The New Google Earth not only has space in it but it also has a secret flight simulator. It is really neat to fly over real terrain.

When you run Google Earth and get the Earth on the screen, just click on the earth to make sure you are in google earth, now just hold
CTRL+ALT+A

You will get a popup asking you to select from 2 planes and which airport, the joystick worked and it is a very forgiving flight simulator which is nice as it allows you to look around at the scenery.
