It's simple.. if you can accept that -10 and + 10 = Zero than you'd have to accept that the thusters were set so that the plane is at +10 910MPH forward) and the threadmill is moving at -10 (10 MPH Backwards), so the plane is stationary, (AT ZERO), wheels spinning and all, UNTIL you fire the engine at 100%. This is logical. Cause if the treadmill is at -10 and the plane's engines are off, then the plane will move backwards on the treadmill at -10 (10mph backwards), just like if you were to just stand still on a moving treadmill. Even with rollerblades. Correct so far?)
No - u are missing the fact that the wheels are "free-rolling". In this example, there would be no "backwards" motion at all. But even if there was, this would be a negligent amount.
