Google Earth Flight Simulator

Sorry if this is already old news, but I just found out that Google Earth has a flight simulator feature. It comes with two aircraft options, a F16 Viper and the SR22 4 seater. Instructions can be found here:

Yeah it is very cool, and some people say that this feature is actually a hidden beta for a competitor to MS's flight simulator.

Anyway it is nice as in the "game" you see real landscapes from satellite images.
