This picture was taken in Orland Park, Illinois, yes I was following this UFO for a while and like a good investigator I clicked off as many frames as I could manage while maintaining some control over my mind, my car, and my camera. the UFO was moving like an intelligences was operating this ball of light. After only a few blocks the UFO, or what I thought must be "ball lightning" pulled away from me at a higher rate of speed than before. After thinking about this whole thing after it all took place I think it was responding to me. Just about the time I worked all this out in my head, that this was an intellect and not ball lightning the UFO turned away from my car and seemed to run away into a local school parking lot when, as if it didn't want to be photographed it turned and raced away from me. That's how I was able to get at least one photo of some clarity. The glow under the orb, was shimmering as though it was heat convection rising off a hot strip of asphalt. I could not discern any sound until it streaked away and I heard a whooshing sound like a baseball bat swing in air. I first sighted it as the UFO came up behind me like a traffic cop and chased me for a moment and then instantly it was about 100 yards off my passenger door, paralleling my speed and direction of travel. Gracefully jumping over fence rows and power lines like the read out of an EKG, sharp spike like movement up and down.as I fumbled for my camera, (I always have a camera with me) to get a shot of what ever this was it seemed as though time was slowing down and even stopping briefly as I struggled with the subconscious fears of the unknown and a very real time event unfolding around me like a motion picture. I somehow manage to stop the car in a school parking lot to shoot this thing. I jumped from my car like I had nothing to lose and it was here that it turned away like a shy teenage girl and shot away from me at 10 times the speed it was following me at. As fast as it had covered 100 to 125 yards it stopped, it seemed to spin a little as it just hovered for a second, like a cake on a lazy Suzann, then it took a 45 degree turn up towards space without a sound I can remember unlike anything I have ever seen before or sense in a 10th of a second it was gone. I ran after it shooting wildly into the dark night sky and as fear released a grip on my wits, I almost felt sad it was over... It all happened so fast I almost can't recall the details, the one's I do remember like the time displacement. Maybe it was simply the brain moving in hyper speed as to make an illusion of time slowing down, or could there be the slightest chance of a possibility that I was hit by some kind of revere tractor beam... The world will never know... I couldn't sleep for a few days, and I've been telling this short but unforgettable moment of my life ever scene, confidently I was scared more after, than I was while it was happening...
