The Coming of the Gaurdians

Subtitle: An Interpretation of the Flying Saucers as Given from the Other Side of Life

Compiled by Meade Layne

Where do UFOs really come from? Layne holds an inter-dimensional, etheric based theory. Much of his information was corroborated by the scientific work of Trevor James Constable or came directly from intelligence channeled through Mark Probert, the greatest psychic medium of his time. Layne was scientific in his approach until hearing Probert’s incredible messages, which independently verifies his research.

Covers propulsion systems, vibrational frequencies, and the sudden appearance of these craft more clearly than any scientifically based book could ever do.

The Flying Saucers are Real

Author: Donald Keyhoe

Was the first indepth, authoritative look at the flying saucer phenomenon and is considered to this day to be one of the best books on the subject ever written.

Extremely well researched with facts that were documented, containing none of the disinformation and hype that has crept into the field over time. The author was a retired Marine Corps Major who became an aviation writer, and was therefore perfect for the job of researching and writing this book.

Using his own knowledge and information from friends in the military, he came to the conclusion that UFOs originate from outer space and the U.S. military was engaged in a cover-up.

Includes documented cases with credible witnesses. Much is shown on how and why secrecy was enforced.

Extraterrestrial Entities and Technology Recovery and Disposal

Categories: Booklets, Catalog, UFOs and Extraterrestrials|Tags: |

Author: The Majestic 12 Group

Considered by many to be a Top Secret government document written by and for a secret U.S. group, MJ-12, in 1954, which was later leaked to the public. Contains detailed guidelines for military personnel to follow in the event of encountering and/or recovering extraterrestrial beings or crashed objects.

There have been heated debates about its authenticity over the years and evidence has been presented on both sides of the argument. Due to its shadowy origins, we may never know with certainty if this is a genuine document or an elaborate hoax. Worth reading and investigating for oneself.

30 pages • Size: 8.5×11 • stapled binding Booklet • Price: $9.00

UFOs Do Not Exist

Subtitle: The Greatest Lie That Enveloped the World

Author: Roger Leir

Foreward: Ph.D. Edgar Mitchell

“UFOs do not exist” are not the words of the author, but of government authorities. The evidence found here should once and for all expose this longstanding lie. Are alien beings capable of abducting humans and implanting objects into our bodies that we do not know about? The evidence is the implants themselves – tiny metallic objects of unusual composition, surgically removed from people who claim to have histories of alien abduction. This book presents the most advanced research on the reality of alien implants which the author, an actual doctor, had originally thought was nothing more than a joke. For the first time, revealed in this book, eminent scientists have made legitimate off-world claims and proven them with hard evidence.

Also covers worldwide sightings, an update on the amazing 1996 UFO crash case from Varginha, Brazil, and a revealing Foreword by Apollo 14 astronaut Edgar Mitchell. As this book was going to press, Dr. Leir passed away. We are grateful for his incredible work.

UFO Crash in Brazil

Author: Dr. Roger K. Leir
