An expert in aviation industry told Fox31 Denver that he was not familiar on a flying object caught on video by photojournalists and civilians.
A man from Denver has been shooting the flights which usually take off on noon or 1 p.m. a number of times in a week and the same strange event documented by Fox31 photojournalist.
Steve Cowell, an expert commercial pilot, told Fox31 that the object was not an airplane after watching the video. He added that it was not a helicopter, or even a bird, or insect. He described that the object moved faster than any known aircraft. Cowell said that it was an unidentified flying object.
The Federal Aviation Authority (FAA) said to Fox31 that they did not notice the activity of reported UFO either visually or on their radar displays.
North American Aerospace Defense Command (NORAD) also did not observe the strange activity in Denver during the time of reported UFO sightings.
