i think its the problem as stated that sucks and is unclear....but anyway
what RJ and Ginger is saying is:
the treadmill is as long as a runway. the thrust of the engines push against the air (not the treadmill) to propel the plane forward, so the treadmill really doesnt even move, or if its already moving, it means the wheels are just spinning faster.
remember, a treadmill is turned by the backward (push-off) pressure of your feet or wheels. a plane does not exert this pressure, it uses the air to push off.
