I feel terrible for the missing five persons on that sub, but tbh, my first thought was that there is no amount of money in the world that would get me to set foot on a 20 foot five man sub going 13,000 feet to the bottom of the ocean, much less pay $100K for the ride. I would go out of my mind in about ten minutes. On that note, my former brother in law served on nuclear sub, and told me that you had to pass a psychological exam to serve on a sub, due to being underwater for 60 days, in close quarters with a bunch of guys who would all get on each others' nerves 24/7. Hard pass for me.
