The Trieste was sort of an underwater Hindenburg, minus the fireball. The Hindenburg's structure was heavier than air and the bags full of hydrogen gas was lighter than air.

I read about the Trieste today. Twice as big a vessel with room for only 2 people. And went much deeper. Interesting stuff. I’m surprised those lost this week were so accomplished yet got into this very questionable vessel.
