oh wow, the Titan Sub accident investigation has a bunch of new documents on the US Coast Guard site: https://www.news.uscg.mil/News-by-Region/Headquarters/Titan-Submersible/
Damn it is depressing that these fucking idiots got away with crap like this. I've spent a lot of time in aviation. You see occasional stupid crap where owners or builders or the occasional A&P (licensed technician) does something wrong/sloppy/stupid but there are many ways those problems get caught and great mentoring say in the EAA.
