This is very interesting:

Video information:

I caught this weird looking ghost white UFO today May 11, 2012 at 3.40PM over Chicago IL. I am West of this blob of energy looking East toward the Downtown sky, the UFO was flying NW to SE. Sorry bout all the shake when I super zoom in, ive to learn to not zoom in so much next time. I tried to stablize the video the best I could. It was very bright out this thing was pretty high up so it was hard to capture it smooth esp thru a 3 inch LCD screen. 3 mins of video and 3 mins of enhanced (edge detection, threshold, light flitered) still photos from the video. Watch in 1080 HD!
