-Removed-Thank you, it seems probable that something fatal happened early. These are intelligent experienced people, surrounded by other intelligent people and experts and I'm sure they were advised not to undertake this excursion at this time which only should have lasted a few hours, if I understand it correctly.
@kewpie saidI will read in when I'm back, thank you.
Not the same circumstances by any means, but for me the media coverage has uncovered a long forgotten Tom Godwin "ethical dilemma" short story called The Cold Equations (1954). I'm not thinking about money or risk-taking, just being in their shoes.
@torunn saidI read that they had to sign a declaration that they would not hold the company responsible for anything untoward that happened during their trip, highlighting the serious level of risk.
These wealthy tourists must have used some of their money to consult experts before deciding to do this. A woman will soon have lost both a husband and a son, terrible time for her and the other families.
