The airfield was set up in 1928 when the de Havilland family bought of grassland to house the de Havilland Flying School. In 1938 the airfield was taken over by the government, and during the Second World War was the home of the Air Transport Auxiliary between its formation in early 1940 and disbandment on 30 November 1945. The ATA staged a unique Air Display and Air Pageant at White Waltham on 29 September 1945 which was opened by Lord Beaverbrook and featured a memorable static park of Allied and German aircraft and the flying included Alex Henshaw displaying a Seafire Mk45.
