   How long did a Cornu helicopter stay in the air?

   • The Cornu helicopter is reported to have made a number of short hops, rising perhaps 1.5 or 2 metres (5–7 feet) into the air and staying aloft for something less than one minute. This was long enough for Cornu to learn that the control systems he had designed were ineffective, and he abandoned the machine soon thereafter.
