The plane will move forward and will take off when it reaches the required air speed.
Why would you assume the friction between the wheels and the plane is zero?

There would be no air speed. The treadmill stops the plane from moving forward.

You have to read the initial question again. This isn't a regular treadmill, that the plane can eventually accelerate against and take off. It is being held stationary by the magical super forces of exact speed.
