I was driving and I thought I saw a large bird but it was larger and black and was like a helicopter but more smooth moving. It Was over Fort Detrick Then I noticed a shiny disk moving in a slow hovering way. It definitely wasn't a normal plane pr helicopter. So I pulled over on a side street to watch it. It was moving slowly above the tree tops. Then. It was really high up and looked like a Star. Only it was 2 pm. It was staying in the same place and I had things to do, so I left. I tried filming it but couldn't really see it on the camera. My eyesights not too good. But it's does pass through real quick in one of my videos. I didn't feel anything in particular. Calm enough. Curious. I thought it might be a drone or some government vehicles. I can't upload my film right now, but if you have an email where I can send it. I'll do that.
