First there was Keyhole, downloadable for $ .. then  we got most features (albeit in lower res) for free on Google Maps.. now here’s the super-program:  Google Earth.

Fly in Space, zoom in to any location, get local info, 3D sightseeing ..etc.   Wow!

And what a surprise, this is not a web-app, it has to be downloaded/installed on a local PC.

Bill Gates beware!
