But lift is generated by air flow over the wings. Should there be air in this thought experiment, no mater how the plane is moved, lift will be generated by the difference in air pressure above and below the wings as the plane moves.
Whether it is a F-16 being catapulted of an air-carrier or a plane being moved by a treadmill, what causes the plane to take of is the lift generated by the air flowing over and bellow the wings.
While the plane may be static relative to the treadmill, it isn't static relative to the air surrounding it, so lift will be generated. Think for example of an airplane being carried by hurricane force winds out of the ground, even if it was standing still it was still lifted up by the hydrostatic lifting force of hurricane force winds.
