In the sky above Chillicothe, OH, we saw four lights. It was after 11 pm so it was pretty dark. The sky was clear and my friend who is an avid ametuer astronomer was outside stargazing. He came running in the house to say I needed to go outside and see these strange lights in the sky. There were 4 lights they were traveling extremely fast. It seemed as though they were as high as the helicopter/planes that were flying were. They went way to far in any direction to be r/c quadcopters and performed maneuvers that were way past the capabilities of normal planes or helicopters. The flew out of our frame of vision 3 times and then came back into it we had a pretty unobstructed view for miles in any direction. The lights they emitted were really faint and were hard to see if another light source was present. Immediately following the "ufos" There were aircraft flying in what appeared to be a grid pattern in the area. They were super silent aircraft and we! re flying an obvious grid pattern one coming in a minute or so after other was out of sight. I am an avid drone / quadcopter enthusiast and there is no way thats what these were they were flying way to close in way to erratic of a nature to be quadcopters and not hit one another. They reminded me of fireflies playing with each other, except at 30,000 feet. The lights were to faint for my cell phone which is all i had on me to get the objects, but I did get video of the flashing lights of the aircraft that moved in afterwards.
