I think what I find fascinating is how much the frequent airplane crashes of the 20s and 30s (and hell the 40s and 50s) have just been forgotten. Perhaps because they tended to end up being in conditions with less publicity.
Fog in New York caused plane crashes into both the Empire State Building and 40 Wall Street in 1945/46. I wonder if it would have been possible for something similar in the 30s to act as a Hindenburg-like effect on planes. Though I doubt you'd have anything like the memorable footage.
