History
The DH.29 Doncaster was ordered by the British Air Ministry as an experimental long-range monoplane. The aircraft was a high-wing cantilever monoplane with unswept wing of wooden structure with a fabric covering. It had a box section wooden fuselage with a single fin. The crew of two were in an open cockpit ahead of the wing. Two aircraft were built between 1920 and 1921 at Stag Lane Aerodrome. Early test with the first aircraft (Serial J6849) resulted in a redesign of the engine installation. The second aircraft (Registered G-EAYO) was built as a 10-seat commercial aircraft. The airlines were not interested in an untried monoplane and further development was abandoned and effort was put into the de Havilland DH.34 with a biplane configuration.
