Cigar-shaped UFO during a Ziggy Marley concert

On July 15, 2003, during a Ziggy Marley concert in Clarkston (Missouri, USA), several spectators have seen a black cylindrical-shaped flying in the sky… What is it?

Witness report:

I was with friends watching a concert at DTE Energy Music Theater in Clarkston, MI. At around dusk, I noticed something in the NE sky moving in our direction. I noticed the object because it was moving against the backdrop of a clear sky. I wondered about the object immediately because it was moving very fast and coming in our direction. I started tapping my friend on the shoulder and pointing at it and just as he looked up, it passed overhead and kept going in a straight line in a SW direction. We lost sight after it flew by. Later when we left the concert, other concert goers were overheard talking about it and wondering what it was. My observation of the object lasted about 10 seconds. In that duration of time, I estimate the object cleared a distance of 20 miles or more. It was totally black, cylindrical/cigar shaped, and was noiseless. It was very odd to see something of this size fly in a straight path so quick with no wings or apparent means of propulsion.
