The de Havilland DH.29 Doncaster was a British long-range high-wing monoplane of the 1920s built by de Havilland.
History
The DH.29 Doncaster was ordered by the British
engine installation. The second aircraft (Registered G-EAYO) was built as a ten-seat commercial aircraft. The airlines were not interested and further development was abandoned, effort being put into the biplane de Havilland DH.34. A proposed military reconnaissance version, the DH.30, was never built. The two aircraft finished their life at RAF Martlesham Heath
with tests and trials, particularly on the thick-section cantilever wings. The Doncaster was the first British aircraft to use such wings.
