Did the Germans Think of Helium for the Hindenburg?

The airship hindenberg was almost 800 feet long, making it three times longer than a seven forty seven airplane. It its gas cells would contain almost five million cubic feet of hydrogen. In 19 27 congress passed the helium control act, which banned the exportation of helium to foreign countries without congressional approval. Germany thought it could convince congress to approve the export of helium for the project, but it couldn't so they had to fall back on using hydrogen.
