It has been a long time ago and I've tried to get help. It was early Saturday morning. I was going to Lansing iowa, was going duck hunting later. Anyway, I was going around a curve when the sky lit up. It was south of me, a blue white tongue of fire, kind of reminded me of when you see a rocket land, how the flame come out the bottom. I could see this thing slowing down as the intensity of the flame increased. This thing slowed down to almost not moving and disappeared behind a ridge and trees. This thing was at least a mile away. It was big. Sorry, that's all I can remember. I did contact the Postville pice to inquire as to whether a plane crashed and was told no. I know I saw something. I'm a U.S. Air Force veteran, and because of my security clearance and the office I worked in, I've seen the real Blue Book!
