Final UFO desk files released

The final batch of files from the government's UFO desk, which closed in 2009, have been released.
They include a letter from a schoolgirl in Altrincham, Greater Manchester, reporting a sighting with her dad.
Other reports in the files include a man in Carlisle who thought he was living with an alien, and a man in Cardiff who claimed a UFO took his dog!
The Ministry of Defence shut the UFO desk to save money and because it felt none of the reports proved anything.
