Hope they find the submersible soon but by now I have zero hope that they'll find them alive. Best they can achieve now is recovering the bodies, though I'd rather find the all thing squished because it means they died instantly on the spot.
Yeah I mean there are already long videos of the Titanic relict underwater and it's not like by being in that submarine you'd have a more "direct" experience than that, since you'd still be at a distance and separated by a screen/window plus tons of metal. You'd still only experience a metal...
