I'm going to put my trust in the engineer who was overridden and fired for calling the thing a death trap before it killed five people. The thing was down-rated to 3000m and then it was used at 4000m therefore it imploded. I'd call that a management flaw more than an engineering flaw.

You're mixing things up. The hull that was downrated after inspection was a different submarine. The guy who was fired was an executive, not an engineer on the project (no idea about his background), and while he expressed concerns over safety he did not cite the use of carbon fiber as a problem (or at least it hasn't been reported that he did). Which is all to say: basing your opinions on this stuff on easily-consumed, tempting pseudoanalysis clickbait is a terrible way to figure out what went wrong. And in particular putting your ducks in this carbon fiber nonsense instead of "they probably just put a hole in the wrong place" seems poorly grounded to me.

  Just want to say, I appreciate your contributions here, from one grizzled engineer to ... well, I don't know if you're grizzled, but I can tell you're a good engineer. Good engineering isn't a popularity contest, it's a thoroughness contest.
