OK a few thoughts.

Airplane speed is usually measured in "ground speed"?

At the equator, the earth is moving (rotating) at about a 1000mph. They don"t get 1000mph winds?

Wouldn"t you be able to fly round the earth in a day, simply by hanging up there and waiting for the earth to move? That might mean that a hot air ballon is supersonic?

Atmosperic changes do not occur cyclically at 24 intervals. Like the weather from the other side of the world (at your lattitude of course!).

Doesn"t happen does it?

These few simple observations (and a lot more possibilities) might help you to answer your own question.
