The Handler (Kate Walsh) mentions that Joseph Spah decided not to sabotage the fuel tank in the matter of the first case she gives to Five (Aiden Gallagher). Spah was a French-born, American acrobat who survived the crash of the Hindenburg by leaping from a window and tumbling away just before the craft hit the ground. He was accused of having planted a bomb on the Hindenburg, but cleared by the FBI due to lack of evidence. German authorities never believed Spah was innocent, however.
