DENVER (CNN/KDVR) - Something "unidentified" has been spotted in the skies over Denver.
A local resident shot video from a hilltop north of the city. His camera captured fast-moving objects that appear around noon at least a few times a week.
A local news cameraman set up in the same spot, and got similar video.
"That is not an airplane, that is not a helicopter, those are not birds. I can't identify it," said aviation expert Steve Cowell.
The FAA and NORAD both say they know of no aircraft in the area at the time the videos were shot.
