I am sure I have said this before, but I will say it again [boast mode on] I once saw the NOSS trio
a group (of which there are a few) of 3 satilites that fly in variable formation, used by the US Navy to triangulate enemy ships at sea - I truly believed I was looking at UFO's or some top secret government formation - I guess that was not too far from the truth, just not so secret anymore!
A site and feelings that will stay with me for quite some time!
Another cool site is when you are watching a satelite and it suddenly 'flairs' as the solor panel directs the reflected sun right at you. It really can be quite bright! You will also notice some satelites 'flash' on and off as they spin round and catch the sun light.
