This debate seems to be making it's way on every message board so I thought I'd try it here. A plane (747 passenger jet) is sitting on a runway that can move (some sort of conveyor belt/treadmill). The plane moves in one direction, while the treadmill moves in the opposite direction. This treadmill has a control system that tracks the planes speed and tunes the speed of the treadmill to be exactly the same (but in the opposite direction). The question is: Will the plane (747 passenger jet) take off or not? Gassy is editing in a poll for me, thanks Gassy!
