> i think im understanding the oringinal question wrong. according to the way i understood it my theory is correct (?). for some reason i thought that the tradmill would equal the speed of the plane in an opposite direction so the the plane would be stationary and was expected to lift off the treadmill somehow. i was unaware of the face the the plane was ‘allowed’ to still move forward on the tradmill. or am i still wrong?

I think you’ve got it. The whole point of the riddle is that the jet engines are what moves the plane, not the wheels, so the plane still moves regardless of what the ground is doing.
