1. How does an airplane take off on a normal runway?

An airplane uses jets or props to push against the air with enough force to accelerate. As the wings slice through the still air, relative airflow creates lift and the plane takes off.

2. Could a conveyor turning backwards under the wheels hold it back?

No ... since the airplane's landing gear rolls freely, the conveyor has nothing to push against and cannot cancel out the plane's forward motion. It would spin the wheels faster than usual but the plane would take off normally.

I see your point now. I agree!
