At this point, the belt -- which is a perfect conveyor belt -- instantly
speeds up to infinite speed. The airplane's wheels -- which are perfect
wheels -- likewise instantly spin up to infinite speed. Since the wheels
are perfect and have no friction, the airplane is not affected and takes
off anyway.

In order for the friction to really be 0, the plane must be in a vaccuum.

However, in a vaccuum, there would be no air to travel past the wings to
generate lift, and therefore it would not fly.
