“The rest of the industry doesn’t do what Srockton Rush did.”
Working in the aviation maintenance field for 36 years, because of the obvious concern for air crew safety, we had a saying....the Russian proverb made famous by former US President Ronald Reagan “trust but verify”.
Since crew safety IMO is just as critical when going beneath the waves, especially in the light of what has now happened, I’ll stick with my belief that the whole industry needs indepth critical oversight and review.
The other crews, being experienced people, would not, and do not, use ships that aren’t tested, and they follow regulations, because of precisely what happened here with a company that didn’t use experienced people, fired the one experienced person that raised serious concerns, and built a design that didn’t even match his original design specs.
