Litchfield had the vision. He built the Airdock because he wanted to construct a new generation of huge, state-of-the-art helium-filled rigid American airships for long-distance commercial passenger flights, and to position Goodyear as the world's leading manufacturer of passenger-carrying airships. Rigid airships are given their shape by the complex metal framework needed to support a huge envelope filled with enough hydrogen or helium to lift a sizeable number of passengers, or cargo, for days at a time. The contracts he signed with the US Navy to build the USS Akron and USS Macon, the world’s first flying aircraft carriers and two of the largest aircraft ever flown, would subsidise the research and development needed for these passenger craft.
