I saw (I think at Facebook) earlier today the reminisces of the last living surviver of that crash ... apparently her mother threw her brother out the window, pulled back, then threw her out. I imagine the mother perished.
The US had been planning a major commercial landing field near Washington, DC at the time. After the Hindenburg, that swamp land was idle for a few decades but has now been turned into a nature preserve, a quiet haven surrounded by suburban sprawl. All the streets nearby have airline-connected names (Fairchild, Lockheed, Piper, etc).
I heard on FOX that the last survivor was 8 then, a boy whose mother tossed him out. Did not mention if mother made it.
