The revised and updated edition of this classic title is packed with intriguing cases from the early years of the modern UFO mystery. The book contains 621 pages of numerous UFO sightings, including cases involving RAF aircrew who had spectacular mid-air encounters during the Second World War. As most Ministry of Defense UFO files from this period have not survived, this information is priceless from a research point of view, and is an insight into a fascinating period of history that was previously thought to have been lost forever. This book contains a precise chronology of British and American UFO reports, covering the period between 1939 and 1959. Also included are sightings from the First World War, 1929/1940/1943/1944/1954, and numerous reports by USAF/RAF pilots, many of whom have been interviewed personally by the authors over a 20-year period. It contains many original letters and illustrations; for example, Jessie Roestenberg's UFO encounter in 1954, the Margaret Fry UFO case of 1955, 1956 - RAF Lakenheath UFO sighting, and so much more! The foreword is by world-renown UFO author - Timothy Good, and has comments by Nick Pope (now a personal friend), who was previously on Air desk 2a at the Ministry of Defense - in charge of UFO reports brought to him by the public's attention - and now a leading author of books dedicated to the UFO subject.
