The de Havilland Aircraft Company (less commonly spelled de Haviland) was a British aviation manufacturer founded in 1920 when
Airco, of which Geoffrey de Havillandhad been chief designer and owner, was sold to BSA. De Havilland then set up a company under his name in September of that year at Stag Lane Aerodromein Edgware, England. The company later moved to Hatfield in Hertfordshire, England. De Havilland Aircraft Company was responsible for producing the first passenger jet and other innovative aircraft.
Initially, de Havilland concentrated on single and two-seat
biplanes, essentially continuing the DH line of aircraft built by Airco, but powered by de Havilland's own Gipsy engines. These included the Gipsy and Tiger Moths. These aircraft set many aviation records, many piloted by de Havilland himself. Amy Johnsonflew solo from Englandto Australiain a Gipsy Moth in 1930.
The Moth line of aircraft continued with the more refined (and enclosed) Hornet Moth and Moth Minor, the latter being a low-wing
monoplaneconstructed of wood. One of de Havilland's trademarks was that the name of the aircraft type was painted on using a particularly elegant Roman typeface, all in capital letters. When there was a strike at the plant, the artisans who painted the name on the planes used the same typeface to make the workers' protest signs.
The DH 84 Dragon was the first aircraft purchased by
Aer Lingus, who later operated the DH 84B Dragon Express and the DH 89 Dragon Rapide. De Havilland continued to produce high-performance aircraft including the high-speed twin-piston-engine DH 88 Comet mail plane, one of which became famous in its red livery as the winner of the MacRobertson Air Racefrom England to Australia.
The high-performance designs and wooden construction methods culminated in perhaps the most famous de Havilland aircraft — the Mosquito, constructed primarily of wood because of the shortage of aluminium during the Second World War. The company followed this with the even higher-performing Hornet, which was one of the pioneers of the use of metal-wood and metal-metal bonding techniques.
After the Second World War, de Havilland continued with leading-edge designs in both the military and civil field, but several public disasters doomed the company as an independent entity. The experimental, tailless, jet-powered
de Havilland DH 108 Swallowcrashed in the Thames Estuary, killing Geoffrey de Havilland Jr, son of the company's founder. The de Havilland Cometwas put into service in 1952 as the eagerly-anticipated first commercial jet airliner, twice as fast as previous alternatives and a source of British national pride. The Comet suffered three tragic and high-profile crashes in two years. Less well known, but equally disastrous, was the explosion of the DH 110 prototype during the 1952 Farnborough Airshow, which also killed members of the public. Hawker Siddeleybought de Havilland in 1960 but kept it as a separate company until 1963. In that year it became the de Havilland Division of Hawker Siddeley Aviation [ [http://rafmuseum.org.uk/london/exhibitions/dehavilland/post_war.cfm RAF Museum website de Havilland History page] Access date: 12 August 2007] and all types in production or development changed their designations from "DH' to "HS" (see Hawker Siddeley Trident, BAe 146and BAe 125). The famous "DH" and the de Havilland name live on, with several hundred Moths of various types and substantial numbers of many of the company's other designs still flying all over the world.

Loss of competitive advantage
Following the structural problems of the company's jets in 1954, all remaining Comets were withdrawn from service, with De Havilland launching a major effort to build a new version that would be both larger and stronger. This one, the Comet 4, enabled De Havilland to return to the skies in 1958. By then, the United States had its Boeing 707 jetliner along with the Douglas DC-8, both of which were faster and less costly to operate. Orders for the Comet dried up.
De Havilland also pushed into the new field of long-range missiles, developing the liquid-fueled Blue Streak. It did not enter military service but became the first stage of Europa, a launch vehicle for use in space flight. In flight tests, the Blue Streak performed well—but the upper stages, built in France and Germany, repeatedly failed. In 1973, the Europa program was canceled, with Blue Streak dying as well. The last of them wound up in the hands of a farmer who used its commodious fuel tanks to house his chickens.
De Havilland returned to the airline world in 1962 with a three-engine jetliner, the Trident. However, he designed it to fit the needs of one airline and one man: MRAF Sholto Douglas later Lord Sholto Douglas, chairman of British European Airways. Other airlines found it unattractive and turned to a rival tri-jet: the Boeing 727. De Havilland built only 117 Tridents, while Boeing went on to sell over 1,800 727s.

de Havilland Canada
de Havilland Canadawas formed in 1928 to build Moth aircraft for the training of Canadian airmen and continued after the war to build its own designs suited to the harsh Canadian operating environment. These are listed below. The DHC-2 through DHC-7 aircraft were all STOLdesigns. de Havilland (Canada) was eventually incorporated into the Bombardiergroup of companies and the Dash Eight remains in production with a particular emphasis being placed on its quiet operation in comparison to other aircraft of a similar size. In May 2005, Bombardier sold the rights to the out-of-production aircraft (DHC-1 through DHC-7) to Viking Air Ltd. of Sidney, British Columbia.
Aircraft produced by de Havilland (Canada) Aircraft include (chronologically):
*DHC-1 Chipmunk nicknamed "The Chippy" 1946-1982
*DHC-2 Beaver STOL utility aircraft 1948-1967
*DHC-3 Otter STOL utility aircraft 1953-1967

de Havilland Australia
The first foreign subsidiary was set up in Australia in March 1927 as de Havilland Aircraft Pty. Ltd. The company moved from Melbourne to Sydney during 1930 where it acted as an agency for the parent company, with assembly, repair and spares facilities for the company's popular sporting and airliner types. Aircraft design and full manufacture by de Havilland Australia (DHA) did not take place until the Second World War, when the company began production of the DH 82 Tiger Moth primary trainer at Bankstown, NSW.
During the Second World War, DHA designed a small troop-carrying
gliderto be used if Australia was invaded by Japan. The DH-G1 emerged in mid-1942 and utilised the DH 84 Dragon forward fuselage, which was in production at the same factory. The two built served as prototypes for the definitive DH-G2 produced the following year but the need had passed by this time and only six DH-G2s were built. The company also began to manufacture the Mosquito, with deliveries to the RAAF being first made in 1944. A total of 212 Mosquitos were built at Bankstown between 1943 and 1948. Some of these aircraft continued in RAAF service until 1953. Licenced production of the de Havilland Vampire began in 1948, with the first of 190 built flying in 1949.
Another DHA design, the
de Havilland DHA-3 Drover, was manufactured between 1948 and 1953. Only 20 were produced, mostly for the Royal Flying Doctor Service (RFDS), Trans Australia Airlinesand Qantas. The DHA-3 Drover was a 3-engined light transport derived from the DH 104 Dove, capable of carrying six-eight passengers. It was designed as a replacement for the DH 84 Dragon, which was common in Australia due to its wartime production by DHA. The engine chosen for the new design was the de Havilland Gipsy Major Mk-10 4s. Several Drovers were later re-engined with more powerful Lycoming O-360horizontally-opposed engines to improve performance.
The de Havilland Australia concern is now owned by
Boeing Australiaand is known as Hawker de Havilland Aerospace.

de Havilland engines
As well as a prolific aircraft builder, de Havilland was also a significant producer of aero engines. This went against usual practice- usually engines are designed and produced by a dedicated company though in the UK
Bristol Aeroplanehad a substantial engine business and Armstrong Whitworth Aircraftwas part of the same business as Armstrong-Siddeley[After 1935, both part of the Hawker group.] The successful "Gipsy" and the later developments such as the Gipsy Major were successful and popular power units, being used in nearly all of de Havilland's light designs and several aircraft from other manufacturers. Gipsy engines were relatively unusual by the 1930s/40s because they were in-lineengines, at a time when radial or opposed-action engine layouts were more popular. The de Havilland company was also a competitor to Rolls-Royce and Metrovickin the early years of the jet enginedevelopment. Employing the services of Frank Halfordthen buying out his company they produced the de Havilland Goblinand de Havilland Ghostengines for first their jet fighters then the Comet.
