"All of a sudden as it was coming in, it decided to take off and leave me behind ... The next thing I know it was gone," Torres told Sky News. "It was some kind of space alien craft. It was so fast, it was so incredible ... it was absolutely death defying."

"The blip was burning a hole in the radar with its incredible intensity," the pilot said. "It was similar to a blip I had received from B-52's and seemed to be a magnet of light. ... I had a lock on that had the proportions of a flying aircraft carrier."
