On 2/6/9 I saw a very fast moving black object with a rounded front and small tail in the sky. It disappeared behind a cloud.On Friday, Jan. 6th, 2009, I was traveling by car from Kansas City, MO to Sedalia, MO along I-470E/US-50E and I saw a fast moving black object in the sky several miles ahead of me. It had a rounded front and a small tail. It caught my attention because of how fast it was moving and its shape. I watched it for approx. 10 seconds before it went behind a cloud. I waited for it to reappear on the other side of the cloud, which it never did.
