This book goes inside the real X-Files. Not only have the FBI and CIA investigated UFOs, but both agencies have actively tried to conceal that fact from the public. This book proves it. These agencies collected information which, when combined with evidence collected by Air Force Intelligence, proves that at least some UFOs are interplanetary craft. Furthermore, top Air Force officials knew this over sixty years ago and withheld (covered up?) this information from the American people. Written by Dr. Bruce Maccabee, one of the most respected voices in UFO research, this is a riveting page-turner, packed with information. It tells the real story of why America's leading intelligence agencies have been genuinely concerned about UFOs, and why the "problem of UFOs" is unlikely to go away any time soon.
