The surface of the earth is moving approx. 1000 miles per hour at the equator. Which means, excluding natural wind and especially hurricanes, the air is also moving about 1000 miles per hour along with the surface, or the central areas of the earth would be stripped of just about everything…trees, mountains, water, etc. The poles would get real crowded : >) The earth rotates west to east. Which means all the air is also moving west to east at about 1000mph. If a plane flies 400mph from Calif. to NY and then NY to Calif, does it take more fuel to fly from NY to Calif. against the 1000 mph air? Even just a little bit?
