Welsh Police Chopper Chases UFO

The three airmen described the unidentified flying object as "saucer-shaped", and proceeded to pursue, getting as far as the North Devon coast.

This sighting comes only weeks after the MoD began a full disclosure to the public of its UFO-files, in which they state that even air traffic controllers and police officers have seen mysterious craft in the skies over Britain.

The helicopter was stationary, hovering at 500ft and waiting for clearance to land on June 7, when the crew spotted the UFO hurtling towards them from below.

"They are convinced it was a UFO. It sounds far-fetched, but they know what they saw."

According to the South Wales Police, the helicopter crew crossed the Bristol channel in pursuit of the UFO, but lost sight of it and were forced to turn back due to low fuel.

The sightings range from incredible tales of little green men visiting the Wirral to corroborated accounts from policemen and pilots of Unidentified Flying Objects hovering above towns and cities.
