Mock UFO with a sign reading \'Smile, you are being abducted\' north of Brasilia Britain\'s defence ministry shut down its UFO unit four years ago after concluding that extra-terrestrials likely did not exist, and in any case did not pose a threat, previously secret files released Friday showed. The Ministry of Defence (MoD) closed its hotline in 2009 despite a trebling of reported sightings of Unidentified Flying Objects (UFOs) that year, many of them near national landmarks.
In a briefing for then defence minister Bob Ainsworth, civil servant Carl Mantell said the UFO desk was using up increasing amounts of staff time but had \"no valuable defence output\".
He wrote in a memo that in more than 50 years, \"no UFO sighting reported to (MoD) has ever revealed anything to suggest an extra-terrestrial presence or military threat to the UK\".
It added: \"The level of resources diverted to this task is increasing in response to a recent upsurge in reported sightings, diverting staff from more valuable defence-related activities.\"
