My father camped out in the backyard with a nine-years-old me, in an army tent that hung like a hammock. Basically we were out at around 8 and saw a row of lights that didn't waver move at all, and it was only a few hundred feet off the ground. Then it vanished. It did not speed off or move away, it was just gone. We checked the time and it was nine ( an hour later) we never mentioned it to other family that I recall, just went inside. Am I crazy or what? This thing we saw was soundless and we saw it in a huge neighborhood, I don't recall anyone else seeing it.
