This remarkable book tells the story of over 200 years of UFO sightings, drawing on formerly secret reports released to The National Archives by the Ministry of Defence. Original records reveal how British Intelligence and the CIA investigated many Cold War sightings, from the Roswell incident of 1947 to ghost aircraft, Radar Angels to the RAF's confidential files. New light is shed on many famous cases, such as RAF Topcliffe, 1952; the Flying Cross in Devon, 1967; RAF West Freugh, Scotland, 1957; the Berwyn Mountains UFO crash and the Phantom Helicopter Mystery, as well as the notorious 'Welsh Triangle' and the Rendlesham Forest incident. Dramatic witness statements and personal interviews - many undertaken by the author himself - combine with rarely seen photographs, drawings and newly available documents to bring these extraordinary experiences vividly to life. From aerial phenomena of the First World War to crop circles and a secret UFO study of more recent times, The UFO Files offers a unique guide to our most intriguing mysteries.
