Bizarre footage appears to have captured the moment a UFO appears to chase a passenger jet through the sky.
The incident was caught on camera by a baffled resident in the US who has recently uploaded the footage in a bid to get some answers.
The witness told the Mutual UFO Network : "I am told that military pilots train in the mountains around where I live and I’ve always enjoyed seeing them fly through.
"This happens all the time. Jets and helicopters are a common sighting. So I naturally saw the jet and did a double take, because there was something following it.”
