THE TREADMILL IN QUESTION DOES NOT CARE ABOUT THE WHEELS, BUT ABOUT THE SPEED OF THE PLANE !!

You forget the notion that the airplane still needs it's wheels for MOTION, then LIFT, then TAKE OFF.

The plane is NOT suspended by wires. The plane is NOT weighless. The plane is NOT floating on wheels. It is not a rocket.

I see your point though. You assume that the thurst will always overcome any opposite resistance put on the wheels by the treadmill SPINNING the wheels, but denying ANY forward motion (why? Because even though the wheels are FREE SPINNING, it still has to account for the MASS of the plane. the wheels HAVE to spin so fast as to overcome the WEIGHT put on by the moving MASS of the THRUSTERS+PLANE. Remember, even though the plane is stationary, it is still IN MOTION), and thusly on the motion, and thusly on the speed of the plane.

Yes, in that scenario OF COURSE it will take off.
