That Hindenburg fire is still subject to debate. Several plausible theories & no way (today) to prove which one actually happened.
Hydrogen burns with a nearly invisible flame (it radiates in UV, not visible). So the luminous fireball in Lakehurst must have been fueled with other stuff along with the H2.
The cotton fabric painted with cellulose-acetate-butyrate with some aluminum mixed in is plenty flammable already. Could have been a nice luminous fire even if the Hindenburg were filled with He.
This was the general time period when photographic film was also moving away from celluloid (nitrocellulose with camphor) because of flammability. Today we live in a world where it's commonly accepted that everything is flame retardant. Not so much in the 1930s.
