You've mentioned this five times now, and you've been right each time, but they're just not understanding what you're saying of course. The plane can take off, for all the reasons stated already, but when it does take off, the wheels will be moving x mph faster than the conveyer belt, where x=the plane's velocity relative to the ground/air/whatever.

The wheels will only move as fast as the force spinning them. In this case the conveyor belt. Remember they are independent of the movement of the plane. The plane can move and the wheels can stay still. The wheels can move and the plane can stay still. Both can move independently at the same time (as in this case).

Yes, they can, but the OP stated that they are not. It's like asking how long does it take a car to travel from point A to point B (where distance >0) moving at 0mph, and some people say it won't ever get there, but then other people say "OMG retard you can accelerate the car and then it will get there" and then the original people sit there scratching their heads wondering where the misunderstanding is.
