Book excerpt: This is one of the most important books ever written on the clandestine world of the UFO cover-up. Grant Cameron and Scott Crain do more than demonstrate the reality of an extraterrestrial presence on Earth. Through tenacious investigation and impeccable research, they shine a light into the CIA, NSA, Air Force, Navy, and other inside groups that have managed this secret for decades. Their conclusion is inescapable and shocking: this is a secret that the insiders themselves struggle to understand and contain. "Government agencies, at various times, perceive a need to release some UFO information to the public. Some, definitely not all. How do they do it? Always via avenues that leave no one at risk. That means ensuring there is no direct connection between the agency and whomever is doing the actual releasing. It also means the necessity of mixing in some false information. It means, ultimately, to tell the truth, but tell it with a slant. Until there is a full disclosure of the UFO/ET reality, deniability will remain paramount to those in possession of this great secret." - By the authors, from the book's Introduction.
