We toss off that group of associations tagged "airship" quite glibly these days; after all, the Hindenburg disaster was at least two generations ago and might as well be black-and-white special effects. The happy Goodyear blimps and (roughly) twice-a-decade proposals for passenger or freight lighter-than-air craft are what most people think of, or possibly steampunk airship pirates.
It's easy to forget the first big impetus to turn them from flying toys into practical vehicles was pushed along by the First World War -- but BBC can give you a look over the pilot's shoulder: 1919 airship view of war-torn France. They're not talkies but the images speak 24,000 words a second.
