The Aircraft Disposals Company (ADC) or Airdisco, was a British firm established in March 1920 to take advantage of the large number of World War I-surplus military aircraft on the market.
One of the founders was Frederick Handley Page, the British aviation pioneer. ADC bought the entire available stock of surplus aircraft engines and spares, including 10,000 airframes and 30,000 engines, for the sum of £1,000,000 plus a share of any profits. Many ex-military aircraft were converted to various civil roles before being sold on while others were sold to military buyers.
By 1925, it had sold 2,000 airframes and 3,000 engines, generating profits of over £2,500,000, of which half was returned to the British Treasury.
The company had several sites across Britain including 11 acres (45,000 m2) of Regents Park in London known as Marylebone Green. Three of the National Aircraft Factories became part of the Aircraft Disposal Company including Aintree in Liverpool, Waddon in Croydon, and at Stockport near Manchester.
