Bossi-Bonomi Pedaliante

The aircraft successfully traveled 1 km (0.62 mi) as part of an Italian competition, but was denied the monetary prize due to its catapult launch.

A spring scale was attached to the tow line to sense the force exerted by the bicyclist, the results confirming that a speed at which the necessary lift could be obtained was indeed attainable.

Due to the newly-formed Rome-Berlin axis, similar political and military events were staged during the initial period in both Italy and Germany to help strengthen that bond.

The pilot sat semi-upright, and a bicycle chain transmitted the power from the pedals to an overhead transverse shaft that was bevel-geared to the two propellers, which extended from the wing on each side of the fuselage.

This set a world record for human-powered flight, but as a catapult launch was not permitted in the rules of the competition, the Pedaliante did not win the prize for which it was designed.
