The 'myth' is that if you put a plane on a conveyor belt/treadmill, and it is free to move at whatever speed the plane's wheels are turning (and always matching this speed), will the plane take off or remain stationary?
Here's a hint for y'all: The wheels arent driven by driveshafts. They just spin freely (without friction for the sake of argument in this example). Yes, we already knew this. But think about it again in the context of this example.
