If I were so obscenely rich I could drop half a million to take a family member on some risky trip to, say, the bottom of the ocean, I'd probably consider dropping a few thousand extra to hire someone to research whether the guy running the trip was a total clown who ignored blatant engineering and safety issues https://newrepublic.com/post/173802/missing-titanic-sub-faced-lawsuit-depths-safely-travel-oceangate

@AbandonedAmerica Well, to quote every DSV designer I've heard - the thing was designed badly. The bow viewport was only rated for 1300 meters coz it was out-of-spec and, frankly, negligent homicide charges should be considered.
@Gojira1000 that's my point - you'd think any engineer who gave this thing even a cursory glance would laugh at the idea of traveling to the bottom of the ocean in it
