border ( Spanish : frontera Estados Unidos–México ) is an international border separating Mexico and the United States , extending from the Pacific Ocean in the west to the Gulf of Mexico in the east. The border traverses

19425-666: The beginning of its current operating base and focus city service. From 2017 to 2018, Volaris Costa Rica initiated flights to San Salvador and Guatemala City . In 2018, the Chinese airline Hainan Airlines commenced three weekly flights from Beijing to Tijuana and Mexico City using Boeing 787-8 equipment. This service was put on hiatus in 2020 due to the COVID-19 pandemic . Interjet also ceased all operations in Tijuana that year after filing for bankruptcy and becoming defunct. On December 26th, 2023, newly incorporated state-owned airline Aerolínea del Estado Mexicano (operating under

19610-460: The border every day is causing air pollution in San Ysidro and Tijuana. The emission of carbon monoxide (CO) and other vehicle related air contaminants have been linked to health complications such as cardiovascular disease, lung cancer, birth outcomes, premature death, obesity, asthma and other respiratory diseases. The high levels of traffic collusion and the extended wait times has affected

19795-468: The border into U.S. customs and immigration facilities at the CBX terminal. The building's design is the work of the late Mexican architect Ricardo Legorreta . Its central articulator node, dividing flows and functions, is a purple open central courtyard with an ash tree and a reflecting pool , referencing vernacular Mexican architecture . The arrivals hall features car rental facilities, bus agencies, and

19980-572: The border regions reflected this. As the infrastructure of communities on the U.S. side continued to improve, the Mexican side began to fall behind in the construction and maintenance of important transportation networks and systems necessary to municipal development. Although the Mexican Revolution caused insecurity in Mexico, it also strained U.S.–Mexico relations. With the Mexican Revolution lasting for 10 years, ending in 1920, and World War I simultaneously occurring between 1914 and 1918,

20165-420: The border was reaffirmed in the 1828 Treaty of Limits . Mexico attempted to create a buffer zone at the border that would prevent possible invasion from the north. The Mexican government encouraged thousands of their own citizens to settle in the region that is now known as Texas and even offered inexpensive land to settlers from the U.S. in exchange for populating the area. The influx of people did not provide

20350-489: The border were relaxed and most soldiers were sent home; however, the fences remained as a physical reminder of the division between the two nations. As years passed, more fences and higher barriers were established as attentions focused on the boundary demarcation between the U.S. and Mexico. The first international bridge was the Brownsville & Matamoros International Bridge built in 1910. The first barrier built by

20535-467: The border with Mexico, while California has the shortest. Among the states in Mexico, Chihuahua has the longest border with the U.S., while Nuevo León has the shortest. Along the border are 23 U.S. counties and 39 Mexican municipalities . In the mid-16th century, after the discovery of silver, settlers from various countries and backgrounds began to arrive in the area. This period of sparse settlement included colonizers from different backgrounds. The area

20720-405: The border, according to Mexican political scientist Armand Peschard-Sverdrup . The economic development of the border region on the Mexican side of the border depended largely on its proximity to the U.S., because of its remoteness from commercial centers in Mexico. During the years of Mexican President Porfirio Díaz , between 1876 and 1910, the border communities boomed because of close ties to

20905-462: 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

21090-439: The coast of Baja California, there are neighborhoods of Americans living in Tijuana, Rosarito Beach , and Ensenada , whose residents commute to the U.S. daily to work. Additionally, many Mexicans also enter the U.S. to commute daily to work. In 1999, 7.6% of the labor force of Tijuana was employed in San Diego. The average wait time to cross into the U.S. is approximately an hour. The thousands of vehicles that transit through

21275-471: 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

21460-491: The construction period, 1935–1938. At the end, each nation had ceded an equal area of land to the other. The Boundary Treaty of 1970 transferred an area of Mexican territory to the U.S., near Presidio and Hidalgo, Texas , to build flood control channels. In exchange, the U.S. ceded other land to Mexico, including five parcels near Presidio, the Horcon Tract and Beaver Island near Roma, Texas . On November 24, 2009,

21645-458: The country's largest hubs, plans for a new terminal were contemplated, though no tangible progress has been made. Between 2011 and 2012, significant renovations occurred in the passenger terminal, particularly in Concourses A and B. These enhancements included the establishment of new customs and international arrivals facilities and the construction of a new bus terminal. On December 9, 2015,

21830-671: The defense that Mexico had hoped for and instead Texas declared its independence in 1836, which lasted until 1845 when the U.S. annexed it. The constant conflicts in the Texas region in the mid-19th century eventually led to the Mexican–American War , which began in 1846 and ended in 1848 with the Treaty of Guadalupe Hidalgo . In the terms of the peace treaty, Mexico lost more than 2,500,000 square kilometers (970,000 sq mi) of land, 55% of its territory, including all of what

22015-475: 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

22200-508: The division between the U.S. and Mexico began to polarize the two nations. Constant battles and raids along the border made both authorities nervous about borderland security. The Zimmerman Telegram , a diplomatic cable sent by Germany but intercepted and decrypted by British intelligence, was meant to bait Mexico into war with the U.S. in order to reconquer what was taken from them during the Mexican-American War. This inspired

22385-412: 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

22570-574: The east end of the terminal, where passengers board their aircraft directly from the apron. Concourse A serves domestic flights and features sitting areas with shops and food stands. It has nine gates: gates 1-5 are located on the top floor and are equipped with jet bridges , while gates 6-9 are located on the ground floor, where passengers board their aircraft directly from the apron. Airlines operating from this satellite include Aeromexico , Volaris , Magnicharters , and Calafia Airlines . Concourse B serves domestic and international flights. It features

22755-490: 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

22940-425: 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

23125-403: 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

23310-409: 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

23495-486: 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

23680-504: 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

23865-420: The exception of the 40 km (25 mi) border zone, but still within the 161 km (100 mi) border zone. In 2012, Border Patrol agents made over 364,000 arrests of people illegally entering the country. Considerable success has been achieved in restoring integrity and safety to the border, by putting in place a border-control strategy. These include Operation Gatekeeper in San Diego ; Operation Hold

24050-433: 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

24235-410: 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

24420-411: 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 ,

24605-431: 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

24790-541: 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

24975-472: The flow of illegal immigrants is diverted into rural mountainous and desert areas, leading to several hundred migrant deaths along the Mexico–U.S. border of those attempting to cross into the U.S. from Mexico illegally and vice versa. Undocumented labor contributes $ 395 billion to the economy every year. While the U.S. is in favor of immigration, the increase in undocumented immigration has given border-crossing

25160-442: The goal of turning Tijuana Airport into a convenient alternative to U.S. airports for connecting passengers traveling between the two continents. Future plans for the airport include the addition of a hotel and a new bus terminal. In 1954, Mexicana de Aviación introduced direct flights from Tijuana to Mexico City. During the '70s, the cargo airline AeroCarga offered flights from Tijuana to La Paz , Mexico City, and Mérida , utilizing

25345-429: The graph; they reached a maximum of over 1.643 million in the year 2000. Similar numbers had been reached in 1986 with over 1.615 million. The increase of border security throughout the years has progressively made crossings at the U.S.–Mexico border more dangerous, which has developed a human rights crisis at the border. The number of migrant deaths occurring along the U.S.–Mexico border has dramatically increased since

25530-576: The implementation of the funnel effect. Along the Arizona-Mexico border, only seven migrant deaths were recorded in 1996; however, the remains of over 2,000 migrants were discovered from 2001 to 2012. Since the majority of deaths occur in rural areas, where extreme temperatures are common, it is likely the number of recorded deaths are far below the total. Because of the harsh, inaccessible terrain, human remains may not be found for years or ever. The Human Rights Watch cited on April 22, 2020, that

25715-496: The initial projects involved expanding both the departure concourse and parking areas. The year 1995 marked a significant change with the publication of the 'Ley de Aeropuertos' (Airports Law) by the Department of Communications and Transportation (Secretaría de Comunicaciones y Transporte) , marking the beginning of Mexico's airport privatization program. In 1999, Tijuana Airport joined Grupo Aeroportuario del Pacífico (GAP),

25900-489: The introduction of ticks and other parasites. In the Lower Rio Grande Valley, U.S. Department of Agriculture inspectors look for horses and livestock that stray across the border carrying ticks. These animals are often called wetstock, and the inspectors are referred to as tickriders. Per APHIS, horses originating from Canada can enter the U.S. with a Canadian government veterinary health certificate and

26085-466: 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

26270-442: The main hall, which features a security checkpoint and an airside corridor leading to Concourses A and B. This zone is equipped with food stands, duty-free shops, and a VIP lounge . The gates are located in two piers, designated A and B, which are connected to the main terminal. It is designed so that international flights can be handled at Concourse B and domestic flights at both concourses. Additionally, gates 19 and 20 are located at

26455-419: The mental health, stress levels, and aggressive behavior of the people who cross frequently. The San Ysidro border is heavily policed, separated by three walls, border patrol agents and the U.S. Immigration and Customs Enforcement . Tijuana is the next target for San Diegan developers because of its fast-growing economy, lower cost of living, cheap prices and proximity to San Diego. While this would benefit

26640-549: 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

26825-457: The name Mexicana de Aviación, in honor of the defunct airline) commenced daily flights to Tijuana using Boeing 737 equipment from the Mexican Air Force . The airline used to operate flights twice a day, however one of the two designated flights was abruptly terminated. The airline now operates daily flights once a day. From 2020 to 2023, the airport had no international service due to the pandemic imposing heavier restrictions on air travel. After

27010-614: 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 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

27195-466: The new bridge's structure. The project received accolades for its design and innovation and has undergone renovations and additions, including a new restroom facility and duty-free area completed in 2020. The General Aviation Building (GAB) is used for general/non-commercial aviation or private jets . The GAB is designed to receive up to 120 persons per hour and has all the services for the convenience of passengers during their private flights. It covers

27380-417: 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

27565-446: 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

27750-407: The once disputed lands, many of whom were Mexican nationals. Following the establishment of the current border, several towns sprang up along this boundary, and many of the Mexican citizens were given free land in the northern regions of Mexico in exchange for returning and repopulating the area. The Treaty of Guadalupe Hidalgo and another treaty in 1884 were the agreements originally responsible for

27935-446: 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

28120-599: The pandemic officially ended, restrictions were lifted and international service officially resumed on February 15, 2024, with American Eagle launching daily flights to Phoenix , Arizona using Embraer E175 equipment. This marks the first direct connection to the airport managed by American Eagle. On May 11th, 2024, China Southern Airlines launched the bi-weekly Shenzhen -Mexico City route, using Airbus A350 equipment. The flight departs from Shenzhen and flies directly to Mexico City’s busiest airport with no stops. When returning to Shenzhen, it stops at Tijuana’s airport as

28305-417: The plane at the airport. If this route is implemented, it would be the airport’s first direct connection managed by China Southern Airlines. It would also be the airport’s second direct connection to China and, consequently, Asia. On July 12th, 2024, after a four-year hiatus, Hainan Airlines resumed its Beijing-Tijuana-Mexico City / Mexico City-Tijuana-Beijing route, retaining the three weekly flights and using

28490-544: The point where the Rio Grande crosses the 31° 47′ parallel north, It then proceeds northwards along that meridian up to the 31° 47′ parallel north and then eastwards along that parallel until it meets the Rio Grande. According to the International Boundary and Water Commission , the continental border then follows the middle of the Rio Grande—according to the 1848 Treaty of Guadalupe Hidalgo between

28675-466: The poor run the risk of being impacted by the gentrification of Tijuana. In late 2006, the U.S. Department of Homeland Security (DHS) announced a rule regarding new identification requirements for U.S. citizens and international travelers entering the U.S. implemented on January 23, 2007. This final rule and first phase of the WHTI specifies nine forms of identification, one of which is required to enter

28860-610: 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

29045-401: 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

29230-548: The presence of this disease. A leading exception to this rule is the special waiver obtained by riders participating in the Cabalgata Binacional Villista (see cavalcade ). Import from the U.S. to Mexico requires evidence within the prior 45 days of freedom from EIA, among other requirements. Data from the U.S. Border Patrol Agency's 2010 annual report shows that among the total number of border crossings without documentation from various countries into

29415-426: 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

29600-496: 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

29785-418: The provisions were temporarily suspended. The U.S. Immigration Act of 1924 established the U.S. Border Patrol . The Mexican Revolution , caused at least partially by animosity toward foreign ownership of Mexican properties, began in 1910. The revolution increased the political instability in Mexico but did not significantly slow U.S. investment. It did reduce economic development within Mexico, however, and

29970-417: The river that became segregated from either country by a cutoff, often caused by rapid accretion or avulsion of the alluvial channel), especially in the lower Rio Grande Valley. When these bancos are created, the International Boundary and Water Commission investigates if land previously belonging to the U.S. or Mexico is to be considered on the other side of the border. In all cases of these adjustments along

30155-459: The same Boeing 787-8 equipment it used to operate before the COVID-19 pandemic . This meant the airport had now officially resumed direct passenger connections with Asia and it now had the only direct passenger connection to China in the San Diego–Tijuana metropolitan area . On October 29th, 2024, Volaris initiated direct flights to Las Vegas . This flight operates three times a week and

30340-444: The same layout as Concourse A with sitting areas, food stands, and duty-free shops. This concourse features eight gates: gates 10-14 are located on the top floor and are equipped with jet bridges, while gates 15-18 are located on the ground floor, where passengers board their aircraft directly from the apron. Airlines operating from Concourse B include Aeromexico, Viva Aerobus , Volaris, and from 2024, American Eagle . The top floor of

30525-424: The settlement of the international border, both of which specified that the middle of the Rio Grande was the border, irrespective of any alterations in the channels or banks. The Rio Grande shifted south between 1852 and 1868, with the most radical shift in the river occurring after a flood in 1864. By 1873 the moving river-center border had cut off approximately 2.4 square kilometers (590 acres) of Mexican territory in

30710-549: The six Mexican states that border the U.S.: Baja California , Chihuahua , Coahuila , Nuevo León , Sonora and Tamaulipas . It is the tenth-longest border between two countries in the world. The total length of the continental border is 3,145 kilometers (1,954 miles). From the Gulf of Mexico, it follows the course of the Rio Grande (Río Bravo del Norte) to the border crossing at Ciudad Juárez, Chihuahua , and El Paso, Texas . Westward from El Paso–Juárez , it crosses vast tracts of

30895-430: 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 ) –

31080-540: The terminal houses international arrivals corridors and the entrance vestibule for passengers coming from the Cross Border Xpress (CBX) terminal in San Diego. The vestibule leads to a Mexican immigration and customs facility and a check-in area for international passengers. The Cross Border Xpress (CBX), also known as the Cross-Border Terminal, is a 4,200 square metres (45,000 sq ft) terminal located in southern San Diego , California , adjacent to

31265-417: The tourist aspect of the city, it is damaging to low-income residents that will no longer be able to afford the cost of living in Tijuana. Tijuana is home to many deportees from the U.S., many who have lost everything and do not have an income to rely on and are now in a new city in which they have to quickly adapt in order to survive. San Diego developers would bring many benefits to Tijuana, but deportees and

31450-434: 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

31635-507: The two nations, "along the deepest channel" (also known as the thalweg )—a distance of 2,020 km (1,255 mi) to its mouth at the Gulf of Mexico. The Rio Grande frequently meanders along the Texas–Mexico border. As a result, the U.S. and Mexico have a treaty by which the Rio Grande is maintained as the border, with new cut-offs and islands being transferred to the other nation as necessary. The Boundary Treaty of 1970 between Mexico and

31820-535: The two nations, and provide for flood control and water sanitation. Once viewed as a model of international cooperation, in recent decades the IBWC has been heavily criticized as an institutional anachronism, by-passed by modern social, environmental and political issues. In particular, jurisdictional issues regarding water rights in the Rio Grande Valley have continued to cause tension between farmers along

32005-422: 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

32190-524: 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

32375-580: The world. The Mexico–U.S. border begins at the Initial Point of Boundary Between U.S. and Mexico , which is set one marine league (three nautical miles ) south of the southernmost point of San Diego Bay . The border then proceeds for 227 km (141 mi) in a straight line towards the confluence of the Colorado River and Gila River . The border continues southwards along the Colorado River for 39 km (24 mi), until it reaches

32560-540: 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

32745-508: 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

32930-415: Was created in 1924 with its primary mission to detect and prevent the illegal entry of immigrants into the U.S. Together with other law enforcement officers, the Border Patrol maintains the U.S.' borderlands—regulating the flow of legal immigration and goods while patrolling for undocumented migrants and trafficking of people and contraband. The present strategy to enforce migration along the U.S.–Mexico border

33115-639: 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 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

33300-519: Was part of New Spain . In the early 19th century, the U.S. bought the lands known as the Louisiana Purchase from France and began to expand steadily westward. After the 1803 Louisiana Purchase, the border between the U.S. and New Spain was not clearly defined. The border was established in the 1819 Adams–Onís Treaty between the U.S. and Spain, which specified northern and eastern borders. Mexico gained its independence from Spain, and

33485-508: 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

33670-409: 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

33855-430: 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 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

34040-606: 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

34225-656: 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
