VISITORS FROM SPACE

From Amazon: This astonishing new bestseller from the author of the sensational "Flying Saucers - Serious Business" provides answers to the most frequently asked questions about UFOs: -Where do they come from? -Is it true that they are often tracked on radar? -Has anyone actually talked to UFO pilots or taken a ride in a flying saucer? -Who was the first astronaut to see a UFO in orbit? This collection of well-documented reports of UFO sightings, presented by America's most popular paranormal radio personality, Frank Edwards, covers the gamut of ufology, including: -The Brazilian farmer who was twice seduced by a beautiful blonde spacewoman... -The New Hampshire couple who were kidnapped, probed, and interrogated by the space visitors... -The California mystic who has met with the outer space people several times, and photographed their ships... -The newest hoaxes, kooks, and hard-to-believe tales in print! "Flying Saucers - Here and Now" presents startling new evidence that UFOs really do exist, and presents UFO sightings by: a Florida governor; scores of police officers; a Maryland newspaper editor; a Texas bank president; a Kansas police chief; a New Orleans colonel; two Australian constables; members of the Royal Canadian Air Force; as well as psychologists, airline pilots, scientists, and top executives. From the book's forward by the author: This is the chronicle of recorded events in the fascinating field of Unidentified Flying Objects in the past sixteen months. If the evidence constitutes what it seems to indicate, the presence of the UFOs amounts to one of the greatest news stories of all time and, as a professional newsman for more than forty years, I have tried to deal with it as such.

A group of children discovers a flying saucer in the sky and is taken on an alien adventure, but can they figure out a way to get home?

Speculation on the origins of flying saucers and their historical role in ancient writings. Mr. Adamski also describes his encounter with a being from another planet.

John Mack explored alien encounter experiences deeply, revealing a world of meaning and power that can revolutionize our understanding of who we are and our place in the cosmos. Dr. Mack suggests that such experiences reveal to us a universe which is filled with intelligence and life, though this may not always take the densely embodied form with which we are most familiar. This book brings us to the edge of material reality and beyond, shattering the boundary that has separated matter and spirit and scientific or spiritual ways of knowing. Dr. Mack asks us to move beyond the largely useless debate about whether UFOs or abductions are real in a purely material sense. He shows us the limited way that we have used ourselves in learning about the cosmos, and challenges the limitations of traditional science as a way to learn about the multi-dimensional world in which we reside. Insights about the relationship between spiritual and physical energy; trauma’s role in transformation; information about the ecological crisis facing the planet and the urgency that we do something about it; the possibility that human beings are participating in the creation of some sort of interdimensional hybrid race; the expansion of human consciousness and our spiritual reawakening; and the apparent evolution of extraordinary relationships that some human beings may be developing beyond the earth plane — these are the matters this book includes. Dr. Mack demonstrates that the investigations of a skilled clinician, exploring human consciousness through in-depth conversations, can reveal to us a multidimensional, apparently intelligent, cosmos whose nature is fundamentally consistent with the discoveries of leading scientists who have been gaining knowledge primarily through exploring the physical world.
