Why can’t helicopters just hover and let the Earth rotate beneath it?
It’s because the air / atmosphere is also spinning. As the earth turns, the air that is in contact with the rough earth surface (buildings, cities, mountain ranges, hills) is dragged along too. And then this in turn drags the rest of the air. So the entire atmosphere is dragged along in earth’s rotation.
