My degree is in aeronautical engineering. Fluid dynamics is my shizz.
This is a very easy thought experiment.
The treadmill has a negligible effect on the plane. The wheels on an aircraft are free spinning, they do not translate any thrust whatsoever to the aircraft. Ignoramus you are quite wrong about the "effect of liftoff" being made from air pressure under the wings only. Lift comes from the iterative accumulation of the pressure differentiation over the chord length of the airfoil's wingspan. Basically the plane gets sucked up into the air from above, not pushed up from beneath.
All of this is moot, though. The plane's wheels have effectively zero effect on the plane's ability to create thrust and move forward on the runway. If the treadmill is always set to match the forward velocity of the aircraft, then the 747's wheels will always be rotating at 2x the indicated airspeed. The plane will take off just fine.

"There remain four irreducible objections to religious faith: that it wholly misrepresents the origins of man and the cosmos, that because of this original error it manages to combine the maximum servility with the maximum of solipsism, that it is both the result and the cause of dangerous sexual repression, and that it is ultimately grounded on wish-thinking." ~Christopher Hitchens, god is not Great
