reports that The History Channel debuted an episode of "UFO Hunters" October 29 that featured one of the best-documented UFO "sightings" to date. It took place August 21, 2004, when fans were leaving an Ozzfest concert that took place First Midwest Bank Amphitheatre in in Tinley Park, Illinois.
As the fans were caught up in a traffic jam, three lights in a triangular pattern hovered above them for nearly 20 minutes. According to a Chicago UFO expert, it may be the most-seen incident recorded.
Much of the episode was filmed beneath the roof of the venue, where the show's hosts and guests reported their information. It is not known if any of the staff of the once-Tweeter Center saw the UFO in question.
