I am a bear of little brain so please only use short words when trying to explain to me how stupid I am; surely if every time the prop bites at more air to move the aeroplane forwards along our moving runway the runway moves backwards then the aircraft never moves in space, therefore has no airspeed, therefore sits on the conveyor belt revving itself to death.
I know some of you will find it difficult to believe that someone this stupid has access to a computer but it makes my head hurt so please explain.
