Paul Hill was a well-respected NASA scientist when, in the early 1950s, he had a UFO sighting. Soon after, he built the first flying platform and was able to duplicate the UFO's tilt-to-control maneuvers. Official policy, however, prevented him from proclaiming his findings. "I was destined," says Hill, "to be as unidentified as the flying objects." For the next twenty-five years, Hill acted as an unofficial clearinghouse at NASA, collecting and analyzing sightings' reports for physical properties, propulsion possibilities, dynamics, etc. To refute claims that UFOs defy the laws of physics, he had to make "technological sense... of the unconventional object." After his retirement from NASA, Hill finally completed his remarkable analysis. This book, published posthumously, presents his findings that UFOs "obey, not defy, the laws of physics." Vindicating his own sighting and thousands of others, he proves that UFO technology is not only explainable, but attainable.

Could “UFOs” and “Aliens” simply be us, but from the future? This provocative new book cautiously examines the premise that extraterrestrials may instead be our distant human descendants, using the anthropological tool of time travel to visit and study us in their own hominin evolutionary past. Dr. Michael P. Masters, a professor of biological anthropology specializing in human evolutionary anatomy, archaeology, and biomedicine, explores how the persistence of long-term biological and cultural trends in human evolution may ultimately result in us becoming the ones piloting these disc-shaped craft, which are likely the very devices that allow our future progeny to venture backward across the landscape of time. Moreover, these extratempestrials are ubiquitously described as bipedal, large-brained, hairless, human-like beings, who communicate with us in our own languages, and who possess technology advanced beyond, but clearly built upon, our own. These accounts, coupled with a thorough understanding of the past and modern human condition, point to the continuation of established biological and cultural trends here on Earth, long into the distant human future.

An insider's look at the science of near-Earth comets and asteroids Of all the natural disasters that could befall us, only an Earth impact by a large comet or asteroid has the potential to end civilization in a single blow. Yet these near-Earth objects also offer tantalizing clues to our solar system's origins, and someday could even serve as stepping-stones for space exploration. In this book, Donald Yeomans introduces readers to the science of near-Earth objects—its history, applications, and ongoing quest to find near-Earth objects before they find us. In its course around the sun, the Earth passes through a veritable shooting gallery of millions of nearby comets and asteroids. One such asteroid is thought to have plunged into our planet sixty-five million years ago, triggering a global catastrophe that killed off the dinosaurs. Yeomans provides an up-to-date and accessible guide for understanding the threats posed by near-Earth objects, and also explains how early collisions with them delivered the ingredients that made life on Earth possible. He shows how later impacts spurred evolution, allowing only the most adaptable species to thrive—in fact, we humans may owe our very existence to objects that struck our planet. Yeomans takes readers behind the scenes of today’s efforts to find, track, and study near-Earth objects. He shows how the same comets and asteroids most likely to collide with us could also be mined for precious natural resources like water and oxygen, and used as watering holes and fueling stations for expeditions to Mars and the outermost reaches of our solar system.

The ultimate guide to Project Blue Book by one of the lead astronomers for the US Air Force program to investigate UFO sightings. Originally released in 1977, this new edition by the world's foremost authority on UFOs distills 12,000 sightings and 140,000 pages of Project Blue Book evidence into a coherent explanation. A US Air Force - sponsored UFO-basher for years, Hynek had completely changed his tune by the late 1960s. Whether you believe in little green men or an official government cover-up policy, The Hynek UFO Report is required reading. Have UFOs really been reported by every nation across the globe? Can all the eyewitness reports simply be fantasy? Are we victims of mass hallucination or just plain lies? Have close encounters actually occurred? Is the government concealing deep secrets at a hidden location? The Hynek UFO Report is rational, logical, and realistic. It is for anyone interested in UFOs, the possibility of extraterrestrial life, and the role of the US government in hiding the truth from the public.

Long out-of-print, Cramp's 1966 classic book on flying saucer propulsion and suppressed technology is available again. Cramp wrote Space, Gravity and the Flying Saucer in 1954 and was Vice-President of the British UFO Research Association (BUFORA). This is a highly technical look at the UFO phenomenon by a trained scientist. Cramp first introduces the idea of anti-gravity and introduces us to the various theories of gravitation. He then examines the technology necessary to build a flying saucer and examines in great detail the technical aspects of such a craft. Cramp's book is a wealth of material and diagrams on flying saucers, anti-gravity, suppressed technology, G-fields and UFOs.

A complete investigation of the development and suppression of antigravity and field propulsion technologies • Reveals advanced aerospace technologies capable of controlling gravity that could revolutionize air travel and energy production • Reviews numerous field propulsion devices that have thrust-to-power ratios thousands of times greater than a jet engine • Shows how NASA participates in a cover-up to block adoption of advanced technologies under military development In Secrets of Antigravity Propulsion, physicist Paul LaViolette reveals the secret history of antigravity experimentation--from Nikola Tesla and T. Townsend Brown to the B-2 Advanced Technology Bomber. He discloses the existence of advanced gravity-control technologies, under secret military development for decades, that could revolutionize air travel and energy production. Included among the secret projects he reveals is the research of Project Skyvault to develop an aerospace propulsion system using intense beams of microwave energy similar to that used by the strange crafts seen flying over Area 51. Using subquantum kinetics--the science behind antigravity technology--LaViolette reviews numerous field-propulsion devices and technologies that have thrust-to-power ratios thousands of times greater than that of a jet engine and whose effects are not explained by conventional physics and relativity theory. He then presents controversial evidence about the NASA cover-up in adopting these advanced technologies. He also details ongoing Russian research to duplicate John Searl’s self-propelled levitating disc and shows how the results of the Podkletnov gravity beam experiment could be harnessed to produce an interstellar spacecraft.
