The book includes the claims of the most famous of the Contactees, including George Adamski, who asserted that in 1952 he met human-like aliens from Venus in the deserts of California and George Van Tassel, an aircraft mechanic who asserted that he too had face-to-face encounters with extraterrestrials from our own solar-system. Chapters on the other, major Contactees of the 1950s and 1960s follow, including Daniel Fry, an employee of the White Sands Missile Range, New Mexico, who claimed to have had repeated encounters with human-looking aliens who took him for flights; Truman Bethurum, who is alleged to have become far more than friendly with the female "Space Captain Aura Rhanes,"; George Hunt Williamson, who maintained that he, too, soon became the target of the Space-Brothers'' activities; the elderly Maier sisters, whose mid-1950s claims of being contacted by the Space-Brothers led to secret visits from agents of the CIA; George King, who founded the now-famous Aetherius Society and who went from cab-driver to voice of the Space-Brothers practically overnight; and Sir Peter Horsley, a leading figure in the British military, who said he had face-to-face encounters with a human-looking alien.Also investigated in the book are a detailed look at the FBI''s secret surveillance files on most of the major Contactees and an examination of several of the intriguing notions that have surrounded Alien visitation cases over the years, such as Government mind-control experiments, secret propaganda plans, whether the contactees can be dismissed as ''hoaxers'' and whether the UFO mystery may be the last remnants of an ancient, Earth-based society that move among us masquerading as Aliens.
