Super Structures: NORAD
NORAD (North American Aerospace Defense Command) is the thigh-tech command center that monitors the skies for unidentified aircraft, missile launches, space objects, and even falling space debris. The command center is an incredible 4.5 acre compound that houses 400 military and civilian personnel in 15 buildings, containing offices, a fitness center, chapel, clinic, and barber shop - and it's all underground.
