Location of sighting: Des Moines, Iowa, USA
Eyewitness states:
"I was driving east on 35/80 near mile marker 133.6 when I saw a dark disc fly in front of me (right to left) I then saw 2 black helicopters chasing it. I didn't have any feelings, but my first reaction was to take pictures of what I could. I lost sight of the object because I was driving on the freeway."
