Stag Lane Aerodrome was a private aerodrome between 1915 and 1934.
The land for an aerodrome was purchased by the London & Provincial Aviation Company during October 1915. The company used the aerodrome for flying training during the First World War. London & Provincial ceased flying in July 1919 after a dispute with Department of Civil Aviation (see United Kingdom Civil Aviation Authority), which refused them a licence.
Stag Lane became the main base of The de Havilland Aircraft Company Limited in 1920. Former wartime aircraft were refurbished in the early years, and the company designed and built large numbers of aircraft at Stag Lane in the 1920s and early 1930s. In 1934 the company moved to a larger factory and airfield at Hatfield Aerodrome, Hatfield, Hertfordshire.
Stag Lane Aerodrome was sold for housing development in 1933, though a small 15-acre (61,000 m2) site was retained as a factory and offices for The de Havilland Engine Company Limited. The last flight from the airfield was a de Havilland Hornet Moth in July 1934.
