[Joslin Hall Books & Ephemera]

1930s Pterodactyl IV J.W. Dunne Airplane Promotional Photo.

A photo of J.W. Dunne’s Pterodactyl IV, “Like a huge nocturnal bat in  
flight is this novel plane, recently acquired by England’s Royal Air  
Force. Photo was made as the aircraft scored over Farnborough Air  
Station”.

“Captain G.T.R. Hill developed the Pterodactyl series in an attempt to  
develop a safer aircraft: many pilots lost their lives when their  
aircraft stalled, went into a spin and flew into the ground, and Hill  
wanted to develop a design which was resistant to stalling and  
spinning. The pioneer J. W. Dunne had previously developed stable  
aircraft in the form of tailless swept wings and Hill took Dunne's  
ideas as his starting point. Helped by his wife, he constructed a  
prototype which was flown as a glider in 1924. The design gained  
official interest and in 1925 it was fitted with a 35 h.p. Bristol  
Cherub engine and taken to Farnborough. It was later demonstrated to  
the Secretary of State for Air, Sir Samuel Hoare. All subsequent  
examples were funded under Air Ministry contract and built by Westland  
Aircraft, who took on Hill for this purpose. - Pterodactyl IV [was a]  
three-seat cabin monoplane of 44 ft 4 in span and 19 ft 6 in length,  
produced in 1931. The aircraft was given serial K1947 and first flew  
in March 1931 with a 120hp de Havilland Gipsy III engine in a pusher  
configuration” [Wikipedia].
