no no no....prop plane does not force air over the wings...the prop pulls and a jet pushes but neither have anything to do with the wings. The wings provide lift as a plane reaches a certain forward speed.

BUT as i said before, quit thinking about how a plane flies and figure out why a plane can move forward on a conveyor just like any other runway, no matter what the speed of the conveyor is.
