HIDDEN EMPIRE: UNDERGROUND BASES AND TUNNEL SYSTEMS, with Dr. Richard Sauder. One of the most mysterious and secretive developments of the 20th Century was the coming together of the Cold War, extraterrestrial related phenomena, the national security infrastructure and advances in digging and tunneling technology.

The author of Underground Bases and Tunnels: What is the Government Trying to Hide? will present a packed lecture on the extraordinary proliferation of underground military, intelligence and agency facilities, the relationship to the black budget and possible relation to extraterrestrial phenomena.
