So if an aircraft is on a treadmill it is really not moving forward anymore than the treadmill is moving in reverse in wich case would not create the sufficient amount of force to lift the aircraft. The wheels will be spinning but the aircraft is in all reality sitting in one position.
Just my opinion.
Huh? Imagine that the treadmill is as long as a normal runway. It will travel down the treadmill while picking up speed.
