Since google clearly doesn't have enough products or features I am never surprised to find new features. The latest one (sent to me by a fellow google fanatic) is a feature for Google Earth. If you have never used this program than I feel pity for you. It is like a souped up Google Maps. You can explore any part of the earth or galaxy in 3D and spin the world, search for locations, tourism info, pictures, real estate, 3D buildings etc.
Anyway, this latest feature is a flight simulator for Google Earth. It allows you to fly around the world in your choice of a F-18 or a Cessna.
I guess the graphics are already there so why not eh......?
