'Mile high mystery' in Denver

DENVER -- One Denver man captured images of this crazy UFO on his camera from high atop a hill in Denver Colorado.

He says the object appears a few times a week always around noon.

CNN didn't believe the guy, so they sent their own camera man to try and capture the object and he did.

"That is not an airplane, that is not a helicopter, those are not birds. I can't identify it," said Steve Cowell, Aviation expert. "As it fits the definition, it's an unidentified flying object."

Norad's command center reviewed their records and they noted they did not have any noted air activity in the Denver area during the times this video was recorded.
