that right there sums it off, whoever said it isn't propelled by the wheels is an idiot, of course it isn't propelled by the wheels, it needs lift hence why the plane needs to be MOVING forward if the plane is stationary due to the treadmill matching its speed then there's no lift to make the plane take off

case solved
