I dont know what all the fuss is about. The plane will not takeoff for
the reason that the all the plane is doing is keeping stationary. In
actual fact the trust thats produced is not producing thrust, its only
compensating from the drag thats pull the aircraft back. (treadmill) in
order to take off the plane must superexceed the opposing force and
establish that trust actually does exceed drag. hence the the plane
must build up momentum (in the correct direction)

correct ?
