OK...let's end this once and for all.
The question stated that the treadmill has a speed tracking system on it that tracks the plane's speed, and adjusts its speed to match the plane's speed but in the opposite direction. Basically what this system does is adjusts the treadmill speed so that all forward movement of the plane is cancelled out. No forward movement of the plane = no airflow over the wings = no lift generated = plane will not take off.
Now if the plane's liftoff speed was say...100 knots...and the treadmill was fixed at that speed...the plane will take off...but would have to generate twice the thrust it would have to generate if it were on a non moving runway, and the wheels would be spinning twice as fast.
OK...let's end this once and for all.That's a good one.

Wheel driven? Where did you get that from?
It doesn't track the speed of the wheels...it tracks the speed of the aircraft itself. The speed of the wheels is irrelevant.
Didn't state whether it was facing into the wind or not.......

YES, YES, YES
Wheel driven? Where did you get that from?Since you think the treadmill cancels out the speed of the aircraft, one can only assume that you think the airplane is driven by its wheels.
OMG...are we really doing this again?!?!?!?!?

By "speed of the aircraft" I am referring to the forward movement of the aircraft's fuselage...not the speed of the wheels.
