Chicago O'Hare Airport Sighting (2006)

In November 2006, United Airlines employees and pilots at Chicago O'Hare Airport witnessed a metallic, disc-shaped craft hovering silently over a terminal gate. The object shot vertically upward at high speed, punching a clear hole in the cloud cover. Despite an official FAA explanation attributing it to weather, numerous credible witnesses and the lack of a conventional explanation make this one of the most intriguing modern UFO cases.
