Wolfgang Wuermel, owner of the Kindsbach Cave, briefs

Wolfgang Wuermel, owner of the Kindsbach Cave, briefs members of the 603rd Air and Space Operations Center during a tour of the Air Defense Operations Center bunker, Aug. 16, 2013, Kindsbach Cave, Germany. The bunker was built prior to World War II and was utilized for command and control operations for the German army. After the war it was passed to the French, who used it primarily for storing munitions. The U.S. Air Force gained control of the bunker in 1954 and turned the bunker back into a command and control center where air operations could have been led if the cold war turned hot.
