De Havilland DH.50
The de Havilland DH.50 was a 1920s British large single-engined biplane transport built by de Havilland at Stag Lane Aerodrome, Edgware, and licence-built in Australia, Belgium, and Czechoslovakia. History In the early 1920s, Geoffrey de Havilland realised that war surplus aircraft would need replacing, so his company designed a four-passenger-cabin biplane, the ''DH.50'', using experience gained with the earlier de Havilland DH.9. The first DH.50 (registered G-EBFN) flew in August 1923 and was used within a few days by Alan Cobham to win a prize for reliability during trial flights between Copenhagen and Gothenburg. Only 17 aircraft were built by de Havilland; the rest were produced under licence. The different aircraft had a wide variety of engine fits. In 1924, Cobham won the King's Cup Race air race in G-EBFN averaging 106 mph (171 km/h). Cobham made several long-range flights with the prototype until he replaced it with the second aircraft.
