I am fully willing to admit half the reason it's so popular on the news is the novelty of it. A submarine goes missing, possibly sunk, near the Titanic? The truth is the accidents iwth immigrants and migrants happen so often that most of the media doesn't really care about it so much any more. But it used to, I remember seeing stuff about bodies washing up on the shores of Italy. When it was novel is was more popular and 'sold' well so it was reported on. i guarantee you if subs went missing anywhere near as often in the future you would not see as much about it. That's just how the media works these days, it's unfortunate.
Billionaires or not I don't envy them and if they can be saved I hope they will be. Especially the young guy there with his father.
