Plane 3

It sounds like a great idea – you could let the aircraft get up some real speed, stop the treadmill and let the plane fly into the air. Except it doesn’t work.

To get airborne, the only thing that matters is airspeed. If the air is not flowing quickly enough over the wings, there is nothing to lift it into the sky so you need a lot of runway to build up speed.
