11/03/16; 15 white lights traveling west to east in Charlotte NC at 19:10. 2-3 minutes observing themIn Charlotte, North Carolina (28227) at approximately 7:10pm, on Thursday, 11/03/16, my wife and I observed 15 white lights (circular) moving in formation and they appeared to be independent of each other. They were no brighter than the surrounding stars. They moved from the west going east (75 degrees WNW according to my cell-phone compass). They were directly overhead and appeared to us to be at an altitude of in-flight commercial aircrafts. They traveled as fast as commercial planes at cruising altitude. There was no sound and they traveled in a straight path. There was some position changing within the formation. According to weather.gov, the wind was calm at 18:53 and 5 mph from the SW at 19:53. Our observation was at 19:10. We did not feel or observe any wind.At first sight, I was alone. I saw 10 white lights (round) in a staggered row from left to right with 5 trailing in a 2-1-2 pattern. I went to get my wife so she could see/confirm. This took 15-20 seconds. Upon our return outside, the staggered row contained 12 white lights and three were trailing in a 2-1 pattern. They did not appear to blink, but periodically, a few would indiscriminately fade out then back to full glow. This process took 2-3 seconds. It was a clear, cloudless night. The total observation took 2-3 minutes. The lights were very similar to the lights videoed in Charlotte, NC, on 10/15 and posted to YouTube. . . . . . . . . . .. . . . . . . . . .. . . ... . .
