If you made something in the real world that tried to constantly match the speed of the belt to the wheels, the belt would quickly keep going faster until something blew up (a la AMJ). The plane would continue on, blissfully unawares.
LOL, damn those smilies...

That wouldn't be impossible. If someone had pockets deep enough that could be built. But they done this on tread mills with remote control planes so its not to hard to believe.
And a float plane can take off on water. I think the floats would cause more drag then the wheels/wheel bearings being over worked and it has no problem taking off.
If you stand on a tread mill with roller skates on you are like a plane before the engines are turned off. Don't try to skate, just stand there because the plane doesn't get forward movement from its wheels. They are just like casters on your office chair. The wheels allow the object they are attached to to move freely across the ground when they pushed.
You push your office chair with your feet to move it. The plane uses and engine that will pull/push it self through the air, Once it is moving fast enough through the are for the wings to work it takes off. The speed of the ground under the wheels has no affect.
The ground is a moving platform on a aircraft carrier.
