Since the determinig factor for lift-off is the speed of the plane versus that of the surrounding air, the plane cannot take off, as it is standing still with respect to said air. Question solved.
But unless the conveyor belt can produce an equal but opposite force to the plane ,it won't be standing still with respect to the surrounding air.
The only interface between the belt and the airframe are the wheels, which aren't powered and are free to rotate at any speed they like (well, upto breaking point), so I fail to see how such an opposing force can be exerted.
Anyway, time for BootWB to break out the algebra, and I'll put some popcorn on.
