Highly innovative! Instead of their sudden death being a complete surprise, they may have had a few awful moments of warning.

The engineer who worked on it said it would provide only milliseconds of warning before the hull collapsed. He was promptly fired.

Source? (the story does sound plausible, but having a source would be helpful)

Yeah, mechanical failure was not a major problem with subs...until someone started gluing dissimilar materials together to make one!

It also sounded to me like dodging the question.

Giving them the benefit of the doubt, they're saying the biggest problem with submersibles is operator error. Of course it is, when the classing system effectively eliminates the majority of mechanical failures. That doesn't mean the classing system is failing, on the contrary, it means its working.

Reminds me of some code that I've written which got passed off to other teams who ripped it out because all they saw was the complexity and they didn't recognize what issues it was preventing (Chesterton's Fence).

Could that be because the vast majority of mechanical designs go through processes designed to validate them and catch flaws?

They also use SpaceX as an example. SpaceX ran a large number of unmanned launches to prove out the design before putting people on board. Several of those ended in loss of the vehicle and the data from that was used to refine.

Read that also, can't remember where.

Wouldn't they have communicated that back if they had? There wasn't even an "Uh-oh", as far as we know.

It takes longer than a few milliseconds to say "Uh-oh", probably.
