This book explains exactly how the propulsion system that the majority of Extraterrestrial spacecraft use, really works.This information is shared by an unusually rational and technically minded alien abductee. There are no gaps or hand waving in his explanation. If you have the means to do so, this book will literally give you the knowledge necessary to build a working Gravity Amplifier in your own garage. That seems like a big claim, but read it and see for yourself.There is a chance that this book may get banned, but hopefully by then it could be too late. It is the author's hope that this information will change the world for the betterment of all mankind.
