Would Aeroplanes or Helicopters work on our Moon?
In general , I think , in Aeroplane Case:
(1) Air is required for Aeroplanes to float : Would Moon have enough air?
(2) High speed is required for take-off : Would this high take-off speed actually be more than the escape velocity?
In Helicopter Case:
(1) The fans rotate at high speed which raise the vehicle because of air. Does Moon have enough air?
(2) The rear fans enable Control to maintain Direction. Will Moon have enough air to allow this Control?
I will not include hover-crafts here!
