Disagree. I am not saying that the plane is floating. what do wheels do for a plane. they remove the "situation of friction" that would be present if there were no wheels. what does a plane need to move as fast a possible across the ground. other than its engines it needs as little ffriction with the ground as possible. be it wheels skis grease what ever. the wheels are simply there to provide no resistance to the ground for forward movement. So if there is minimal resistance how can a treadmill no matter how fast it is spinning all of the sudden tranfer that resistance through wheels that are resistanceless. You said that a plane moves it self forward from the thrust relationship between the engine and the air. i did not see ground in that relationship equation so how can the moving ground aka the treadmill insert its self into that equation. Try this. get an aeronautical physics degree . then youll understand. this question was my senior research. do you think that if i was wrong that i would have recieved my degree. How many people have changed their mind from take off to not take off. none. everyone that changes their mind changes to take off.
