This footage shows the moment a speeding UFO flew through the air in the wake of a huge RAF Vulcan aircraft.
The footage – shot close to a nuclear power station – shows the small circular craft hurtling overhead.
Witness Elaine Costello shot the footage.
She said: “The object appears right after the Vulcan bomber has gone out of sight. It flits from the left of the screen to the centre where the video ends.
“I have slowed the video down and the object goes behind cloud briefly. I took stills from the video and zoomed in. The results are interesting. At least one other person saw the object.”
A photo of the UFO was shown to expert Malcolm Robinson ,founder of Strange Phenomena Investigations, who said it “certainly has the classic flying saucer shape.”
“This for me, is one of the few times that a photograph have excited me and I would love to enquire more from the photographer,” he said.
