The Cornu was the first aircraft capable of free vertical flight. Designed and built by bicycle-maker (another one!!) Paul Cornu, this tandem contra-rotating rotors “Flying Bicycle” achieved -barely- that historical feat in 1907.
The glory was brief. After some more hops and trials Cornu came to the conclusion that his designs suffered serious control problems and that linked with his lack of funds ended his contribution to aviation.
