airplane vs conveyor belt

Saw this on another forum. Might be old.

Imagine a plane is sat on the beginning of a massive conveyor belt/travelator type arrangement, as wide and as long as a runway, and intends to take off. The conveyer belt is designed to exactly match the speed of the wheels at any given time, moving in the opposite direction of rotation.
There is no wind.
Can the plane take off?

Explain why it can, or cannot, take off?

No it cant take off because it uses the wind passing over and under the wings to create an upwards force to take off. If it was on the conveyor belt, it would be effectivly standing still and therefore have no wind going over the wings and therefore would not be able to create the upwards force. I dont think that makes much sense cause Im really tired but hopefully someone will understand.

you sound like a jerk!
