Your kidding me?

It shows a computer monitor screwed into the carbon fiber hull.

I’ve read other accounts that say the vehicle had a separate inner metal wall, separate from the carbon fiber hull, and the monitor mount is screwed into the inner wall, not the pressure hull.

Yes I’m being told that it is an inner carbon fiber wall not the actual carbon fiber hill. I suspect maybe there is a foam insulation between the two. That would make sense.

It was not going deeper than it had been before, so fatigue may have caused the failure, rather than stress cracks from these screws.

Navy subs which have tons of money, R&D, testing, and standards have a certain number of times they can dive before they are considered unsafe. This sub was built on a shoe string budget, one (possibly the only) engineer involved in it's development had concerns about the safety of the thing so he got fired, and it had other concerns.
