Airship Transport

An air transport mode using a powered, steerable lighter-than-air aircraft, an airship or dirigible, to carry passengers and cargo under its own power rather than drifting with an unpowered balloon. Frenchman Henri Giffard flew the first engine-powered airship in 1852, covering 27 kilometers under steam power, and German Zeppelins later carried the mode to its commercial peak in the interwar period, when the Graf Zeppelin flew regular Frankfurt to Brazil service in as little as 68 hours with private cabins and dining rooms rivaling an ocean liner. The mode never scaled past the 1930s, however, because it demanded large ground crews and enormous purpose-built hangars, and it declined sharply after the era's high-profile airship disasters.
