© Bob AtkinsMystery object caught by dog walker on camera phone
Bob Atkins was using his mobile phone to video his dog as it played in a pool of water at Roanhead on the south Cumbrian coast.
When he later studied the footage he was staggered by what he saw.
The strange event he captured on film lasted barely a second - a second in which a solid looking dark object flashed across the sky at immense speed.
It was only when Bob slowed down the film that he first saw the object clearly. Was it a strange bird?
Perhaps a fault with the camera? Could it even have been some sort a military prototype secretly tested?
Whatever the answer, the images enthralled author Pat Regan, 53, who has written a book about UFO sightings. It includes an account of the Cumbrian incident.
Mr Atkins said: "The object appears in this video for about one second and you have to go into freeze frame to actually see what it is as in normal play it just appears as four black flashes on the screen.
"This was captured on July 23, 2009 at 3.49pm.
"In that one second the last few frames are the few that I think are most significant.
"While filming this at the point where the phenomenon appeared I was facing approximately north."
Mr Regan said he carefully checked the footage and concluded the unidentified object was a "solid entity" with a shiny, light upper surface and darker underside.
He said: "The speed is impressive too and I would estimate the altitude of the object to be something around less than 100ft," he said.
"I believe that we can discount popular sceptical claims for things like camera error, mainly because the UFO takes on a solid obese, saucer-shaped outline and appears to bank over when traveling from right to left in Bob's film.
"The glossy top surface on the UFO shows as it goes out of sight towards the left of the screen.
"It also seems to be flying much too fast and low to be any type of recognised aircraft.
"Some may suggest that the unknown object was perhaps a large insect or bird.
"But on closer inspection of the footage this seems highly improbable. This may leave two distinct possibilities.
"Did Bob inadvertently capture footage of an undisclosed military prototype aircraft, or aerial vehicle or are we witnessing a mysterious craft of an extraterrestrial nature?"
There is a second object that shows up in this video. top middle.
