Bossi & Bonomi Pedaliente

Enea Bossi and Vittorio Bonomi's Pedaliente had a wingspan of 17.6 m (57¼ ft) and had two chain-driven contra-rotating propellers. Thanks to the Italian government's ruling that all man-powered aircraft contestants had to conform to conventional airworthiness standards, the Pedaliente was far too heavy, weighing nearly 100 kg (220 lb), and could manage only downhill glides even after a bungee launch.

A 1936 human-powered aircraft, designed by Enea Bossi. Built by Vittorio Bonomi, flown by cyclist Emilio Casco, 80 flights made.
