Why can't we fly straight up into space, let the world rotate beneath us, and then fly down to our destination?

Just wondering if this is possible or at least possibly more economical than flying half way around the world.

The problem is that you're moving along with the earth.  If you fly "straight up into space", you'll still be moving very quickly from west to east.  You'd have to accelerate westward in order to become "stationary", and such acceleration would require more energy than simply flying there normally on an airplane.


If you want an analogy, it's like asking why you can't travel from the front to the back of a bus by simply jumping and letting the bus travel underneath you.
