No matter what speed the wheels are going...the plane will be PULLED/PUSHED forward by it's propulsion system whatever it may be...the wheels will just be spinning faster when it takes off....
Riddle me this, if the treadmill STOPS all of a sudden, will the plane also stop all of a sudden? Like a bike on a treadmill or a person running on a treadmill?!
EDIT: So if the treadmill does stop all of a sudden will the plan SUDDENLY be airborne as well?!
Also, the Y2k jet bike, they can't dyno that bike, if they put that on a treadmill that matches the speed of the wheels, that bike will STILL move forward, it'll never "take off" but the bike wheels won't care, the bike is being propelled forward!
