This was posted on another forum and it has gone about 40 pages so far. I cant believe people cant figure this out. Its scarry how dumb people are.
A plane is standing on a runway that can move (like a giant conveyor
belt). This conveyor has a control system that tracks the plane's
speed and tunes the speed of the conveyor to be exactly the same (but
in the opposite direction) instantly.
Will the plane be able to take off?
