There were 7 or 8 very bright, small but hazy lights that were separated slightly but quickly lined up behind one another. Traveling northbound maybe 250-300 knots. Once they lined up the craft appeared to be dark gray, rectangular and slowed down once the lights lined up. Seemed relatively close to the earth, so we suspected drones at first. There was no noise though, and the area we were at became quiet as well. No wind or crickets or sirens or dogs barking. Watched it for about 10 minutes until it traveled out of sight.
