UFOs might be out there, but they are not a threat to the UK. That is the official reason why the UFO hotline was shut down at the end of November last year as the Ministry of Defence looked to cut costs.

Professor David Clarke at Sheffield Hallam University says that he received the explanation from the MoD after putting in a Freedom of Information request – only to discover that the MoD is now destroying all UFO reports it receives after 30 days, just so that it doesn’t have to respond to such requests in future.

“Reported sightings…should be answered by a standard letter and, on the advice of Corporate Memory and The National Archives, should be retained for 30 days and then destroyed, largely removing any future FOI liability and negating the need to release future files post 30 November 2009,” says the MoD document.
