United Airlines Staff See a UFO at O'Hare Airport?
	A number of employees on a United Airlines flight claim that on November 7 they saw "a spinning disc-shaped object" with no lights hover over O'Hare Airport before flying up through the cloud cover. The object did not show on radar.
	Whatever was seen has been attributed to weather phenomena or airport lights on the clouds. The incident is not being investigated by the airline or the FAA. The FAA does admit that the control tower was queried over the alleged sighting.
	Craig Burzych, a controller at O'Hare, found the incident amusing, saying, "To fly 7 million light years to O'Hare and then have to turn around and go home because your gate was occupied is simply unacceptable."
