I was sitting at my computer, waiting for it to boot, and I leaned back in my chair to look at the cloudless evening sky through the skylight directly overhead. We are generally surrounded by trees, so this is one of the few areas at my home I can see the sky. The skylight is large, about 4��� x 4���. While looking at the sky, I spotted two small dots of light (craft?) moving due east directly west. They were side by side, and appeared to be very close together. They appeared to be at a very high altitude, and were incredibly fast. The two lights crossed my field of view, which is about 50 degrees, in less than two seconds. Just before moving out of my view, the two lights cris-crossed paths, but continued on the same vector. About one minute later, I saw a similar light(craft) moving at similar altitude/speed from NNE to SSW. The lights reminded me of videos I���ve seen of space debris re-entering the atmosphere, but there were no contrails of any kind, and I���ve never seen pieces of debris cross paths and keep going the same direction. VERY interesting!
