I saw one driving on my way to school one morning.
I was going north on highway 159 through Fairview Heights, IL (a dense commercial district), and I came to a red light. I noticed something out of the corner of my eye on the left side in the sky, several hundred feet in the air. I didn't think too much of it since we do have Scott AFB close by, and Lambert Airport in St. Louis, so we tend to see aircraft going by on their final approach. But I glanced again, since something was clearly odd about this thing in the air.
I made out a disc-shaped saucer gliding in the air, going north, the same direction that I was going. The light turned green, and so I drove further, trying my best to pay attention to the road, but also letting this image start to sink into my brain what I was looking at. This was most certainly a UFO.
As I passed other intersections, parking lots, I realized that I wasn't alone. Several people were getting out of their cars, pointing up in the air, looking awestruck. Nobody knew what the H that was.
It was black, shiny, and looked to have three distinct circles underneath it. I rolled down my window to peek my head out (yes, while I was driving, don't do that
)........and it wasn't making any noise. It was just gliding along at a speed to where I had to slow down a bit to stay at the same pace.
By the time I got to the intersection of highway 159 and interstate 64/40, the UFO turned sharply and headed east, and then sped out of sight. Seriously. It just took off without making any sound at all.
Needless to say, I had a difficult time concentrating in class that morning.
I have NO idea what that was, only that I haven't seen anything before or since. I don't know if it was aliens, mass hallucinations, experimental aircraft or that I was completely absorbed into my own imagination (LOL). All I know is that it was certainly weird.
