Sounds like the participants got more than they bargained for. The website said you can “visit one of the most famous shipwrecks” but they instead became a famous shipwreck. I wonder how many decades it’s going to take to find the wreck. Finding a 2000ft ocean liner is one thing. Finding a 20 ft submarine that’s probably completely buried in the mud is going to be a lot harder.

I just hope the hull imploded and they died instantly. Slowly dying of thirst and oxygen deprivation for a week in a dark cramped space is a hell of a way to go.
