A fleet appeared flying northeast in the sky equidistant apart, some looping back. We have 5-6 mins of video

I was sitting outside star gazing when I noticed a series of cigar-shaped objects flying northeast in the sky. They flew at a steady pace, equidistant from each other. There was one that was much brighter than the rest that seemed to hover overhead. I immediately ran to get my phone but I was out of space. I texted my neighbor and then immediately banged on her door. She witnessed it and grabbed her phone and recorded the last 5-6 minutes of it. At one point they seemed to circle back resuming effortlessly in line. Then it was done and then the last one followed and they just disappeared in the distance. They were not planes, there were no navigation lights.
