Please don't call me "crazy".
Whatever it was... I won't call it a "UFO" because that has a certain "spacey" connotation. I won't call it a "flying saucer" because it didn't look like a saucer. It just looked like a cluster of lights.
I was driving home, down a country road. It was about 10:30 at night, so it was dark. Off to my left there was nothing but a farmer's field. As I came over a slight rise in the road, I saw a cluster of lights hovering over the field, at an altitude of a couple hundred feet. It was too high to be farm equipment and too low to be a plane. I pulled over to the side of the road to stare at it, trying to figure out what it could be. It didn't move, just hovered there in place. Suddenly it took off... it took off, making a wide circle in a clockwise direction. It took off at such a high rate of speed that my eyes could hardly keep up with it. Within a second or two it had circled the entire visible sky and disappeared beyond the far horizon.
That's all there was to it. It happened 25 years ago. I still have no idea what it was. The most unbelievable thing was how fast it moved, traveling across the sky in a second. It reminded me of the scene in the first "Star Wars" when they put the ship into warp speed and it just zipped out of sight. I can't think of anything to explain it. Yes, it seemed to be flying. No, I couldn't identify it. So, I guess it was an "unidentified flying object". I know how that makes me sound. But it happened.
