If I sail on a boat from North to South the boat will be dragged by the oceans which it floats on, and the oceans are dragged by the Earth. Now when you go higher let say 10 km an airplane will also be dragged by the atmosphere, so the plane would "feel" an aerodynamic force against the atmosphere (rotating around Earth) if it is stationary.
But when you get higher and higher the atmosphere will get less dense and the force of the atmosphere will drop, till you probably reached satellite level where there is almost no drag of the rotation of the Earth at all.
What is the altitude an airplane can no longer be felt by the pilot or plane effected by"feel" aerodynamic forces because the atmosphere is so thin?
