Enea Bossi, an Italian aircraft designer, started his research into HPF in the 1930s by fitting a propeller onto a tricycle. This proved to be an unstable vehicle and he erroneously believed that an HPF with only one propeller would also be unstable, hence his choice of wing-mounted contra-rotating propellers with the accompanying complicated drive. The Pedaliante was of conventional glider configuration and construction, and with a span of 58 ft (17.7 m), area of 250 square feet (23.2 m2) and weight of 220 lbs (100 Kg). It is generally agreed that this aircraft made many dozen flights after towed launches. There has been much dispute as to whether it ever took off under the pedal-power of the pilot alone. There is no record of official observation of it having done so. If it did, it would of course have been a world-first, preceding SUMPAC by thirty-five years. Some of the arguments for and against the validity of Bossi's claim to have done so are presented by Sherwin (1976). In the period from 1958 to November 1961, one knew that the Pedaliante "might have done", and this mirrored most people's expectations about whether their own projects would ever work, or indeed whether HPF would ever be possible. Yes it's true, we really did say "Yes, but will it fly ? ". Neither of these pre-war aircraft had ailerons, yet all the early British HPA used such devices to attempt to get lateral control.
