The UK’s National Archives (TNA) has just released the largest batch of UFO files to date, which you can download free until 2 April.
Over 8,500 pages of UFO sightings, discussions and reports show how UFOs were discussed by governments around the world. The files contain a wide range of UFO-related documents, drawings, letters and parliamentary questions covering the years 2000-2005.
You can find out more about the House of Lords’ debate on UFOs, a flying saucer hoax that was treated as a potentially real alien invasion of the UK and how 1978 nearly became ‘the year of the UFO’. Start by reading TNA’s highlights guide to help you navigate your way through the files.
