The Return of the most infamous HB thread of all time... :D

[gn7]

A plane forward motion is independent of the surface is sitting on. Its not a car on rollers. It doesn't need the surface to remain still for it move forward. A plane pulls itself thru the AIR, not push itself along with the wheels on a stationary surface. It moves forward RELATIVE TO THE AIR not the tread mill.

Like snoc said, but confused it with a bunch friction bullshit. You just need a tread mill long enough. But the plane IS going to screw itself forward THRU THE AIR regardless if its on a treadmill.
Lets keep our eyes on the ball here, The plane does need the ground to move forward on, whether its flying or not, its irrelevant.
