Right, but the force of that drag is no where close to the force of the thrust. The plane is on wheels which are designed to roll with minimal friction.

Now, I'm assuming that the treadmill with be matching the forward thrust of the plane or the experiment is debating a moot point as we all know how a plane works.

That's the assumption of the scenario.. now if you could spin the treadmill fast enough that the friction of the wheels generated enough drag to counteract the thrust perfectly, then yes the plane would stand still and nothing would happen. Though more likely the plane would flip over if that much drag was generated at the landing gear.
