Any decent military is going have crash retrieval teams. It’s called CSAR - combat search and rescue. If a Russian or Chinese jet crashes somewhere neutral, we are going to race to get there. If it’s our own F-35, we will get there even faster and probably fight anyone who tries to get there first. I imagine you would do this for any interesting craft that crashes.
Linux is Linux. The differences largely come down to packaging and release cadence. You never really have upgrade difficulties with Arch due to the rolling release model as long as you are updating pretty regularly. On other distros, it’s not uncommon to deal with release upgrades that can be a little more involved. The other advantage to Arch is the repository and AUR. You can install just about anything with one command/click.
Personally, I think Arch is the easiest distro to use once it’s installed. I was a Debian user before Arch for mostly the same reason - it’s so easy to install software because the repository is huge. Being on Mint, you have access to a lot. Just imagine having access to even more but needing a little more knowledge to get started and that’s Arch.
