A plane is standing on a runway that can move (like a giant conveyor belt). This conveyor has a control system that tracks the plane's speed and tunes the speed of the conveyor to be exactly the same (but in the opposite direction).
Not wheel speed.
There is no reason why the plane won't fly.
Think of this, if the plane is just sitting there, someone straps a rope to the plane. From off the belt they pull on it for 10 feet.
Now the plane will move 10 feet. The belt would have moved backwards 10 feet, and the wheels turned a total of 20 feet.
