String of lights that look like stars, traveling at fairly slow pace, and then disappeared someone else, in Graniteville had to seen i

There was no lights in my town due to a power outage fairly large town. I tried to record what I saw, but it was a string of 20 to 30 lights in the sky much brighter than stars, and they were just going like a train for 25 to 30 seconds then they just totally disappeared. I tried to record my phone would not pick it up. It’s something I’ve never seen. Looked liked a plane, pulling a banner but it was so bright, and then just disappeared one by one in sequential order no clouds at all in the sky I could see every star. I don’t know what that was but it was nothing I’ve ever seen, but it was big or a lot of them.
