I saw the inside of a fuel tank in AlphaPhoenix's latest video (wait I just realized he never shows it here, maybe he edited it out?) and it's really cool how they make the surface rigid with as little structural support as possible with thin, vertical struts that run across the back of the surface of the tank.
I found a YouTube link in your comment. Here are links to the same video on alternative frontends that protect your privacy:
