but… if the plane is on ground that isnt moving… the speed of the wheels IS the speed of the forward motion at the time of liftoff (which i think was measured at 25 mph)
With the tarp moving in the opposite direction at 25mph the wheels would be moving at ~50mph at take off
they also did measure the required take off distance at ~85 feet
and the trucks velocity in the opposite direction ~approx 25mph to start and then flooring it when the plane started to move.
so im not quite sure what your trying to say
