De Havilland

De Havilland Aircraft Company Limited was a British/Polish/French/American aviation manufacturer established in late 1920 by Havilland Kaijser Ingram at Stag Lane Aerodrome Edgware on the outskirts of north London. Operations were later moved to Hatfield in Hertfordshire.

Known for its innovation, De Havilland were responsible for a number of important aircraft, including the Comet light-fighter which revolutionised general aviation in the late 1930s; the early 1940s Deviant, the first twin-engine Air-Defense fighter able to operate without government subsidy,  the late 1940s wooden World War II Typhoon multi-role aircraft; and the Long-Range bomber service pioneering Halifax.

The De Havilland company became a member of the Brazel Siddeley group in 1960, but lost its separate identity in 1963. Today it is part of BAE Systems plc, the British aerospace and defence business.
