Book excerpt: Remote Viewers is a tale of the Pentagon's attempts to develop the perfect tool for espionage: psychic spies. These psychic spies, or "remote viewers," were able to infiltrate any target, elude any form of security, and never risk scratch. For twenty years, the government selected civilian and military personnel for psychic ability, trained them, and put them to work, full-time, at taxpayers' expense, against real intelligence targets. The results were so astonishing that the program soon involved more than a dozen separate agencies, including the CIA, the Defense Intelligence Agency, the National Security Council, the FBI, the National Security Agency, the Secret Service, the Navy, the Army, the Air Force, the Joint Chiefs of Staff, the Drug Enforcement Agency, the US Customs Service, the US Special Forces Command, and at least one Pentagon drug-interaction task force. Most of this material is still officially classified. After three years of research, with access to numerous sources in the intelligence community--including the remote viewers themselves--science writer Jim Schnabel reveals the secret details of the strangest chapter in the history of espionage.
