Black triangle (UFO)
Three red lights hovered in a triangular formation were seen by several witnesses in Tinley Park and Oak Forest, Illinois, on August 21, 2004, two months later on October 31, 2004, again on October 1, 2005, and once again on October 31, 2006. The lights were captured on video by some witnesses. According to some ufologists, the video evidence suggests that the lights kept the geometrical shape and moved as if they were attached to each other through a dark object. The incident was examined in a "Dateline NBC" episode on May 18, 2008, and in the episode "Invasion Illinois" of the television series "UFO Hunters" premiered on The History Channel on October 29, 2008.
