It doesn't matter how fast are the wheels rotating. Plane will not launch because it needs to be pushed by air, which will not happen beause plane is not moving against the air.

So since we are working in an ideal world where plane sized runways exist, if the wheels have mass and are frictionless and operate in a vacuum and there are no relativistic effects, the treadmill feedback loop described by interpretation #3 could continuously accelerate the wheels and hold back the airplane.

A plane preparing to take off in a westerly direction on an east/west runway is already on a treadmill going 1,000 miles an hour against the intended take off direction. Does anyone think an airplane of any type cannot take off to the west? Forget the treadmill.

The plane engines push on the air, they do not power the wheels. The plane will move forward and take off regardless of what the wheels or the tredmill does. Myth Busters solved this one already.

This brings to the forefront the question of "what is the treadmill actually doing?"
