I saw something like this tonight. I thought it was a cloud at first , but I was moving a lot faster then a cloud. It was a pretty calm evening too. I thought it was possibly a flock of geese, but I watched it until it disappeared. I then saw another one about 5 minutes later come from the same direction only this one was much smaller. I saw a third one after that come from a completely different direction and it was smaller the the first two. It almost looked like anew outfielder of a ghost floating in the dark sky!
