Very impressive, Paradoxic. But I didn't see any speed dependance anywhere in there. We are agreed, of course, that there is some amount of friction in the landing gears. I think we're also agreed that a plane on a normal runway can overcome that friction, start moving, accelerate forward, and eventually take off. I assert that the friction in the treadmill case will be no greater than the friction in the runway case, and that the plane will therefore still accelerate forward and eventually take off. You assert, however, that the friction will increase with increasing relative speed. You still haven't given any support to that assertation, however.
