Didn't the Hindenburg blow up?
Yeah but it crashed after the explosion/fire.
Here it descends
Hoehling claimed the following in naming Spehl as the culprit:Spehl's girlfriend had communist beliefs and anti-Nazi connections.
The fire's origin was near the catwalk running through Gas Cell 4, which was an area of the ship generally off-limits to anyone other than Spehl and his fellow riggers.
Hoehling's claim that Chief Steward Heinrich Kubis told him the Chief Rigger Ludwig Knorr noticed damage of Cell 4 shortly before the disaster.
Rumors that the Gestapo had investigated Spehl's possible involvement in 1938.
Spehl's interest in amateur photography, making him familiar with flashbulbs that could have served as an igniter.
The discovery by representatives of the New York Police Department (NYPD) Bomb Squad of a substance that was later determined to likely be "the insoluble residue from the depolarizing element of a small, dry battery". (Hoehling postulated that a dry cell battery could have powered a flashbulb in an incendiary device.)
The discovery by Federal Bureau of Investigation (FBI) agents of a yellow substance on the valve cap of the airship between cells 4 and 5 where the fire was first reported. Although initially suspected to be sulfur, which can ignite hydrogen, it was later determined that the residue was actually from a fire extinguisher.
