The earth is a treadmill. Goes about about 900 knots (at equator).
Does that bother your takeoff? Suppore treadmill stopped (rotation
stopped). Takeoffs any different?

You forgot one major difference....in the case of the earth, the
airmass is travelling at the same 900kts, ignoring any localized
wind effect....not so in the treadmill case.

So when a treadmill runs the wind starts blowing ? OK... wot are yer
saying then?
