This segment is talking about underground facilities in Southern Cal. They are run by our large defense contractors. Also time is spent reviewing Tube technology from the Nazis (World War II time-frame). This was probably the basis of the present day tunnels between the underground bases, thanks to Project Paper-Clip.
Enjoy the plot thickens.
