Here is a fascinating story about German zeppelins, focusing on their hangar in Brazil:
It's unfortunate they fell under the shadow of the Nazis, because Nazism had little to do with the zeppelin phenomenon. It's also unfortunate that people focus on the fate of the Hindenburg, since other airships like the Graf Zeppelin had long history of safe flight.
No one has ever mastered airships like the Germans did. I doubt we'll ever see their like again.
