What was reported

On 21 August 2004, and again on 31 October 2004, 1 October 2005 and 31 October 2006, hundreds of people in Tinley Park and Oak Forest watched three red lights in a triangular formation hover and drift slowly and silently, and many filmed them. The videos aired on local news, Dateline NBC and the History Channel; some ufologists argued the lights kept a fixed geometry as if attached to a dark object. No official investigation reported on them; skeptics point to the Halloween-season dates and the slow drift and suspect balloons carrying red lights, the technique used in the 2009 Morristown hoax.
