Here's another compelling case of a ufo sighting:
"At approximately 16:15
CST on Tuesday, November 7, 2006, federal authorities at
Chicago O'Hare International Airport received a report that a group of twelve airport employees were witnessing a metallic,
saucer-shaped crafthovering over Gate C-17.
The object was first spotted by a ramp employee who was
pushing back United Airlines Flight 446, which was departing Chicago for
Charlotte, North Carolina. The employee apprised Flight 446's crew of the object above their aircraft. It is believed that both the pilot and co-pilot also witnessed the object.
Several independent witnesses outside of the airport also saw the object. One described a "blatant" disc-shaped craft hovering over the airport which was "obviously not clouds." According to this witness, nearby observers gasped as the object shot through the clouds at high velocity, leaving a clear blue hole in the cloud layer.
[1] The hole reportedly seemed to close itself shortly afterward.
According to the
Chicago Tribune's Jon Hilkevitch, "The disc was visible for approximately two minutes and was seen by close to a dozen United Airlines employees, ranging from pilots to supervisors, who heard chatter on the radio and raced out to view it."
[2][3] So far, no photographic evidence of the UFO has surfaced, although it was reported to Hilkevitch that one of the United Airlines pilots was in possession of a digital camera at the time of the sighting and may have photographed the event."==========
