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?

No.If the plane doesn't move you don't have lift.No lift,No flight.
(tybardy got it wrong.the lower air pressure is above the wings.if you have lower air pressure below the wings the plane will drop like a rock.)

It depends on the speed of each and also, on the length of the conveyor belt that is being used as the runway.
If the speed is insufficient to build up the momentum, the plane cannot fly. Also, if the runway length is short of the length required by the plane to lift off, it will crash.
Since both the plane and the conveyor belt are moving, if the speed is sufficient, it will take off. In fact moving in the opposite direction will facilitate build the momentum (the racing you feel just before lift-off) !!

If the conveyer belt moves at exactly the speed of the plane the plane would be virtually stationary.
If the belt moves faster than the plane, the plane would be going backwards.
Ever try to walk up or walk down the escalator?
Next time try to and look down on the moving steps.
At one point of time the belts seems not to be moving at all and appears stationary.
Wonder why?
Because your speed of walking matches the speed of the moving escalator.

Yes, of course it can take off. A plane isn't propelled by its wheels, it is moved forward by its engines or propellers which push air (not wind) backwards and impel the plane forward, picking up speed until enough lift is generated for take-off. The conveyor belt would only make its wheels spin, and would have no effect on the plane's forward movement.

Yes it will. The force that moves the plane forward comes from the engines, which push on the air. The wheels only support the plane when it is on the ground.

No...the plane's wheels have got to go faster than the conveyer belt. It would be like you running on a tread mill.

no because the wheels are going one way the the belt thingie is going the other way and plus the plane can take off with one wind

No, it is the forward speed of the plane that causes lift to be generated by airflow over the wings. If the plane does not move forward to generate lift, it dose NOT go up.

why would a plane be on a massive conveyor belt? O.o

So you are saying you are pushing a huge airplane through the air, and there is no wind? You have created no wind by moving a huge airplane through the air. This could only be possible in a vacuum.
