 Twenty-one Carvairs were produced in the UK, with production of aircraft 1, 11 and 21 at Southend Airport and the balance at Stansted Airport.The final three aircraft were delivered to Australia's Ansett-ANA, which supplied its own DC-4s to ATL for conversion, unlike the previous 18 aircraft that were purchased by ATL and either sold on or transferred to associate company British United Air Ferries (BUAF).One of the two aircraft still flying in June 2007 was an ex-Ansett airframe.
