Question

How would the results of the spark have been different if the Hindenburg had been filled with helium?

Answer 1

Answer:

The airship was designed to be filled with helium gas but because of U.S. export restriction on helium, it was filled with hydrogen. Hydrogen is extremely flammable, and the official cause of the fire was due to a "discharge of atmospheric electricity" near a gas leak on the ship's surface, according to History.com
