Two lights that looked like sattelites traveled in a line, with one following/chasing other until the both disappeared.Last evening on April 18th, 2014, my 25 year old son from Juneau, Alaska was visiting and we decided to go out in the hot tub and catch a viewing of the ISS at 21:36 Hrs local Pacific Time.The ISS came from the NW on a course towards the SW at about 86* above us. At about a minute into it, I had looked away and my son, ((son's name deleted)), said he saw a light chasing it and it disappeared. I never saw it and thought perhaps he was just seeing the reflection from the Space Station since this was his first time.At about 2200 Hrs, I was looking to the south at about 50* center in front of me facing the south and I had saw a satellite. Make note: Between 21:36 and 2200 Hrs. we had seen at least 10 plus satellites that seemed to be going north to South and South to North passing the Big Dipper. Can’t remember a time when there were so many in the sky in a short time. This satellite I saw in the south was going from SNW to SSE and then I saw what appeared to be another satellite about 3 fingers right behind it. However, these two were going a little bit faster than the normal satellites. I got my son to look and he locked onto them an then it appeared these were lights and the #2 was following in pursuit of the other #1 light. Just as the #2 increased speed and a little distance the #1 light increased speed and disappeared as the #2 light disappeared.I have seen lights do weird stuff, but to see these two lights in the sky that were not lanterns and looked like stars or satellites move through the sky like they did and vanish was an incredible rush to share with my son at my age of 51.Thank you for allowing me to share my observation. Not sure what my son saw, but we both saw this! I just wanted to post this report in case others saw this.
