I just got off work and got home at 3:30 AM. I always look up at the stars before going in my house. A circular shaped object (I could see the outline of it against the stars) came over my house going west and curved fast and shot straight north. It was totally silent. It seems to be flying higher than a small plane coming into the airport would be. Airport is approximately 7 miles west of my house. Gave me an eerie feeling.
