Airship Hangars
Airship hangar (also referred to as "airship sheds") are generally larger than conventional aircraft hangars, particularly in terms of height. Most early airships used hydrogen gas to provide them with sufficient buoyancy for flight, so their hangars had to provide protection from stray sparks in order to prevent the flammable gas from exploding. Hangars that held multiple craft of this type were at risk from chain-reaction explosions. For this reason, most hangars for hydrogen-based airships were sized to house only one or two such craft.
During the "Golden Age" of airship travel (starting in 1900), mooring masts and sheds were constructed to build and house airships. The British government built a shed in Karachi for the R101, the Brazilian government built one in Rio de Janeiro pt:Hangar do Zeppelin for the German Zeppelins, and the US government built Moffett Field, Akron, Ohio, and Lakehurst Naval Air Station, Lakehurst, NJ
