GETTY IMAGES At the interior entrance to the Cheyenne Mountain headquarters, two military personnel exit the administrative area. The personnel work at 7,000 feet inside the granite mountain. Two 25-ton security doors seal the inside offices from any type of attack. There is a self-sufficient survival system with independent water and air supplies. Sources say the move out of the mountain - billed as a cost-cutting measure - received insufficient government review, violated previous Pentagon directives, may have broken U.S. law and has left the United States less able to track potential threats and the operations center more vulnerable to attack.
