On November 7, 2006, at approximately 4:15 PM, at least 12 United Airlines employees and additional witnesses observed a dark grey, saucer-shaped object hovering approximately 1,400 feet above Gate C17 at O'Hare International Airport in Chicago. The object reportedly punched a hole through the overcast cloud layer as it departed at high speed. Despite multiple credible witnesses including pilots and mechanics, the FAA refused to investigate, attributing it to a 'weather phenomenon.' The agency initially denied having any reports of the incident until a FOIA request revealed they had documented witness statements. The story became the most-read article in Chicago Tribune history.
