The Westland-Hill Pterodactyl Mk V - an experimental tailless aircraft from 1935. The engine is a Rolls-Royce steam-cooled Goshawk. (h/t Arnold Ives)
British 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. Hill’s designs were inspired by the pioneer J. W. Dunne, who had previously developed stable aircraft in the form of tailless swept wings.
