Your story reminds me of when I was about eight or nine back in the early 70s. We lived in Illinois and one evening I was looking up at the sky and suddenly saw what appeared to be a star quickly move from one spot in the sky to another and then stop dead. Soon, another one did the same thing, followed by another. All were at first sitting perfectly still, then moved extremely fast (several degrees of arc in less than a second), and then sat perfectly still at their new locations. A few years later I was sitting in a theater watching Close Encounters of the Third Kind, when the final scene at Devil’s Tower began. There’s a moment when several UFOs join together in formation and disguise themselves by imitating the Big Dipper. My jaw dropped, because it was so much like what I saw.
I saw the same thing around 1971 from my back yard in WA state. I had time to get my Mom, Dad, and 5 brothers and sisters to watch the show.
