Yes, I'm afraid it does matter because they're attached to the plane and represent the means by which the plane moves forward, whether it's being towed by a tractor or propelled by its engines.

I spent 20 years in the airline industry and have a very thorough knowledge of aircraft and the theory of flight. I assure you that I DO know that aircraft wheels are not powered, and spin freely except for being slowed by brakes.

I walk up behind you and push you forward. Do you move? Lets say I pass you a tow rope and walk along side the moving walkway and pull you against the traving sidewalk direction. Do you move in the direction I pull or do you stay still?
I stay still, IF the treadmill matches my speed, which it does in this scenario.

Believe it or not, you're the one who doesn't get it. :rolleyes:
