> I don't see how the vacuum ever wins.

3 ways.

- Vacuums aren't combustible.

- Vacuums can be created without sourcing a gas.

- Vacuums allow you adjust buoyancy without requiring you to carry extra gases.

The major downside of a vacuum is finding something ridged enough, light enough, and cheap enough to maintain a vacuum.

Helium isn't combustible either.

It's also finite and much more expensive.

"vacuums aren't combustible" oh I love it idk what you did here, but the assumption of hydrogen still being used is awesome. reminds me of a great Archer episode.

Its a little disingenuous to imply that a vacuum is safer than Hydrogen just because it doesn't combust. Have it spring a leak near the passenger cabin and watch what happens: https://www.youtube.com/watch?v=cPoVuFtWs_Y&t=7s
