The men and women of the USS Nimitz live beneath the runway of a major airport. They sleep on the roof of a nuclear power plant. It's a perilous environment. Their only bulwark against danger and chaos is to bond with their units on board the ship. The "Shooters," who launch the jets, have a "Circle of Trust"; the Ordies (ordnance personnel) pride themselves on being a "mafia"; the F-18 squadrons - the Black Aces, the Hoboes and the Marine Red Devils - are tight fraternities.
