IMAGINE A 747 IS SITTING ON A CONVEYOR BELT, AS WIDE AND LONG AS A RUNWAY. THE CONVEYOR BELT IS DESIGNED TO EXACTLY MATCH THE SPEED OF THE WHEELS, MOVING IN THE OPPOSITE DIRECTION. CAN THE PLANE TAKE OFF? NO; YES. THE ENGINES ARE PROVIDING THE THRUST TO PROPEL THE AIRPLANE FORWARD, NOT THE WHEELS... NO
