NORAD would be where our military forces are commanded from in the event of a global thermonuclear war. It\'s buries deep into the Colorado mountains and can sustain a direct hit from an ICBM if need be. When the facility was built, it was meant to be kept as a huge secret during the cold war, but as technologies advanced including nuclear warheads that were capable of piercing a few hundred feet into the ground before detonation, it didn\'t really matter. The only places that are safe from nuclear weapons are the catacombs underneath Washington DC where the president would scurry off to in the event of a nuclear attack. Rumor has it, those things are built similar to the tunnel networks in the Egyptian pyramids where the security is super tight for one thing, but actually finding the command center would take hundreds of hours if you don\'t know your way around since there are many dead ends and misleading corridors.
