Not true. The Hindenberg used hydrogen which was initially blamed for the disaster. Subsequent investigations have advanced the possibility that the treatment applied to the skin of the dirigible was the true cause.
In an effort to keep the Nazis from using the Hindenburg for military proposes the United States Congress passed the Helium Control Act. This Act made it impossible for the Zeppelin Company to obtain Helium because the United States has the only natural deposits of Helium. This upset Dr. Eckert who got along well the United States government and was openly critical of the Nazi government. There was nothing for him to do; therefore on March 4, 1936 the Hindenburg, inflated with the volatile gas, hydrogen, made its maiden voyage.
