If the Hindenburg had been carrying the more expensive helium (America had embargoed it to Germany, and they had the largest supply) instead of hydrogen, and thus not caught on fire, what would have happened to zeppelin travel?
I don't think zeppelins would have lasted very long. They would have been to connected with the Third Reich, and better plane technology would have eventually rendered their role as airline ships useless. Perhaps they could have stayed on like cruise liners today?
Thoughts?
