I think the whole argument hinges on the wording of the original question and not with any real possible physics.
in the original statement of the question does it say that the conveyer matches the airspeed of the plane or the wheelspeed of the plane?
airspeed and groundspeed off of the conveyer would work just fine
but matching the wheelspeed of the plane would cause a loop that is just plain impossible
