Only if it's 'taking off' a celebrity or politician. (impersonation...groan...)Imagine a 747 is sitting on a conveyor belt, as wide and long as a runway. The conveyor belt is designed to exactly match the speed of the wheels, moving in the opposite direction.
Can the aeroplane take off?
It's an old one but a goodie, once you know the correct answer it's a bit boring, but there are loads of variations on this question which have different answers...
