nm, you answered it here. You do understand that the conveyor has no effect on how much air the plane can pull and or push right?
Yes I understand this. The point I was making is that a jet engine pushes all the air out the back of the plane. None of the air is pushed over the wings. Therefore, a jet wouldn't be able to lift off on a progressive conveyor belt.

A prop plane, since it forces wind from the front of the plane backwards over the wings, would. Even if it were stationary the windspeed generated by the propeller would lift it off the ground.
