Perhaps I'm misunderstanding what you're arguing (like everyone else apparently). Are you saying that a treadmill couldn't essentially "launch" the plane by moving in the same direction because the wheels would spin and the plane wouldn't move? That's a very different argument than the one I think everyone else is talking about - that a plane could take off under its own power while a treadmill was under it and moving in the opposite direction.
