Nuclear Subs

Come in for a smooth landing as we explore the history of hangars--stark, massive structures that house and protect flight vehicles. We visit the first hangar, built on a German lake; Boeing's Delta 4 rocket hangar; Hangar Number One in Lakehurst, New Jersey, that housed all US airships built in the 1920s and '30s; and the Space Shuttle's hangar--as big as four skyscrapers! Back in Germany, Cargolifter's mammoth hangar, large enough to enclose the Superdome, signals the rebirth of an industry.
