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].
