Nothing to see here. Darwin did his work again. C'est la vie. Princeton should be embarrassed for graduating this guy.
My wife and MIL have been fucking glued to the tube about this story; but I find it boring. 5 dummies jump into a metal tube and descend well over two miles deep to peek through a small shitty window at something they can better see from the comfort of their desk chairs. One dummy brought his 19-year old dummy son, thereby risking his boy's life all so they could drop the experience of "being there" at cocktail parties. Lolz.
This, like mountain climbing, is an area I don't want to regulate. Regulation costs me and you money because we have to pay the regulators. Let people do what they want to do as long as their fuck-ups are self-contained and don't affect others. I don't want large search & rescue and I don't want to pay regulators. Let them implode. IDC.
