Clusters of up to 100 mysterious objects, bright white lights and strange, triangular shaped objects are just some of a huge surge in UFO sightings reported to the Ministry of Defence last year. The ministry has opened up its own X-Files" for 2007, revealing 135 UFO sightings from across the UK. The number of sightings has shot up since 97 were reported in 2006. In Duxford, Cambridgeshire on April 12, a witness reported seeing fifty objects, each with an orange light, assembling in the sky before ascending. Two pilots in different planes above Alderney in the Channel Islands reported the same UFOs on April 23. They saw one bright orange craft, then a gap, followed by an identical object. In the West Midlands in December, one witness got a shock when a UFO shone a light into her window. Hilary Porter, from the British Earth and Aerial Mysteries Society (BEAMS) said sightings were becoming increasingly common. She said: "There has been a huge influx of UFOs. Absolutely enormous. There [have] been these huge formations that have been coming. We have had call after call after call, from business people right down to ordinary folk in their cars. There have been some very close encounters that have been quite unnerving for the people involved. We have had other people reporting orb sightings." A spokeswoman said the ministry does not investigate each and every report. "We only investigate if there have been any objects in British air space that may be military," she said. "Unless there's evidence of a potential threat we don't investigate to try to identify it."
