(an alternative take on "aviation is really remarkably safe" by lintamande, which should be read before reading this)

Flying in an airplane is approximately the most dangerous thing that normal people do on a routine basis.  (Traveling to the Moon or Planet Four is more dangerous, but most people don't do that once, let alone routinely.)  It's not so much that the machinery has a higher chance of breaking compared to your lawnmower, but that, if something does go wrong, your brain has a higher chance of being smashed, roasted, or sinking to the bottom of the sea.  In which case you true-die instead of getting frozen.

Worse than that, if something goes sufficiently wrong, an airplane can truekill a non-customer, somebody who didn't decide to risk their own true life in any way.  It could crash into a skyscraper.

Aviation is accordingly one of very few activities on dath ilan that is genuinely stringently regulated in a way that's hard to individually opt out of.
