Gods no! The whole point is that the plane *doesn't* remain stationary, it moves across the surface of the treadmill just as it would the ground, as the force created by its jets doesn't not care how fast the wheels on the bottom of the plane are spinning - it's pushing the plane forward.
Like has been said before. Turn on your treadmill at home. Get a toy car. Push it along the treadmill. Was it impossible? Even if the treadmill was going "really" fast? No, your hand it not affected by the treadmill, only the wheels of the car are, but they are not providing the mechanism for movement.
