Beskriuwing
Français : En 1907, l'inventeur français Paul Cornu a fabriqué un hélicoptère qui utilisait deux rotors contrarotatifs de 20 pieds (6 mètres) entraînés par un moteur Antoinette de 24 ch (18 kW). Il a soulevé son inventeur à environ cinq pieds (1,5 mètre) et est resté en l'air une minute.
