The irony of ignoring safety...dying in an unsafe sub while attempting to visit a shipwreck which notoriously occured after ignoring ice warnings and had insufficient safety measures. Do we not learn?
This is the best case scenario though. Those folks were quite literally atomized before their brains could even send a signal that it was happening. Zero pain, just an instant lights out.
I feel poorly for the 19 year old kid. His sister has said that he didn't want to be there, was terrified, and was only there to please his father after someone else backed out and a seat opened.
The owner of the company is on record saying that the regulations regarding these subs are "stifling innovation" or some such. Regulations are written in blood. He tried to get away with it, and paid with his life and four others who trusted him. He was warned, repeatedly. I have little sympathy for him, but I do for the other four.
