Air Defense Operations Center Kindsbach (Source: Dr. William Elliott, HQ USAFE) In October 2006, a group of historians from HQ USAFE visited the Kindsbach Cave. The general cave area is covered with dirt and overgrown with vegetation. The two side entrances, however, are still fairly clear. Entrance to the cave is via one of the emergency exits, to the left of the main entrance — which has been covered over. New housing has grown up right next to the cave. The cave is private property and should not be accessed without proper authorization!
