I KNOW I KNOW, it has been munched over a thousand times, but I would like to hear your opinion on this.
For all who don't know what I'm talking about, here's the original question:
"A plane is standing on a runway that can move (some sort of band conveyer). The plane moves in one direction, while the conveyer moves in the opposite direction. This conveyer has a control system that tracks the plane speed and tunes the speed of the conveyer to be exactly the same (but in the opposite direction). Can the plane take off?"
