That's scary shit molson.
I can't even fathom (no pun intended) how those expeditions don't have a million cameras inside and out with people on the boat constantly monitoring them! I was confused at the part where it said it was a tourist submarine yet there were five CREW members. So what you're saying is they just call the tourists "Crew". It's good that they are actually training them before they go. But that makes it make sense they called them that when it's not really true. That billionaire was a tourist. Other than that I wonder how many others were.
