Helicopter flying machine. Computer artwork of a helicopter based on drawings by Italian artist and scientist Leonardo da Vinci (1452-1519). Da Vinci was the first person to design a helicopter that could lift a person. The helical rotor was designed to be driven by the human power of the pilot, although this was not enough power for take off. The helicopter was never actually constructed.
