They have another ~30 hours of air. The biggest hope is that they are not terribly deep trapped near the surface and can be located in that time.

Air is great and all, but hypothermia will get them first.

And do they have water to drink?

What is it about this type of story that is so attention grabbing? Kids trapped in cave, Plane missing in jungle, etc etc. Is there a name for this? Pragmatically speaking, this is of little consequence to most people, there are greater human tragedies going on, there are more catastrophic engineering failures happening, more egregious negligence,.. something about the unknown element of it.

In this particular story: Those guys are pioneers, they are doing something almost nobody has done before, like going deep down 4 kilometres under the surface of the ocean.

This takes guts. And people admire those that have the guts. It is primal instinct, as the people that take risks and survive usually makes the tribe or society improve.

Things that are routine today like planes flying without crashing down or reusable rockets or going to the moon were at some time extremely risky.

Wow, this is the worst possible situation, if true. They're likely to run out of breathable air long before they can be rescued. I'm hoping they make it out but, I personally would have opted for an implosion if I was in the same situation. The suffering they're enduring, if actually alive, is pretty rare. I can't imagine what is potentially going through their heads. If they are alive the 8 hour delay from Oceangate…

Isn't it just a relatively doable matter, of hooking up a wire by a robot and pulling out to the surface, assuming a suitable robot can be flown and deployed soon enough?

It's ~12,500ft (~3,800m) down on the seabed at this point, most likely. Nothing is "relatively doable" at these depths and associated conditions.

I think a lot of it is schadenfreude. A bunch of rich people pay out their ass to get in a jerryrigged submarine to look at a sunken boat and end up becoming one.

It'll be another appaling surprise if they didnt have a panel or box along a checklist, either inside the sub or next to a control panel to store and verify all those safety pins and locks.

It wouldn’t be the first time they’ve had a mundane mistake that has potential severe ramifications - like fitting a thruster backwards. Doesn’t inspire confidence. I mean - I can think of so many examples in my life where I’ve seen some safety measure Macgyvered out of existence because it was inconvenient, and familiarity breeds complacency. I’m reminded of some really gnarly ski lift accidents where emergency brak…

The Risks Digest. Highly recommended.

Endless food for thought.

They are outliers.

Most tragedies the people are dead, outcome is known.

These situations usually have these things in common:

1. Very unusual situation

2. Race against the clock

3. Remote location

4. Extreme measures needed for rescue that may have never been done

5. May still die even if found

Just add a line. It's only 2 miles.

Apparently having a tether is not a bad option. So what’s the reason they didn’t go for it?

Possibly because they were closing in a wreck and a tether can get snagged

And I guess they were doing very close flyby, visibility down there is real bad.

I have a dumb idea; how hard is it to add a location tracker to these kind of subs? Does the high pressure make this incredibly hard to add?

Its not the pressure, but the fact water blocks radio waves. Submarines can’t get GPS signals or transmit their location. Submarines have to rely on other means such as IMUs to track their own location.

What about a signal flare that floats to the surface?
