Go sleep well tonight, yes, it is a fact that a treadmill does impart some tiny amount of friction, in 99.9999999999999999% of all cases, it doesn't matter. Planes have engines powerful enough in real life to overcome infinitesimally minute variables, but in the case of your imaginary argument, it is possible that they may not. You may as well start throwing in gravity variables, as well, the higher the gravity, the more friction you will get in the wheel bearings.

Agreed. The only part I take exception to is your poking at me because I've personally conceived of an "imaginary argument"......as if my imaginary argument is somehow interfering with your larger, concrete discussion about airplanes on runway-sized treadmills. (That goes for Grundle, as well.)
