I don't think you've understood the problem  |
Let's assume that (as in idi's example) the plane is being held up by an invisible force, but stationary (on bricks is a fine example).
The engines can thrust and thrust and thrust and thrust, but they aren't pushing against anything. They're just blowing hot air out.
To generate enough air underneath the wings, the plane needs to be moving through the air at a high speed. We know it isn't moving, as the treadmill is stationary (I assume) and the plane isn't moving off the treadmill. So no air flow exists (and any that does would just be generate by the engines and is insignificant).
