'Richard Sauder, Ph.D., is probably the world's foremost public authority, as well as the first person, to systematically popularize the mysterious topic of underground and underwater bases and tunnels. He is the author of several books and major reports. During the first hour of this program we discuss themes from his book, "Hidden in Plain Sight - Beyond the X-files," an in-depth book on underground bases, combining archival research, on the scene investigation, and first-hand interviews. Sauder takes us into the underground world.'
