The Helium Control Act (1927) controlled the export of helium outside of the United States. At that time, the US had a production monopoly on the gas. A secondary factor was the cost of helium due to the general scarcity of supply.
The Hindenburg should have used helium gas instead of hydrogen gas. Helium is non-flammable, unlike hydrogen, which was a major factor contributing to the Hindenburg disaster.
Hydrogen
No, the Hindenburg was filled with hydrogen, not helium. Hydrogen is highly flammable and was a contributing factor to the 1937 Hindenburg airship disaster.
Hydrogen gas was used to inflate the Hindenburg.
Hydrogen isn't used for airships because it is highly flammable. It was one of the causes of the Hindenburg's burning.
passengers and hydrogen
The Hindenburg airship was filled with hydrogen gas, specifically about 7 million cubic feet of hydrogen. This highly flammable gas was used as a lifting agent to help the airship float.
No, the Hindenburg airship was filled with hydrogen gas, not helium. The use of hydrogen was a factor in the Hindenburg disaster, as the highly flammable gas led to the airship catching fire and crashing in 1937.
Hydrogen.
Helium was more suitable but not available in Germany before the war.
The Hindenburg was filled with the element Hydrogen, which is extremely flammable. A spark ignited the hydrogen, which caused the skin of the zeppelin to burn furiously. The hydrogen fueled the inferno.
