Interesting..this brought up a memory and a discussion with my elderly ma last night.
As a child..she distinctly remembers one day in her village along the coast - she saw something coming over a far hill at low altitude...it soon began to literally fill the sky over the town...the whole village turned out to stare..
It was the Hindenburg.

.huge and shiny with big swastikas and all..she said it was so low you could almost see the folks in the gondola..it followed the Nova Scotia coast down to NY as part of the route.
Scared the heck out of them and her. Up to that point they had never even a plane before.
