I want to know the answer to the following question:
What caused  the Hindenburg to explode?
All the background I'm provided with is that "Pure hydrogen-oxygen flames emit ultraviolet light and with high oxygen mix are nearly invisible to the naked eye, as illustrated by the faint plume of the Space Shuttle Main Engine compared to the highly visible plume of a Space Shuttle Solid Rocket Booster.". Is that enough to answer the question?
