The British sought to build an "Empire in the Air," by starting their own fleet. The Germans rose from the ashes of World War I with the most successful airship ever built: the LZ-127, Graf Zepplin. The Americans began by trying to purchase airships overseas. Two proved disastrous. Building a new industry, the US Navy built a copy of a Zepplin and christened her, USS Shenandoah, the ZR-1. This documentary covers the history of US airships.
