This is the fourth volume in the "Forbidden Science" series, consisting of the diaries of a scientist who is passionate about research into frontier topics including UFOs and paranormal experiences.

Journals of personal research written from 1980 to 1989 by a French-born astronomer and computer scientist interested in UFOs and paranormal phenomena.

Two high-tech executives from Silicon Valley witness unexplained phenomena while on vacation in Brazil. They become the targets of a classified project ready to kill them to capture their data.

In DIMENSIONS, the first volume of a trilogy, Dr. Jacques Vallee reexamines the historical record that led to the modern UFO phenomenon and to the belief in alien contact. He then tackles the enigma of abduction reports, which come from various times and various countries, as well as the psychic and spiritual components of the contact experience. In the last portion of the book, he notes the factors that inhibit research into the phenomenon--the triple coverup and political motivations--and concludes that the extraterrestrial theory is simply not strange enough to explain the facts.

Personal diary of a scientist exploring the frontiers of research

Personal diary of a researcher at the frontiers of science.

Too many cases of "accidental" alien contact...UFO cults praying to the skies...secret "psychotronic" weapons for bending the human mind. The evidence Jacques Vallee reveals, after many years of scientific investigation, adds up to something more menacing than monsters from outer space. Messengers of Deception documents the growing effect of UFO contact claims on our lives and of the belief systems prevalent in our society. It explores the hidden realities of the cults, the contactees, the murky political intrigues and the motivations of the investigators. "As suspenseful as a Hitchcock Thriller, brilliantly argued . . . a smashing achievement." - Robert Anton Wilson

One of the most ambitious works of paranormal investigation of our time, here is an unprecedented compendium of pre-twentieth-century UFO accounts, written with rigor and color by two of today's leading investigators of unexplained phenomena.
In the past century, individuals, newspapers, and military agencies have recorded thousands of UFO incidents, giving rise to much speculation about flying saucers, visitors from other planets, and alien abductions. Yet the extraterrestrial phenomenon did not begin in the present era. Far from it. The authors of "Wonders in the Sky" reveal a thread of vividly rendered-and sometimes strikingly similar- reports of mysterious aerial phenomena from antiquity through the modern age. These accounts often share definite physical features- such as the heat felt and described by witnesses-that have not changed much over the centuries. Indeed, such similarities between ancient and modern sightings are the rule rather than the exception.
In "Wonders in the Sky," respected researchers Jacques Vallee and Chris Aubeck examine more than 500 selected reports of sightings from biblical-age antiquity through the year 1879-the point at which the Industrial Revolution deeply changed the nature of human society, and the skies began to open to airplanes, dirigibles, rockets, and other opportunities for misinterpretation represented by military prototypes. Using vivid and engaging case studies, and more than seventy-five illustrations, they reveal that unidentified flying objects have had a major impact not only on popular culture but on our history, on our religion, and on the models of the world humanity has formed from deepest antiquity.
Sure to become a classic among UFO enthusiasts and other followers of unexplained phenomena, "Wonders in the Sky" is the most ambitious, broad-reaching, and intelligent analysis ever written on premodern aerial mysteries.

In CONFRONTATIONS, the second volume of a trilogy, Dr. Jacques Vallee personally investigates forty astonishing UFO cases from around the world. He finds it shocking that professional scientists have never seriously examined this material. This book is about the hopes, experiences, and the frustrations of a scientist who has gone into the field to investigate a bizarre, seductive, and often terrifying phenomenon reported by many witnesses as a contact with an alien form of intelligence.
