Wow! Just found out about J-Pass 2.0, which apparently has been around for awhile. It shows you when and where satellites will be passing over your head. Even more impressive is J-Track 3D which gives you a rotateable globe showing 500 satellites. Click on a satellite and its orbit shows. Very cool!
There must be a WebQuest one could wrap around this one. How about linking this to a database of UFO reports?
