Earlier quoted context omitted.

you can survive over a month without food, but they must have found some water. update: they are surrounded by water which gets contaminated by their excrements. not good.

Yes, I'd like to know where they found water clean enough to drink, or a way to make it clean. Floodwater runoff is probably not the best thing to ingest…

Can't find the link, but saw a video of someone of the rescue team explaining there is drinkable mineral water streaming off the walls in the cave.

I'm pleasantly surprised to see that they've been able to survive this long without access to food and possibly clean water. I can't imagine what it would feel like to be stuck in a cave for nine days and then suddenly see two divers show up as part of the rescue effort!

A BBC article said it could be months, much less weeks. It's the beginning of the rainy season.

It's interesting, I wonder what the pros and cons are for drilling to retrieve them or send supplies. In the mine collapse situations that I'm aware of, there was already infrastructure on hand for heavy equipment and drilling.

I have to imagine that the dangers of cave diving are multiplicative - you don't get enough skill-based improvement from any given trip into/out to make repeated trips a safe option.

Assuming the divers will have to shuttle supplies to the trapped team: is there a way to make repeated dives less risky, such as stringing a guide line that divers can follow?

  Narongsak explained that the divers had fixed rope lines along the passageway and distributed oxygen tanks along their route, allowing them to advance through the exceptionally narrow passageway unencumbered by bulky equipment. Other teams worked to pump out floodwater and divert groundwater, he said.
It seems like they have something like this in place already. From what I understand the passageway is quite narrow, which would make it risky to take anything bulky through.

How does cave oxygen supply work? Would they not run out of oxygen by the time they can get out?

Also, one detail that CNN got that I didn't see in this article: it seems the cave is one kilometer underground! [1]

EDIT 1: The CNN article partially answers my first question: "Rescuers will also pump air into the cave to improve conditions."

EDIT 2: Another important bit here [2]: "It won't be anything like diving that most people recognize. It will be diving in what is effectively muddy water, possibly fast flowing, with no sense of direction," Moret said. "You can't tell what's up, down, sideways."

Me: Just drop me a gun...I'm claustrophobic and I'd rather die once.

Was there a worldwide competition for the worst place to put these kids, or what?

"None of them can swim"

Great idea to take them down into a flooded cave in rainy season. Even though now found, they will still be very lucky to get out alive. How? I think it is the case of learn to swim and dive right down there or die.

Whatever was their coach thinking?
