The UFO phenomenon remains one of the most persistent and perplexing mysteries of modern times. Encounters have occurred for centuries, and reports continue to come from around the world every year. UFOs and Aliens describes the exciting history of supposed extraterrestrial activity on planet Earth. The book documents such famous cases as that of the Washington Nationals; UFO landings and abductions, including the case of the Hopkinsville "goblins"; the enduring mystery of what crashed near Roswell, New Mexico, in 1947; and much more. Everything from infamous hoaxes, to alien implants, to government cover-ups is documented here with the best evidence available, so that readers can decide what may be fact and what is, indeed, science fiction.Dennett, Preston is the author of 'UFOs and Aliens', published 2008 under ISBN 9780791093849 and ISBN 0791093840.
