9869-424: The Spanish-speaking world, Spanish is called not only español but also castellano (Castilian), the language from the Kingdom of Castile , contrasting it with other languages spoken in Spain such as Galician , Basque , Asturian , Catalan/Valencian , Aragonese , Occitan and other minor languages. The Spanish Constitution of 1978 uses the term castellano to define the official language of
10008-568: The T-33 was well liked by most FAM pilots and became a huge success as a patrol and interceptor aircraft. During the seventies and early eighties an additional 20 or more T-33s were procured by the FAM to replace aircraft lost in accidents and to increase the size of the fleet after the retirement of the Vampires. In 1982, the FAM received 12 Northrop F-5E/F Tiger II jets (10 F-5Es and 2 F-5Fs). The F-5 gave Mexico its first supersonic platform and saw
10147-502: The U.S. population were of Hispanic or Hispanic American by origin. In turn, 41.8 million people in the United States aged five or older speak Spanish at home, or about 13% of the population. Spanish predominates in the unincorporated territory of Puerto Rico , where it is also an official language along with English. Spanish is by far the most common second language in the country, with over 50 million total speakers if non-native or second-language speakers are included. While English
10286-457: The administration of Ferdinand Marcos two months later. It remained an official language until the ratification of the present constitution in 1987, in which it was re-designated as a voluntary and optional auxiliary language. Additionally, the constitution, in its Article XIV, stipulates that the Government shall provide the people of the Philippines with a Spanish-language translation of
10425-502: The air force's remaining airplanes consisted of worn and shot Bristol F.2 Fighter , Bristol Boarhound , de Havilland DH-4B and Douglas O-2 C, a force that was not suitable to defeat Escobar's power. In this context, the Mexican government convinced the U.S. government to promote the peace south of its border and quickly make available twelve new OU-2M Corsair with the 400 hp Wasp engine, nine Douglas O-2 M, four Stearman C3 B and six Waco Taper Wings . Only two weeks after making
10564-527: The airspace assigned by the Air Force Command. The primary purpose of Air Bases is to conduct and support military aerial operations, ensuring the security and defense of the designated airspace, and contributing to internal security in accordance with directives from the Zone, Air Region, Air Force Command, and Ministry of Defense. The Mexican Air Force comprises 18 Air Force Bases, each associated with
10703-584: The airspaces over one or more contiguous Zones or federal entities. In each Air Region, the Air Force provides security and defense, and address internal security matters in coordination with other Armed Forces or any federal institution. Each Air Region is composed of Headquarters, Air Force Bases, Air Force Stations, and other organizations. The Air Force divides the country's territory into four regions: Northwestern ( Mexicali , Baja California ), Northeastern ( Chihuahua , Chihuahua ), Central ( Mexico City ) and Southeastern ( Tuxtla Gutiérrez , Chiapas ); each region
10842-527: The army in 1918, and retrofitted them to make them safer, denominating them as the DH.4B. In 1919, the DH-4B was standardised by the US Post Office, being modified to be flown from the rear cockpit with a 400 lb (180 kg) watertight mail compartment replacing the forward cockpit. The airmail DH-4B were later modified with revised landing gear and an enlarged rudder . DH-4s were used to establish
10981-409: The assertive use of air superiority alone. On December 7, 1923, former President Adolfo de la Huerta launched a military coup ( delahuertista rebellion ) against the government of President Álvaro Obregón . The situation was extremely critical, because along with de la Huerta, about 60% of the army revolted, including various high-ranking generals across the country. The power tilted back in favor of
11120-622: The best of which was the 375 hp (280 kW) Rolls-Royce Eagle engine. The DH.4 first flew in August 1916 and it entered operational service in France on 6 March 1917 less than a year later. The majority were manufactured as general purpose two-seaters in the United States for the American expeditionary forces in France, becoming the only American made plane to see combat in WW1. Following
11259-517: The branches of aviation, general aviation tactics, meteorology , air navigation , air traffic control , radio communications and culture in general, along with approximately 250 hours of flight. During the first year, the training is theoretical. During the second year, Beechcraft Bonanza aircraft are used for flight instruction. During the third the cadets are trained Aermacchi SF260EU for aerobatics, and later on Pilatus PC-7 for advanced flight tactics, including combat. Within each of these stages,
11398-587: The cadets are trained in aerial acrobatics , stage tactical instrument flight, visual flying rules (VFR), radio operations, among others, which increase in complexity as the cadets' training progresses. The first female aviator to graduate as a pilot in the history of FAM, Andrea Cruz, became a cadet at the Military Aviation School in 2007. Military School of Air Force Specialist offers a comprehensive scholarship lasting three years for officer training meteorologists and flight control, obtaining at

The requirements are: In order to be admitted to any school of the Mexican Air Force Academy mentioned above, the applicant should also perform the following tests: physical, medical, cultural, and aviation psychology. In some cases, the psychological aeromedical 2nd level examination may also be required. Spanish language Spanish ( español ) or Castilian ( castellano )
11676-684: The classic hispanus or hispanicus took the suffix -one from Vulgar Latin , as happened with other words such as bretón (Breton) or sajón (Saxon). Like the other Romance languages , the Spanish language evolved from Vulgar Latin , which was brought to the Iberian Peninsula by the Romans during the Second Punic War , beginning in 210 BC. Several pre-Roman languages (also called Paleohispanic languages )—some distantly related to Latin as Indo-European languages , and some that are not related at all—were previously spoken in
11815-500: The consonant written b (a bilabial with plosive and fricative allophones). In modern Spanish, there is no difference between the pronunciation of orthographic b and v . Typical of Spanish (as also of neighboring Gascon extending as far north as the Gironde estuary , and found in a small area of Calabria ), attributed by some scholars to a Basque substratum was the mutation of Latin initial f into h- whenever it
11954-404: The country's constitution. In recent years changing attitudes among non-Spanish speaking Filipinos have helped spur a revival of the language, and starting in 2009 Spanish was reintroduced as part of the basic education curriculum in a number of public high schools, becoming the largest foreign language program offered by the public school system, with over 7,000 students studying the language in
12093-423: The crew members difficult, especially in combat with enemy fighters. There was also some controversy (especially in American service) that this placement of the fuel tank was inherently unsafe. In fact, most contemporary aircraft were prone to catching fire in the air. The fire hazard was reduced, however, when the pressurised fuel system was replaced by one using wind-driven fuel pumps late in 1917, although this
12232-515: The current air force. Its first commander was Lt. Alberto Salinas Carranza. When WWI Ace U.S. Colonel Ralph O'Neill was hired to head the restructuring of the Mexican Air Force in 1920, he reported to General Plutarco Elías Calles that most of the aircraft available had to be replaced. Until August 1920, the entire fleet consisted of 13 national made prototypes of mixed engine design. These were functional yet ill-equipped for battle, 4 being scout monoplanes. 5 others were in repair and over 20 more at
12371-462: The end of 1918. Following the end of the First World War, America had a large surplus of DH-4s, with the improved DH-4B becoming available, although none had been shipped to France. It was therefore decided that there was no point in returning aircraft across the Atlantic, so those remaining in France, together with other obsolete observation and trainer aircraft, were burned in what became known as
12510-538: The end of the Great War. One of the more elaborate modifications of the DH.4 was the adaption of the type as a seaplane. It was furnished with large floats , which were allegedly based upon the design of those used upon the German Hansa-Brandenburg W.29 seaplane. According to Bruce, while no such aircraft entered into operational service as a result of competition from other aircraft to perform
12649-410: The extreme age of the aircraft, the Mexican Air Force retired all but three F-5s in late 2017. In early 2019, the Mexican Air Force received repaired engines for their F-5 fighters, as part of an effort to return a handful of the aircraft to operational status. In early 2023, restoration work on F-5 airframes has begun with the intention to have a total of at least nine F-5s in active service. Because of
12788-620: The federal forces when the United States agreed to furnish the Mexican government with a fleet of new de Havilland DH-4B aircraft equipped with the Liberty motor, armed with Lewis and Vickers machine guns and able to carry bombs. The military coup was suffocated by February 1924. In 1925, due to the shortage of airplanes caused by World War I, Mexico set up the National Aviation Workshops ( TNCA ) to design and build its own airplanes and aeroengines. A territorial war
12927-683: The following table: Spanish is marked by palatalization of the Latin double consonants ( geminates ) nn and ll (thus Latin annum > Spanish año , and Latin anellum > Spanish anillo ). The consonant written u or v in Latin and pronounced [w] in Classical Latin had probably " fortified " to a bilabial fricative /β/ in Vulgar Latin. In early Spanish (but not in Catalan or Portuguese) it merged with
13066-573: The formation of Air Squadron 401. Since the 1980s the F-5 became the main Mexican fighter jet while the remaining operational T-33s were used for subsonic support and light attack roles. In 1983 one F-5E was lost in an accident that occurred during a target practice exercise in the state of Chihuahua . On January 1, 1994, the day the North American Free Trade Agreement (NAFTA) came into effect, hundreds of guerrillas from
13205-466: The former British colony of Belize (known until 1973 as British Honduras ) where English is the sole official language, according to the 2022 census, 54% of the total population are able to speak the language. Due to its proximity to Spanish-speaking countries and small existing native Spanish speaking minority, Trinidad and Tobago has implemented Spanish language teaching into its education system. The Trinidadian and Tobagonian government launched
13344-521: The fuel tank was positioned. While the crew arrangement provided good fields of view for both the pilot and observer; however, it had the noticeable downside of causing communication problems between the two crew members, particularly during combat situation, where the speaking tube that linked the two cockpits was of only limited use. On the majority of American-built aircraft, the pilot's seating and fuel tank arrangement were switched around; aviation author Peter M Bowers credits this change with improving
13483-673: The graduate level of lieutenant. His duties are to provide meteorological information and control of military or civil aircraft. Military School of the Air Forces specialists is an establishment of military education that has as its mission to train sergeants in seconds aviation maintenance, supply lines, electronic aviation and military aviation. The school is located in the St. Lucía military base. In this school, officers are trained as aviation maintenance specialists, aviation electronics specialists, weapons and air supply lines. To enter any of
13622-604: The grammar, dated 18 August 1492, Nebrija wrote that "... language was always the companion of empire." From the 16th century onwards, the language was taken to the Spanish-discovered America and the Spanish East Indies via Spanish colonization of America . Miguel de Cervantes , author of Don Quixote , is such a well-known reference in the world that Spanish is often called la lengua de Cervantes ("the language of Cervantes"). In
13761-594: The language is also known as Castilian ( castellano ). The group evolved from several dialects of Vulgar Latin in Iberia after the collapse of the Western Roman Empire in the 5th century. The oldest Latin texts with traces of Spanish come from mid-northern Iberia in the 9th century, and the first systematic written use of the language happened in Toledo , a prominent city of the Kingdom of Castile , in
13900-549: The language's hegemony in an intensely centralising Spanish state were established from the 18th century onward. Other European territories in which it is also widely spoken include Gibraltar and Andorra . Spanish is also spoken by immigrant communities in other European countries, such as the United Kingdom , France , Italy , and Germany . Spanish is an official language of the European Union . Today,
14039-557: The leader's command and with the massed defensive fire of the formation deterring attacks by enemy fighters. Despite heavy losses, 55 Squadron continued in operation, the only one of the day bombing squadrons in the Independent Force which did not have to temporarily stand down owing to aircrew losses. After the Armistice , the RAF formed No. 2 Communication Squadron , equipped with DH.4s to carry important passengers to and from
14178-469: The majority of frontline DH.4s by the end of 1917. However, this transition was greatly hindered as by January 1917, it had become clear that there was a chronic shortage of Rolls-Royce aero engines, and of the Eagle in particular; it has been claimed by Bruce that this shortfall was partially the result of protracted decision-making on the part of the Air Board. In response to the limited availability of
14317-694: The majority of the Spanish speakers live in Hispanic America . Nationally, Spanish is the official language—either de facto or de jure —of Argentina , Bolivia (co-official with 36 indigenous languages), Chile , Colombia , Costa Rica , Cuba , Dominican Republic , Ecuador , El Salvador , Guatemala , Honduras , Mexico (co-official with 63 indigenous languages), Nicaragua , Panama , Paraguay (co-official with Guaraní ), Peru (co-official with Quechua , Aymara , and "the other indigenous languages"), Puerto Rico (co-official with English), Uruguay , and Venezuela . Spanish language has
14456-468: The mobilization of American industry to set about the production of contemporary combat aircraft. As there were no suitable aircraft domestically, a technical commission, known as the Bolling Commission, was dispatched to Europe to seek out the best available combat aircraft and to make arrangements to enable their production to be established in the United States. As a result of the efforts of
14595-734: The northwest of the African mainland. The Spanish spoken in the Canary Islands traces its origins back to the Castilian conquest in the 15th century , and, in addition to a resemblance to Western Andalusian speech patterns, it also features strong influence from the Spanish varieties spoken in the Americas, which in turn have also been influenced historically by Canarian Spanish. The Spanish spoken in North Africa by native bilingual speakers of Arabic or Berber who also speak Spanish as
14734-466: The ongoing Mexican Drug War , increasing importance has been placed on acquiring airborne surveillance platforms, UAVs, light attack aircraft, helicopters and rapid troop transports. On 21 February 2021, a Learjet 45XR operated by the Mexican Air Force crashed while taking off from El Lencero Airport in Veracruz , killing all six people on board. Air Force Regions ( Spanish : Región Aérea ) are
14873-654: The other hand, currently uses the term español in its publications. However, from 1713 to 1923, it called the language castellano . The Diccionario panhispánico de dudas (a language guide published by the Royal Spanish Academy) states that, although the Royal Spanish Academy prefers to use the term español in its publications when referring to the Spanish language, both terms— español and castellano —are regarded as synonymous and equally valid. The term castellano
15012-427: The performance of the Eagle engine, which remained the preferred options despite the persistent supply constraints. At the time of entry of the United States into the First World War on 6 April 1917, the aviation section of the U.S. Signal Corps was unprepared, not being equipped with any aircraft suitable for combat. However, considerable optimism and energy was put into addressing this identified need, leading to
15151-453: The pilot's safety in the event of a crash, as well as allowing for better communication with the observer. The DH.4 was armed with a single forward-firing synchronised Vickers machine gun along with either one or two .303 in (7.7 mm) Lewis guns fitted on a Scarff ring fired by the observer. In terms of bomb load, it accommodate a maximum payload of 460 lb (210 kg), which could be mounted upon external racks. Throughout
15290-533: The population. Many northern Moroccans have rudimentary knowledge of Spanish, with Spanish being particularly significant in areas adjacent to Ceuta and Melilla. Spanish also has a presence in the education system of the country (through either selected education centers implementing Spain's education system, primarily located in the North, or the availability of Spanish as foreign language subject in secondary education). In Western Sahara , formerly Spanish Sahara ,
15429-463: The presidency to General Calles, General Arnulfo R. Gómez launched a military coup against both Obregón and Calles. His command posts were located in the cities of Puebla and Veracruz , where he led approximately 200 federal deserters, ammunition and weapons. The air force played a key role in their defeat. Then, on March 3, 1929, a serious military coup took place, led by General José Gonzalo Escobar and heeded by various other generals. In these days,
15568-695: The previously unknown Zapatista Army of National Liberation (EZLN) occupied several towns and cities in the southern state of Chiapas . The FAM was mobilized to support Army units, sending almost every available helicopter to the territory of operations. Units involved included the recently formed 214th and 215th Special Operations Squadrons, equipped with a mix of Bell 212 assault- and MD.530F scout helicopters. Up to 40 helicopters were deployed to support an initial deployment of 10,000 ground troops. Bell 212s were armed in two configurations: for fire support with twin MAG 7.62-mm gun pods and cabin-mounted GPMGs; or as gunship, with LAU-32 70-mm rocket launchers,
15707-464: The prototype DH.4 made its first flight, powered by a prototype 230 hp (170 kW) BHP engine. Initial flight tests revealed it to have favourable handling and performance. The Central Flying School (CFS) conducted early evaluation flights using the prototype, leading to it producing a favourable report on the aircraft, observing good stability in flight, light flying controls and its relatively comfortable crew positions. During its flights with
15846-561: The request, the U.S. government agreed, and several Mexican pilots travelled to Brownsville, Texas , and New York to pick up the new aircraft. The key victory was decided in late March 1929 at the Battle of Jiménez , Chihuahua , where after several days of air raids, Escobar was defeated by General Calles, taking about 6000 prisoners. This rebellion was quite serious, since a third of the officials and nearly 30,000 soldiers rebelled; in two months, more than 2000 men had been killed. In May 1938,
15985-400: The requirements of military air operations and addressing their own living and operational necessities. They may have assigned crews and aircraft in support or transit, over which they exert technical, administrative, and disciplinary control for the duration of their stay. Air Force ranks are the same as in Mexico's Army, with the exception of generals. A national commander under the orders of
16124-517: The role, a number of DH.4 seaplanes were produced for trial purposes at Felixstowe and were successfully flown. The DH.4 entered service with the RFC in January 1917, first being used by No. 55 Squadron . More squadrons were equipped with the type to increase the bombing capacity of the RFC, with two squadrons re-equipping in May, and a total of six squadrons by the end of the year. During late 1917,
16263-412: The service's own requirements, for evaluation purposes; however, according to Bruce, it is unlikely that the second of these was ever constructed. Following trials with the first of these prototypes, orders were placed for the production of DH.4s to equip the Royal Naval Air Service . During late 1916, the first order for 50 DH.4s, powered by 250 hp (190 kW) Eagle III engines, was received from
16402-537: The term español (Spanish). According to the Royal Spanish Academy, español derives from the Occitan word espaignol and that, in turn, derives from the Vulgar Latin * hispaniolus ('of Hispania'). Hispania was the Roman name for the entire Iberian Peninsula . There are other hypotheses apart from the one suggested by the Royal Spanish Academy. Spanish philologist Ramón Menéndez Pidal suggested that
16541-406: The term "Fuerza Aérea Mexicana" (FAM) naming the organization as such. The next step was the formation of classified fighter, bombing, observation and reconnaissance squadrons, as well as the decentralization of Air Force units throughout the country at strategic bases. O'Neill then set to work with his co-instructors German Fritz Bieler and Frenchman Joe Ben Lievre, using the first intercom known as
16680-444: The theories of Ramón Menéndez Pidal , local sociolects of Vulgar Latin evolved into Spanish, in the north of Iberia, in an area centered in the city of Burgos , and this dialect was later brought to the city of Toledo , where the written standard of Spanish was first developed, in the 13th century. In this formative stage, Spanish developed a strongly differing variant from its close cousin, Leonese , and, according to some authors,
16819-768: The third most used language on the Internet , after English and Chinese. Spanish is the official language of Spain . Upon the emergence of the Castilian Crown as the dominant power in the Iberian Peninsula by the end of the Middle Ages, the Romance vernacular associated with this polity became increasingly used in instances of prestige and influence, and the distinction between "Castilian" and "Spanish" started to become blurred. Hard policies imposing
16958-413: The type into the early 1930s. The DH.4 was designed by Geoffrey de Havilland as a light two-seat combat aircraft, intended to perform both day bomber and aerial reconnaissance missions. The intention was for it to be powered by the newly developed 160 hp (120 kW) Beardmore Halford Pullinger (BHP) engine. The DH.4 was developed in parallel to the rival Bristol Fighter . During August 1916,
17097-508: The type's production life, a number of alterations to the armaments, such as the ergonomics of the observer's Lewis gun and the installation of an additional Vickers gun, were implemented. A pair of DH.4s were outfitted with COW 37 mm guns for experimental purposes, but the war came to a close prior to firing trials being conducted. All armaments would typically be removed from those DH.4s that were used by civil operators, including ex-military aircraft that were sold on in great numbers following
17236-511: The underside of the tail area was covered by a 3mm plywood skin; this construction led to the fuselage being both strong and lightweight, heavily contributing to cross-bracing only being used for the four bays directly behind the rear cockpit. The nose of the aircraft was considerably longer than necessary, the cowling having been originally designed to accommodate the Beardmore Halford Pullinger (BHP) engine, rather than
17375-452: The upper wing. An unusual modification featuring on a small proportion of production DH.4s was the inversion of the engine, a design change that had been implemented in order to better accommodate the relatively-tall Ricardo-Halford-Armstrong (RHA) supercharged engine, which would otherwise unduly obstruct the pilot's forward field of view. The DH.4 was operated by a crew of two, who were accommodated in widely spaced cockpits, between which
17514-571: The uptake of the type by the RFC was accelerated due to a desire to launch retaliatory bombing raids upon Germany following such attacks having been conducted against the British mainland. While Russia had been an early customer for the DH.4, having ordered 50 of the type in September 1917, the Russian and British governments subsequently agreed to delay the former's deliveries, instead diverting those aircraft to RFC squadrons in France. As well as
17653-585: The whole of Spain, in contrast to las demás lenguas españolas (lit. "the other Spanish languages "). Article III reads as follows: El castellano es la lengua española oficial del Estado. ... Las demás lenguas españolas serán también oficiales en las respectivas Comunidades Autónomas... Castilian is the official Spanish language of the State. ... The other Spanish languages shall also be official in their respective Autonomous Communities... The Royal Spanish Academy ( Real Academia Española ), on
17792-582: The world. Spanish is well represented in the humanities and social sciences . Spanish is also the third most used language on the internet by number of users after English and Chinese and the second most used language by number of websites after English. Spanish is used as an official language by many international organizations , including the United Nations , European Union , Organization of American States , Union of South American Nations , Community of Latin American and Caribbean States , African Union , among others. In Spain and some other parts of
17931-515: The years until finally, in 1959 it joined the military school of meteorology, mechanics and aviation specialists, forming the leading campus in military aviation education: 'El Colegio del Aire' (Air Force Academy), which since September 9, 1959, has guided the formation of Air Force officers. The Air Force Academy is an all academic institution of the Mexican Air Force and comprises four schools: 'Military Aviation School', 'Maintenance and Supply Military School', 'Air Force Military Specialist School', and
18070-594: Was a 400 hp (300 kW) Liberty L-12 and it was fitted with two forward-firing .30 in (7.62 mm) synchronized Marlin-Rockwell M1917 (a development of the Colt-Browning ) machine guns in the nose and two .30 in (7.62 mm) Lewis guns in the rear and could carry 322 lb (146 kg) of bombs. it could also be equipped with various radios like the SCR-68 for artillery spotting missions. The heavier engine reduced performance compared with
18209-634: Was developed in the cities of Toledo , in the 13th to 16th centuries, and Madrid , from the 1570s. The development of the Spanish sound system from that of Vulgar Latin exhibits most of the changes that are typical of Western Romance languages , including lenition of intervocalic consonants (thus Latin vīta > Spanish vida ). The diphthongization of Latin stressed short e and o —which occurred in open syllables in French and Italian, but not at all in Catalan or Portuguese—is found in both open and closed syllables in Spanish, as shown in
18348-622: Was distinguished by a heavy Basque influence (see Iberian Romance languages ). This distinctive dialect spread to southern Spain with the advance of the Reconquista , and meanwhile gathered a sizable lexical influence from the Arabic of Al-Andalus , much of it indirectly, through the Romance Mozarabic dialects (some 4,000 Arabic -derived words, make up around 8% of the language today). The written standard for this new language
18487-713: Was followed by a vowel that did not diphthongize. The h- , still preserved in spelling, is now silent in most varieties of the language, although in some Andalusian and Caribbean dialects, it is still aspirated in some words. Because of borrowings from Latin and neighboring Romance languages, there are many f -/ h - doublets in modern Spanish: Fernando and Hernando (both Spanish for "Ferdinand"), ferrero and herrero (both Spanish for "smith"), fierro and hierro (both Spanish for "iron"), and fondo and hondo (both words pertaining to depth in Spanish, though fondo means "bottom", while hondo means "deep"); additionally, hacer ("to make")
18626-528: Was nicknamed "The Flying Avocado " by Mexican flight crews due to the ovoid shape of its fuselage and the dark green night camouflage adopted by its first units. The Vampires were not popular with Mexican fighter pilots because of its lack of ejection seats. The FAM finally retired them in 1970. The Mexican Vampires were initially complemented by 15 Lockheed T-33 Shooting Star subsonic fighter aircraft received also in late 1961. Because of its more modern design, an ejection seat system and several other attributes,
18765-441: Was not initially adopted by American-built aircraft. The otherwise inferior DH.9 brought the pilot and observer closer together by placing the fuel tank in the usual place, between the pilot and the engine. Despite its success, numbers in service with the RFC actually started to decline from spring 1918, mainly due to a shortage of engines, and production switched to the DH.9, which turned out to be disappointing, being inferior to
18904-577: Was provided with a 0.303 in (7.7 mm) Lewis gun mounted upon a Scarff ring . Production of the DH.4 was performed by a variety of companies beyond Airco themselves; these included F.W. Berwick and Co, Glendower Aircraft Company, Palladium Autocars, Vulcan Motor and Engineering, and the Westland Aircraft Works . By the end of production, a total of 1,449 aircraft (from orders for 1,700 aircraft) were constructed in Britain for
19043-462: Was revoked by Michel Temer after the impeachment of Dilma Rousseff . In many border towns and villages along Paraguay and Uruguay, a mixed language known as Portuñol is spoken. Equatorial Guinea is the only Spanish-speaking country located entirely in Africa, with the language introduced during the Spanish colonial period . Enshrined in the constitution as an official language (alongside French and Portuguese), Spanish features prominently in
19182-646: Was that of the Sonora Yaqui Indians who demanded by force that previous territorial treaties were implemented. The conflict lasted from 1926 to 1927, and it came to an end when a new treaty was implemented. When President Plutarco Elías Calles pushed for the creation of the 'Mexican Apostolic Catholic Church', independent of Rome, it unleashed a widespread religious war known as the Cristero War . This long civil war lasted from 1926 to 1929. In May 1927, while General Obregón seemed keen to impose
19321-423: Was the spearhead of operation "Arco Iris" (Rainbow) to re-take several towns that had fallen under rebel control in January 1994. The new militarized Defenders came armed with M2AC machine-guns and LAU-68A 70-mm rocket launchers. Three additional units were ordered in 1996 and delivered as attrition replacements in March 1998. Black Hawks wore 1191 to 1194 serials and are being used for special operations. Although
