As far as investigators know, the mystery object did not show up on radar Monday.

Investigators believe this object, whatever it is, could pose a serious safety hazard to planes.

Radio transmissions from LiveATC.net confirm a nervous-sounding pilot reported a strange object at 5:17 p.m. Monday.

The pilot is heard telling air traffic control: "A remote controlled aircraft, or what? Something just went by the other way ... About 20 to 30 seconds ago. It was like a large remote-controlled aircraft."

The corporate jet, a Cessna Citation 525 CJ1, was flying at 8,000 feet above sea level over Cherry Creek when the mystery object came close enough to make any pilot nervous.

"That's an issue because now we have something in controlled airspace that poses a danger," Former NTSB Investigator and 9NEWS Aviation Analyst Greg Feith said.

Feith listened to the air traffic recordings and believes the object could be one of three things:

- A military or law enforcement drone.
- A remote controlled aircraft.
- A large bird.

"Was this an unmanned vehicle that was part of some sort of law enforcement operation? Was this somebody that had flown a large model aircraft inadvertently into the airspace? Or was it just [a bird that] caught the pilot's eye so he believed it was an aircraft but could have been a very large wing span bird," Feith said.

Any one of those things can be catastrophic if it collides with an airplane.

Three years ago, a bird strike took down a commercial airliner that managed to land safely in the Hudson River. All the passengers survived.

FAA spokesman Mike Fergus says investigators will talk to the pilot and look at other clues.

"The threat is there from a collision standpoint. We'll do as much as we can here to try to track back what time it was. Probably talk with some remote-control clubs, that type of thing," Fergus said.

The mission of investigators now is to identify that mystery object before another close call, or worse.

9Wants to Know has reached out to sources in the military, local, and federal law enforcement.

So far, nobody has been able to tell us if a drone was flying over Denver.

We also called local airports and model aircraft clubs.

John Dickens, president of the Denver RC Eagles, says members are not permitted to fly more than 400 feet above ground level or about 5,700 feet above sea level, due to possible air traffic interference with Centennial Airport. Dickens said he would look into the incident.
