A rather fascinating documentary, interspersing real footage (the crash but also a passenger shot footage onboard, that somehow miraculously survived the crash) with period-accurate recreations, so well done that it was sometimes impossible to tell which was which.
When the airship blew up many people assumed it was sabotage, because this was the first U.S. landing of the pride of the Nazi dirigible fleet. There had been threatening letters. There were nut jobs who claimed responsibility.
But as we all know now it was simple static electricity, although by all known science it should have exploded the minute the mooring ropes were dropped to the ground, not four minutes later.
I was surprised at how many passengers survived the crash - 62.
