Metaphysical and psychic phenomena have long existed on the fringes of conventional science and academia. That however changed in 1995 when the CIA declassified a top secret program that had been training individuals in 'Remote Viewing' in which, it was claimed, people were able to envision ongoing activities in distant places and future events.
The initial testing was done at the Stanford Research Institute (SRI) where extensive investigations were carried out into the human mind's capacity to transcend all bounds of time and space. SRI's research was supported by the CIA and other government agencies for over two decades. It recognized the inherent psychic potential in humans and attempted to harness these special faculties or 'powers' for the purposes of intelligence gathering, often of a vital nature.
Russell Targ, Hal Puthoff and Ingo Swann were the original founders of this once-secret program. Their task was to learn to understand psychic abilities, and to use these abilities to gather information...they were the original 'Psi Spies' named after the title of Jim Marrs' exhaustive study of the phenomenon. The program eventually came to be called 'Operation Stargate'.
