I observed the line of lights after i took my dog out . the lights were uniform and to the right of the north star. i pulled out my phone and took 1 picture and one video. the video was too dark but the picture come out ok. i ran inside and told my teenage kids to get outside asap. we all went out our front door and watched the entire line of lights fly over our house and off to the south. no noise at all. we have an airport about 5 miles away and often have planes around often. we all were amazed at the silence. the last lights were a pair at the end of the line...Very close to each other.
