A conundrum to mull over.
came across this on another site. I've not seen it here although no doubt it has been discussed elsewhere by members here. An intersting conundrum.

A plane is standing on a runway that can move (some sort of giant conveyer belt).

The plane moves in one direction, while the conveyer moves in the opposite direction. This conveyer has a control system that tracks the plane's speed and tunes the speed of the conveyer to be exactly the same as that of the plane, but in the opposite direction.

Can the plane take off?
