An IATA airport code , also known as an IATA location identifier , IATA station code , or simply a location identifier , is a three-letter geocode designating many airports and metropolitan areas around the world, defined by the International Air Transport Association (IATA). The characters prominently displayed on baggage tags attached at airport check-in desks are an example of a way these codes are used.
151-574: Kirtland Air Force Base ( IATA : ABQ , ICAO : KABQ ) is a United States Air Force base. It is located in the southeast quadrant of the Albuquerque, New Mexico , urban area, adjacent to the Albuquerque International Sunport . The base was named for the early Army aviator Col. Roy C. Kirtland . The military and the international airport share the same runways, making ABQ a joint civil-military airport. Kirtland AFB
302-551: A B-29 Superfortress base in support of the incendiary bombing raids on Japan. In March 1945, Kirtland Field was converted into a Superfortress base in a matter of only 45 days after its assignment to the Second Air Force . The Second Air Force, operating under the Continental Air Forces , concentrated on training for heavy and very heavy bombers during the war. Kirtland Field was one of six stations in

On 16 July 1945, at Kirtland Field, two B-29 Superfortress observation planes had set out early in the morning with instructions from Oppenheimer to steer a course at least 15 miles west of the atomic detonation point, Trinity Site . Because of thunderstorms, the planes dropped from 23,000 to 18,000 feet before circling the Trinity Site during the first atomic bomb detonation . While "The Gadget" underwent field-testing at Trinity,
1510-461: A major range located between the neighboring village, Los Lunas and the Rio Puerco. Contracts for day and night bombing targets on the ranges were let during January 1942, and access roads to the targets were constructed. Bomb ranges numbered 2,450 square miles on ranch and Indian reservation land by the end of 1942. At that time, a total of 24 targets, simulated cities and warships, were in use on

More people commuted longer hours to afford a home in more rural areas while earning larger salaries in the urban areas. Speculators bought houses, expecting to make a huge profit in months, then rolling it over by buying more properties. Mortgage companies were compliant, as people assumed prices would keep rising. The bubble burst in 2007–8 as prices began to crash. Hundreds of billions in property values vanished and foreclosures soared, as financial institutions and investors were badly hurt. In

The original airport in Nashville, Tennessee, was built in 1936 as part of the Works Progress Administration and called Berry Field with the designation, BNA. A new facility known as Nashville International Airport was built in 1987 but still uses BNA. This
1963-469: A part of Mexico. In 1846, the total settler population of the western part of the old Alta California had been estimated to be no more than 8,000, plus about 100,000 Native Americans, down from about 300,000 before Hispanic settlement in 1769. In 1848, only one week before the official American annexation of the area, gold was discovered in California, this being an event which was to forever alter both

Once the state's Constitutional Convention had finalized its state constitution, it applied to the U.S. Congress for admission to statehood . On September 9, 1850, as part of the Compromise of 1850 , California became a free state and September 9 a state holiday . During the American Civil War (1861–1865), California sent gold shipments eastward to Washington in support of
2416-479: A significant USAF center for R&D. What began as a 2,000-acre air base has grown into a 51,800-plus-acre facility. Kirtland Air Force Base's beginnings stem from three private airfields of 1928 to 1939 and are similar to that of other installations choosing to adapt existing runways and hangars for military use. In 1928, two Santa Fe Railroad employees working with the town of Albuquerque , graded two runways on East Mesa with one approximately 5,300 feet long and
2567-612: A state Constitutional Convention was first held in Monterey. Among the first tasks of the convention was a decision on a location for the new state capital. The first full legislative sessions were held in San Jose (1850–1851). Subsequent locations included Vallejo (1852–1853), and nearby Benicia (1853–1854); these locations eventually proved to be inadequate as well. The capital has been located in Sacramento since 1854 with only

Additionally the 150th Special Operations Wing of the New Mexico Air National Guard , an Air Combat Command (ACC)-gained unit, is also garrisoned at Kirtland. Kirtland Air Force Base was named for Colonel Roy C. Kirtland (1874–1941) in February 1942. Colonel Kirtland learned to fly in 1911 in one of the first Wright airplanes at Dayton, Ohio . During World War I , he organized and commanded
3171-554: Is available. However, many railway administrations have their own list of codes for their stations, such as the list of Amtrak station codes . Airport codes arose out of the convenience that the practice brought pilots for location identification in the 1930s. Initially, pilots in the United States used the two-letter code from the National Weather Service (NWS) for identifying cities. This system became unmanageable for cities and towns without an NWS identifier, and

By the end of the expedition in 1770, they would establish the Presidio of Monterey and Mission San Carlos Borromeo de Carmelo on Monterey Bay. After the Portolà expedition, Spanish missionaries led by Father-President Serra set out to establish 21 Spanish missions of California along El Camino Real ("The Royal Road") and along
6493-774: The Route 66 . From 1900 to 1965, the population grew from fewer than one million to the greatest in the Union. In 1940, the Census Bureau reported California's population as 6% Hispanic, 2.4% Asian, and 90% non-Hispanic white. To meet the population's needs, engineering feats like the California and Los Angeles Aqueducts ; the Oroville and Shasta Dams ; and the Bay and Golden Gate Bridges were built. The state government adopted

New construction projects began early in 1942, adding offices and housing quarters, ordnance storage, a photography lab, flightline buildings, and maintenance hangars. The base undertook paving and lighting of aircraft parking spaces, and scheduled the building of additional runways and taxiways. Students began training on twin-engine Beechcraft AT-11 Kansan bomber trainers. By January 1942, there were 50 aircraft on base, in addition to 28 B-18A Bolo bombers used for training. Eventually, about 150 AT-11s served
10721-440: The airport itself instead of the city it serves, while another code is reserved which refers to the city itself which can be used to search for flights to any of its airports. For instance: Or using a code for the city in one of the major airports and then assigning another code to another airport: When different cities with the same name each have an airport, they need to be assigned different codes. Examples include: Sometimes,
10872-418: The airport's former name, such as Orlando International Airport 's MCO (for Mc C o y Air Force Base), or Chicago's O'Hare International Airport , which is coded ORD for its original name: Or char d Field. In rare cases, the code comes from the airport's unofficial name, such as Kahului Airport 's OGG (for local aviation pioneer Jimmy H ogg ). In large metropolitan areas, airport codes are often named after
11023-711: The arrival of 45 women on base. WAAC quarters built at Kirtland Field included barracks, a day room, beauty shop, and supply room. A WAAC open house for the new post was held in August 1943 and several hundred men with their wives and families attended. Initially, most WAACs and WACs worked as file clerks, typists, stenographers, or motor pool drivers. Gradually, their jobs grew more technical as positions were created for weather forecasters, parachute riggers, radio operators and repair specialists, sheet metal workers, bombsight maintenance specialists, control tower operators, and cryptographers. In August 1943, Kirtland Field became host to
11174-505: The base was activated. Its purpose was to train air and ground crews for reconnaissance and bombing duty on Boeing B-17 "Flying Fortresses" before deployment to Clark Field in the Philippine Islands . The 19th Bombardment Group became the most famous bomber unit of World War II for its part in the strategic campaign against Japan. The 30th, 32nd, and 93rd Bombardment Squadrons and the 38th Reconnaissance Squadron were assigned to
11325-670: The base was called the Eagle Nest Flight Center. Using Link Trainers and B-24 training aircraft, the TWA instructors trained more than 1,100 pilots and crewmen during the eight months the company operated the school. On 7 February 1942, the U.S. Army transferred the training function from TWA back to the USAAF, and the school was redesignated the Combat Crew Training School. The Air Corps Ferrying Command
11476-419: The base's fate in the postwar economy. To the east of the air base, at Oxnard Field, the U.S. Army also acquired 1,100 acres of land to develop a school for aircraft mechanics. An Air Depot Training Station, it was unofficially referred to as " Sandia Base ". After various other incarnations—as a convalescent center and aircraft burial ground—Sandia Base became the precursor to Sandia National Laboratories when
11627-454: The best land in the state, were secularized by 1834 and became the property of the Mexican government. The governor granted many square leagues of land to others with political influence. These huge ranchos or cattle ranches emerged as the dominant institutions of Mexican California. The ranchos developed under ownership by Californios (Hispanics native of California) who traded cowhides and tallow with Boston merchants. Beef did not become
11778-464: The best route to follow, which became known as "Marsh's route". His letters were read, reread, passed around, and printed in newspapers throughout the country, and started the first wagon trains rolling to California. After ushering in the period of organized emigration to California, Marsh became involved in a military battle between the much-hated Mexican general, Manuel Micheltorena and the California governor he had replaced, Juan Bautista Alvarado. At
11929-502: The code SHA, while the newer Shanghai–Pudong adopted PVG. The opposite was true for Berlin : the airport Berlin–Tegel used the code TXL, while its smaller counterpart Berlin–Schönefeld used SXF; the Berlin Brandenburg Airport has the airport code BER, which is also part of its branding. The airports of Hamburg (HAM) and Hannover (HAJ) are less than 100 nautical miles (190 km) apart and therefore share
12080-405: The command of Lt. Colonel Eugene Eubank, the 19th Bombardment Group focused on precision, high-altitude, and formation flying. They also flew mock attacks on New Mexico villages and ranches. Eubank was known for being a taskmaster, demanding that his pilots gain extensive cockpit experience and that the men cross-train as navigators and bombardiers. As such, it was purported that every B-17 flight had
12231-551: The conquest include the Battle of San Pasqual and the Battle of Dominguez Rancho in Southern California, as well as the Battle of Olómpali and the Battle of Santa Clara in Northern California. After a series of defensive battles in the south, the Treaty of Cahuenga was signed by the Californios on January 13, 1847, securing a censure and establishing de facto American control in California. Following
12382-535: The deadliest in U.S. history. Although air pollution has been reduced, health problems associated with pollution continue. Brown haze known as " smog " has been substantially abated after federal and state restrictions on automobile exhaust. An energy crisis in 2001 led to rolling blackouts , soaring power rates, and the importation of electricity from neighboring states. Southern California Edison and Pacific Gas and Electric Company came under heavy criticism. Housing prices in urban areas continued to increase;
12533-549: The difficulty was in housing the students because base quarters were not finished. Consequently, they doubled up in the barracks. The first contingent of B-24 trainees arrived in Albuquerque on 19 June 1941. The facility was officially titled the Air Corps Ferrying Command Four-Engine Transition School but was unofficially referred to as the "Four-Engine School" or "Jack Frye School"—for the president of TWA. Its location on
12684-482: The end of 1928. The airfield soon drew business from private flyers, as well as Transcontinental Air Transport (TAT) and Western Air Express (WAE), commercial airlines that set up operations at the new airport. The city's viability as a crossroad of air traffic in the Southwest was confirmed by this early success. As the 1920s closed, the two airlines initiated competitive passenger, mail, and cargo service between
12835-934: The end. Examples include: A lot of minor airfields without scheduled passenger traffic have ICAO codes but not IATA codes, since the four letter codes allow more number of codes, and IATA codes are mainly used for passenger services such as tickets, and ICAO codes by pilots. In the US, such airfields use FAA codes instead of ICAO. There are airports with scheduled service for which there are ICAO codes but not IATA codes, such as Nkhotakota Airport/Tangole Airport in Malawi or Chōfu Airport in Tokyo, Japan. There are also several minor airports in Russia (e.g., Omsukchan Airport ) which lack IATA codes and instead use internal Russian codes for booking. Flights to these airports cannot be booked through
12986-540: The fall of 1941, Major General Arnold moved the military's bombardier school from Louisiana to Albuquerque for two reasons—good weather and the availability of vacant land on which to build bombing ranges. It was proclaimed the "World’s First Bombardier School", and on 24 December 1941 it was officially designated an Army Air Forces Advanced Flying School under the USAAF Western Flying Training Command. The 56th and 88th School Squadrons,
13137-621: The ferrying of men and material to various field sites. From Kirtland Field, Manhattan Project scientists were flown back and forth to Wendover Army Air Base for testing in a disguised "Green Hornet" aircraft. Members of the USAAF made similar trips from Wendover through Albuquerque to Los Alamos. A special Manhattan Engineer District, Military Police unit was located at Kirtland Field to guard facilities used to load Los Alamos–assembled ordnance and test shapes on Silverplate aircraft. The loading pit constructed at Kirtland Field, although primitive and manually operated, operated until December 1945, when
13288-557: The first three letters of the city in which it is located, for instance: The code may also be a combination of the letters in its name, such as: Sometimes the airport code reflects pronunciation, rather than spelling, namely: For many reasons, some airport codes do not fit the normal scheme described above. Some airports, for example, cross several municipalities or regions, and therefore, use codes derived from some of their letters, resulting in: Other airports—particularly those serving cities with multiple airports—have codes derived from
13439-535: The focus on atomic weapons, in early December 1946, Kirtland Field was again transferred, this time to the Air Materiel Command (AMC), specifically the Directorate, Research and Development, HQ, AMC. AMC was responsible for all USAF R&D, including atomic weapons. The transfer took place due to Kirtland Field's close proximity to Sandia Base and the Z Division. The AMC mission at Kirtland Field
13590-478: The following format: Most large airports in Canada have codes that begin with the letter "Y", although not all "Y" codes are Canadian (for example, YUM for Yuma, Arizona , and YNT for Yantai , China), and not all Canadian airports start with the letter "Y" (for example, ZBF for Bathurst, New Brunswick ). Many Canadian airports have a code that starts with W, X or Z, but none of these are major airports. When
13741-597: The form of " YYZ ", a song by the rock band Rush , which utilizes the Morse code signal as a musical motif. Some airports have started using their IATA codes as brand names , such as Calgary International Airport (YYC) and Vancouver International Airport (YVR). Numerous New Zealand airports use codes that contain the letter Z, to distinguish them from similar airport names in other countries. Examples include HLZ for Hamilton , ZQN for Queenstown , and WSZ for Westport . Predominantly, airport codes are named after
13892-626: The government to adequately sustain the populations living on them. As a result, settler colonialism was a calamity for indigenous people. Several scholars and Native American activists, including Benjamin Madley and Ed Castillo , have described the actions of the California government as a genocide , as well as the 40th governor of California Gavin Newsom . Benjamin Madley estimates that from 1846 to 1873, between 9,492 and 16,092 indigenous people were killed, including between 1,680 and 3,741 killed by
14043-411: The highest output of any U.S. state, and is led by its dairy , almonds , and grapes . With the busiest port in the country ( Los Angeles ), California plays a pivotal role in the global supply chain, hauling in about 40% of goods imported to the US. Notable contributions to popular culture , ranging from entertainment , sports , music , and fashion , have their origins in California. California
14194-410: The indigenous peoples developed complex forms of ecosystem management, including forest gardening to ensure the regular availability of food and medicinal plants . This was a form of sustainable agriculture . To mitigate destructive large wildfires from ravaging the natural environment, indigenous peoples developed a practice of controlled burning . This practice was recognized for its benefits by
14345-470: The installation under SAC, and there was a return of personnel. Shortly thereafter, an "S-2 Section" was established on base and became responsible for the security of Kirtland Field and the "W-47 Project". The W-47 Project had been the wartime operation established at Wendover Army Air Base to train the 509th Composite Group to drop the atomic bombs on Hiroshima and Nagasaki . In keeping with Kirtland Field's mission to assist Sandia Base's Z Division with
14496-572: The interior and north of California. The Anza expedition selected numerous sites for missions, presidios, and pueblos, which subsequently would be established by settlers. Gabriel Moraga , a member of the expedition, would also christen many of California's prominent rivers with their names in 1775–1776, such as the Sacramento River and the San Joaquin River . After the expedition, Gabriel's son, José Joaquín Moraga , would found
14647-487: The international air booking systems or have international luggage transferred there, and thus, they are booked instead through the airline or a domestic booking system. Several heliports in Greenland have 3-letter codes used internally which might be IATA codes for airports in faraway countries. There are several airports with scheduled service that have not been assigned ICAO codes that do have IATA codes, especially in
14798-531: The largest dam removal and river restoration project in US history was announced for the Klamath River , as a win for California tribes. Covering an area of 163,696 sq mi (423,970 km ), California is the third-largest state in the United States in area, after Alaska and Texas . California is one of the most geographically diverse states in the union and is often geographically bisected into two regions, Southern California , comprising
14949-541: The marriage of bombs and aircraft, the 509th Composite Group's Flight Test Section was transferred to Kirtland. As these arrangements were taking place, a new subgroup of the Manhattan Project at Los Alamos was being organized. Titled the Z Division for its chief, Dr. Jerrold Zacharias , a Los Alamos scientist from the Massachusetts Institute of Technology (MIT), the new group's mission
15100-490: The mid-1930s, Mayor Tingley, other city officials, and TWA management began to conceive of a municipal airport, the next necessary step in confirming Albuquerque's status as a "Crossroads of the Southwest." With the help of President Roosevelt's Works Progress Administration (WPA) funds, construction on a new airport was begun four miles west of Oxnard Field and completed in 1939, on the cusp of World War II . In January 1939, Major General Henry "Hap" Arnold, who became chief of
15251-844: The middle of the state lies the California Central Valley , bounded by the Sierra Nevada in the east, the coastal mountain ranges in the west, the Cascade Range to the north and by the Tehachapi Mountains in the south. The Central Valley is California's productive agricultural heartland. Divided in two by the Sacramento-San Joaquin River Delta , the northern portion, the Sacramento Valley serves as
15402-612: The name of the airport itself, for instance: This is also true with some cities with a single airport (even if there is more than one airport in the metropolitan area of said city), such as BDL for Hartford, Connecticut 's B ra dl ey International Airport or Baltimore's BWI, for B altimore/ W ashington I nternational Airport ; however, the latter also serves Washington, D.C. , alongside Dulles International Airport (IAD, for I nternational A irport D ulles) and Ronald Reagan Washington National Airport (DCA, for D istrict of C olumbia A irport). The code also sometimes comes from
15553-448: The new program came a push for development of a comprehensive organization, with training in navigation, bombing, personnel equipment, chemical warfare, physical training, synthetic training, and use of the gunnery range. A primary mission for Kirtland Field was recorded in the September 1946 narrative history: "[To] provide aerial and ground functioning testing facilities and conduct functional tests on all equipment and materiel related to
15704-399: The new school from advanced twin-engine training schools. Instruction covered day and night navigation and instrument flying, formation and altitude flying, comprehensive ground schoolwork, engineering, radio, meteorology, weather flying, first aid and oxygen training, as well as a course on the duties of an airplane commander. A school for navigation was also established at Kirtland Field in
15855-544: The nuclear components for the bombs and the active materials were being sent piecemeal to Tinian . Shortly before the bomb testing at the Trinity site, components of Little Boy were driven from Los Alamos to Kirtland Field and then flown to San Francisco . This included some of the U-235 . From San Francisco, they were transported to Hunters Point to board the cruiser USS Indianapolis , bound for Tinian. Following that,
16006-736: The official opening of Albuquerque Army Air Base. The first buildings on the installation were simple wood-frame structures constructed quickly in order to fulfill the country's urgent need for trained pilots to fight the war. Most of the buildings were Theater of Operations construction while some were of the Mobilization type. The Mobilization type buildings included the station hospital, theater, chapel, and Link training buildings. During World War II there were three levels of pilot training: The Albuquerque Army Air Base provided advanced flying training in "AT" (advanced trainer) trainer aircraft and transition training in combat-ready aircraft, primarily
16157-416: The one they are located in: Other airport codes are of obscure origin, and each has its own peculiarities: In Asia, codes that do not correspond with their city's names include Niigata 's KIJ , Nanchang 's KHN and Pyongyang 's FNJ . EuroAirport Basel Mulhouse Freiburg , which serves three countries, has three airport codes: BSL, MLH, EAP. Some cities have a name in their respective language which
16308-487: The other just under 4,000 feet. Albuquerque Airport was wholly a private venture, irrespective of the town's involvement. Immediately following construction of the airport, other individuals and promoters became interested in Albuquerque as a crossroads location for southwestern air traffic. James G. Oxnard, a New York entrepreneur, bought Franklin's interest in Albuquerque Airport, expanding the facility toward
16459-414: The population of San Francisco increased from 500 to 150,000. The seat of government for California under Spanish and later Mexican rule had been located in Monterey from 1777 until 1845. Pio Pico, the last Mexican governor of Alta California, had briefly moved the capital to Los Angeles in 1845. The United States consulate had also been located in Monterey, under consul Thomas O. Larkin . In 1849,
16610-701: The possibility of an air base locating on the mesa, and through extensive negotiations with the AAC, succeeded in their efforts when the Army established an air base on the East Mesa in 1939. As of late 1939, Army and Navy pilots began using Oxnard Field for refueling and maintenance for a variety of military flights. Later that same year, the Army Air Corps leased 2,000 acres neighboring Albuquerque Airport, four miles west of Oxnard Field. The Army eventually condemned
16761-733: The pueblo of San Jose in 1777, making it the first civilian-established city in California. During this same period, sailors from the Russian Empire explored along the northern coast of California. In 1812, the Russian-American Company established a trading post and small fortification at Fort Ross on the North Coast . Fort Ross was primarily used to supply Russia's Alaskan colonies with food supplies. The settlement did not meet much success, failing to attract settlers or establish long term trade viability, and
16912-469: The races until the Indian race becomes extinct must be expected. While we cannot anticipate the result with but painful regret, the inevitable destiny of the race is beyond the power and wisdom of man to avert." As in other American states, indigenous peoples were forcibly removed from their lands by American settlers , like miners, ranchers, and farmers. Although California had entered the American union as
17063-412: The ranges. Bombardier school was 12 to 18 weeks during which a student dropped approximately 160 bombs; precise records were kept of hits and misses. The elimination rate for trainees was 12 percent, and upon graduation, a new bombardier was transferred to an operational training unit and trained for overseas duty. Albuquerque was an operational training facility, and the first class of 61 bombardiers from
17214-403: The region known as California , or Las Californias , grew. Eventually it included lands north of the peninsula, Alta California , part of which became the present-day U.S. state of California. A 2017 state legislative document states, "Numerous theories exist as to the origin and meaning of the word 'California, ' " and that all anyone knows is the name was added to a map by 1541 "presumably by
17365-506: The same first and middle letters, indicating that this rule might be followed only in Germany. Many cities retain historical names in their airport codes, even after having undergone an official name/spelling/transliteration change: Some airport codes are based on previous names associated with a present airport, often with a military heritage. These include: Some airports are named for an administrative division or nearby city, rather than
17516-428: The school. The USAAF established a new minimum proficiency standard for bombardier trainees in 1943. Trainees were required to hit their targets during at least 22 percent of their drops. Practice combat flying missions required continuous evasive action within a 10-mile radius of the intended target. The final approach was required to be straight, level and taking no longer than 60 seconds. The school taught bombardiers
17667-580: The small stockpile of atomic weapons parts. In the years after the war, Sandia Base boundaries would vastly expand to include the thousands of acres owned by the NMPG, which occupied much of the East Mesa. Base operations began to increase in June 1946 with the organization of a full-scale Ground Training Program and the arrival of the Special Ordnance Squadron and Special Transport Flight of
17818-654: The state as part of the Gold Rush or to seek work. Even though the Chinese proved indispensable in building the transcontinental railroad from California to Utah, perceived job competition with the Chinese led to anti-Chinese riots in the state, and eventually the US ended migration from China partially as a response to pressure from California with the 1882 Chinese Exclusion Act . Under earlier Spanish and Mexican rule, California's original native population had precipitously declined, above all, from Eurasian diseases to which
17969-465: The state on March 4, 2020, and remained in effect until Governor Gavin Newsom ended it in February 2023. A mandatory statewide stay-at-home order was issued on March 19, 2020, which was ended in January 2021. Cultural and language revitalization efforts among indigenous Californians have progressed among tribes as of 2022. Some land returns to indigenous stewardship have occurred. In 2022,
18120-430: The state results in climates that vary from moist temperate rainforest in the north to arid desert in the interior, as well as snowy alpine in the mountains . Droughts and wildfires are an ongoing issue. California's economy is the largest of any U.S. state, with a $ 4.0 trillion gross state product as of 2024 . It is the largest sub-national economy in the world. California's agricultural industry has
18271-515: The state's demographics and its finances. Soon afterward, a massive influx of immigration into the area resulted, as prospectors and miners arrived by the thousands. The population burgeoned with United States citizens, Europeans, Middle Easterns, Chinese and other immigrants during the great California gold rush . By the time of California's application for statehood in 1850, the settler population of California had multiplied to 100,000. By 1854, more than 300,000 settlers had come. Between 1847 and 1870,
18422-522: The state's name include CA, Cal., Calif., Califas , and US-CA . California was one of the most culturally and linguistically diverse areas in pre-Columbian North America . Historians generally agree that there were at least 300,000 people living in California prior to European colonization. The Indigenous peoples of California included more than 70 distinct ethnic groups , inhabiting environments ranging from mountains and deserts to islands and redwood forests. Living in these diverse geographic areas,
18573-620: The state, and develop a high-tech region, now known as Silicon Valley . As a result of this, California is a world center of the entertainment and music industries, of technology, engineering, and the aerospace industry, and as the US center of agricultural production. Just before the Dot Com Bust , California had the fifth-largest economy in the world. In the mid and late twentieth century, race-related incidents occurred. Tensions between police and African Americans, combined with unemployment and poverty in inner cities, led to riots, such as
18724-500: The station code of Malton, Mississauga , where it is located). YUL is used for Montréal–Trudeau (UL was the ID code for the beacon in the city of Kirkland , now the location of Montréal–Trudeau). While these codes make it difficult for the public to associate them with a particular Canadian city, some codes have become popular in usage despite their cryptic nature, particularly at the largest airports. Toronto's code has entered pop culture in
18875-484: The summer of 1943. The six-week navigation training course extended bombardier cadets’ schooling from 12 weeks to 18 weeks, qualifying them to serve as navigators as well. The navigation instructors were often recent combat veterans; the school combined regular bombardier missions to targets throughout New Mexico with navigational missions. A month later, headquarters of the 38th Flying Training Wing relocated from Roswell Army Airfield , New Mexico to Kirtland Field. One of
19026-421: The surplus planes sold some of the engines for commercial air transports, but by the end of the year, the remaining surplus planes were "chopped into sections and melted into ingots in a constantly burning smelter". This storage and recycling effort was the last of Albuquerque Army Air Field's wartime contributions. Kirtland AAB was put on a temporary inactive basis on 31 December 1945. When World War II ended, it
19177-407: The technique of bomb sighting. Bombardiers were required to crawl down shafts that gave way to the "bubble," from which they had bird's-eye views of the ground below. The bombardier's job was to feed the bombsight the needed information, air speed, wind speed, wind direction, altitude, and the angle of drift. As the aircraft approached the target, the pilot turned the aircraft over to the bombardier and
19328-511: The ten southernmost counties, and Northern California , comprising the 48 northernmost counties. It is bordered by Oregon to the north, Nevada to the east and northeast, Arizona to the southeast, the Pacific Ocean to the west and shares an international border with the Mexican state of Baja California to the south (with which it makes up part of The Californias region of North America , alongside Baja California Sur ). In
19479-407: The time of California's admission into the Union, travel between California and the rest of the continental United States had been a time-consuming and dangerous feat. Nineteen years later, and seven years after it was greenlighted by President Lincoln, the first transcontinental railroad was completed in 1869. California was then reachable from the eastern States in a week's time. Much of the state
19630-570: The transition from Spanish colonial rule to independent Mexican rule. In 1821, the Mexican War of Independence gave the Mexican Empire (which included California) independence from Spain. For the next 25 years, Alta California remained a remote, sparsely populated, northwestern administrative district of the newly independent country of Mexico, which shortly after independence became a republic. The missions , which controlled most of
19781-515: The two-letter code of the radio beacons that were the closest to the actual airport, such as YQX in Gander or YXS in Prince George . Four of the ten provincial capital airports in Canada have ended up with codes beginning with YY, including: Canada's largest airport is YYZ for Toronto Pearson (as YTZ was already allocated to Billy Bishop Toronto City Airport , the airport was given
19932-744: The use of special weapons and radioactive materials". Between late 1946 and early 1947, after the Atomic Energy Act creating the Atomic Energy Commission was passed, the AFSWP was established with Sandia Base as an installation under its control. A special engineering battalion was also created to aid in the assembly and maintenance of atomic bombs at Sandia Base. In July and August 1946, Kirtland Field and Sandia Base personnel took part in Operation Crossroads at
20083-529: The use of two letters allowed only a few hundred combinations; a three-letter system of airport codes was implemented. This system allowed for 17,576 permutations, assuming all letters can be used in conjunction with each other. Since the U.S. Navy reserved "N" codes, and to prevent confusion with Federal Communications Commission broadcast call signs , which begin with "W" or "K", the airports of certain U.S. cities whose name begins with one of these letters had to adopt "irregular" airport codes: This practice
20234-615: The wings under the Western Flying Training Command, the 38th held jurisdiction not only over Kirtland Field but also the Hobbs, Roswell, and Carlsbad Army Air Fields; Williams Field, Arizona; and Victorville Air Field, California. The wing relocated to Williams Field, Arizona, in February 1945 due to Kirtland Field's conversion to a Superfortress base under the Second Air Force. Kirtland Field served as
20385-649: Was "to provide flight services for the Manhattan [Engineering] District at Sandia and Los Alamos in atomic bomb testing". In early 1947, the AMC established Kirtland Field's mission as the USAAF nuclear weapons facility, a continuation of the wartime Wendover Army Air Base ( 509th Composite Group )– Manhattan Project operations. Kirtland's role in the testing and evaluation of atomic weapons increased in 1947 when Kirtland Army Air Field, became Kirtland Air Force Base . IATA airport code The assignment of these codes
20536-544: Was abandoned by 1841. During the War of Mexican Independence , Alta California was largely unaffected and uninvolved in the revolution, though many Californios supported independence from Spain , which many believed had neglected California and limited its development. Spain's trade monopoly on California had limited local trade prospects. Following Mexican independence, California ports were freely able to trade with foreign merchants. Governor Pablo Vicente de Solá presided over
20687-534: Was activated as a unit of the 58th Bombardment Wing and the host of Kirtland Field on 1 February 1946. At that time, there were fewer than 300 officers and enlisted men at the field. Because there were so few personnel on hand, morale was low and workloads were strenuous for the installation throughout the early Cold War period. On 21 March 1946, Strategic Air Command (SAC) was activated and on 31 March 1946, SAC's Fifteenth Air Force assumed operation of Kirtland Field. The 58th Bombardment Wing remained in command of
20838-576: Was eliminated as a necessary qualification for candidates. On 30 June, the War Department opened the program to any man between 18 and 36 who could meet the physical and mental requirements, including civilians as well as officers and enlisted men. At Kirtland Field, the Glider Replacement Center operated until February 1943. In May 1943, a Women's Army Auxiliary Corps (WAAC) contingent was established at Kirtland Field with
20989-552: Was extremely well suited to fruit cultivation and agriculture in general. Vast expanses of wheat, other cereal crops, vegetable crops, cotton, and nut and fruit trees were grown (including oranges in Southern California), and the foundation was laid for the state's prodigious agricultural production in the Central Valley and elsewhere. In the nineteenth century, a large number of migrants from China traveled to
21140-607: Was highly unstable, and in a reflection of this, from 1831 onwards, California also experienced a series of armed disputes, both internal and with the central Mexican government. During this tumultuous political period Juan Bautista Alvarado was able to secure the governorship during 1836–1842. The military action which first brought Alvarado to power had momentarily declared California to be an independent state, and had been aided by Anglo-American residents of California, including Isaac Graham . In 1840, one hundred of those residents who did not have passports were arrested, leading to
21291-615: Was not clear whether Kirtland Field would be closed or become a permanent USAF facility. The transformation of the Air Depot Training Station into Sandia Base, home to Sandia Laboratory and the AFSWP, kept the facility open and ultimately determined its fate. Kirtland Field was renamed Kirtland AFB, and it became the USAF's main facility for integrating new weapons designs produced by Sandia Laboratory with operational USAF aircraft and equipment. On 1 February 1946, Kirtland
21442-689: Was not the only focus at Kirtland Field between 1942 and 1945. In 1943, the USAAF Flying Training Command merged with the Technical Training Command in an effort to save manpower. The new command, the Air Training Command , became responsible for all training from classification center through pilot and technical schools. In 1943, Kirtland Field facilities expanded to support existing bombardier training plus other training missions. This expansion
21593-714: Was not usually the purpose of these small-scale battles. Men and women generally had different roles in society. Women were often responsible for weaving, harvesting, processing, and preparing food, while men for hunting and other forms of physical labor. Most societies also had roles for people whom the Spanish referred to as joyas , who they saw as "men who dressed as women". Joyas were responsible for death , burial , and mourning rituals , and they performed women's social roles. Indigenous societies had terms such as two-spirit to refer to them. The Chumash referred to them as 'aqi. The early Spanish settlers detested and sought to eliminate them. The first Europeans to explore
21744-666: Was one of the most culturally and linguistically diverse areas in pre-Columbian North America . European exploration in the 16th and 17th centuries led to the colonization by the Spanish Empire . The area became a part of Mexico in 1821, following its successful war for independence , but was ceded to the United States in 1848 after the Mexican–American War . The California gold rush started in 1848 and led to social and demographic changes, including depopulation of Indigenous tribes. The western portion of Alta California
21895-680: Was redesignated the Army Air Forces Ferrying Command in March 1942, a month after the AAC transferred the school from TWA training back to the military. The command was then redesignated the Air Transport Command in July 1942—the same month that the school was transferred from Albuquerque to Smyrna Army Airfield , Tennessee. With the departure of the 19th Bombardment Group from Albuquerque Army Air Base in
22046-502: Was short-lived; the same year marked the outbreak of the Mexican–American War (1846–1848). Commodore John D. Sloat of the United States Navy sailed into Monterey Bay in 1846 and began the U.S. military invasion of California , with Northern California capitulating in less than a month to the United States forces. In Southern California, Californios continued to resist American forces. Notable military engagements of
22197-402: Was the result of the merging of the two training commands. Expanded training at Kirtland Field included a ground school for glider pilots—called the Glider Replacement Center, which was established in July 1942. The center served as a temporary training area for glider pilots awaiting vacancies at glider schools. The Army Air Forces glider-training program had expanded, and prior flight training
22348-399: Was then organized and admitted as the 31st state in 1850 , as a free state , following the Compromise of 1850 . The Greater Los Angeles and San Francisco Bay areas are the nation's second- and fifth-most populous urban regions , with 19 million and 10 million residents respectively. Los Angeles is the state's most populous city and the nation's second-most ; California's capital
22499-454: Was to manage the engineering design, production, assembly, and field-testing of the non-nuclear components associated with nuclear bombs. Construction began on guard, storage, administrative, and laboratory facilities for the Z Division. Because the airfield was still receiving surplus warplanes, the U.S. Army constructed a fenced area for classified activities. They employed security measures including tanks, guard towers, and watch dogs to protect
22650-576: Was transferred to the Fourth Air Force for use as a flight test center. Kirtland Field was returning to B-29 Superfortress activity as the flight-testing headquarters for the 58th Bombardment Wing , which had been stationed at Roswell Army Airfield , New Mexico under the Fourth Air Force. This B-29 unit would assist the Z Division at Sandia Base with flight-testing new atomic weapons designs. The 428th AAF Base Unit (Flight Test)
22801-598: Was used by the Reconstruction Finance Corporation —later called the War Assets Administration . Old or surplus aircraft were to be sold or demolished at the site. Albuquerque Army Air Field received some 2,250 old or surplus aircraft, such as obsolete B-24 Liberator and B-17 Flying Fortress bombers, and smaller aircraft like AT-6 Texan trainers, Curtiss P-40 Warhawk and Bell P-39 Airacobra fighters.
