The problem is, that the aeroplane does move forward, it must, there is
nothing to stop it from doing so.

Imagine (or try)...

1. Hold a wheel between your fingers so it can spin.
2. Put wheel on a treadmill which is not moving.
3. Provide thrust (forward motion) to the wheel from your arm.
4. Observe wheel moves forward.
5. Turn on treadmill, and place wheel on the moving treadmill.
6. Apply SAME amount thrust as you did in 3.
7. Observe same forward movement (discounting the very small friction)
is produced, although the wheel spins much faster.

The thrust acts independantly of the treadmill, you need a treadmill at
least as long as a short field takeoff
