Okay, I see that.

So basically the question is can a Plane take off without moving forward relative to the ground? Regardless of whether or not it is moving relative to the treadmill, its not moving relative to the ground, so of course it cant.

But the original question just asked about the speed of the wheels relative to the treadmill, not the plane.
