Outside the hospital where the four boys are now being treated. let's go first to jonathan miller. this was an extraordinary rescue. there's still a long way to go. so how do they pull this off? >> reporter: joe, they had about 90 rescue workers in total down in that incredibly labyrinth and cavern system. only 13 of them were involved with the actual rescue of pulling the boys out. they were the trained cave divers. each boy, each of the four boys who have come out had a diver, one ahead of them and one behind. the boy in the middle held on to a rope tethered to the front diver, who also held...

Daring and risky cave rescue of these 12 boys and their coach, stuck in this cavern system. in order to do this, they will have to dive some of these boys out and it's very, very risky. there could be some last-minute hitches and delays. the boys have to get medical checks before they'll be allowed to even attempt this. but as far as we can ascertain from officials here on the ground, they're pretty much in a position to give a green light on this very risky operation. >> so, what's the weather like, and how long is it expected to rain? >> reporter: well, about an hour or two ago, we had an ab...

Into the cave roof and extra extracting them that way, that could be preferable to having them come out the way they came in, because that would involve them diving, learning first to use scuba gear, then diving with the cave divers helping them through half a mile of submerged narrow passageways. it is all together, i think, around three -- four kilometers that they'd have to make their way out. that's really, really risky. but the risks also involve leaving them in there because, within a few days, that deluge of the monsoon will come down again. that cavern system will be submerged for the ...

Race against time. >> so jonathan, they brought four out today. if they use the same number of people, do we presume that when they go back, they're going to bring four more out and then have another hiatus or try to bring out all eight at once? >> reporter: well, you know, things change. the situation is fluid. i think the plans may change because of this extremely heavy rain. it's been raining for hours here now. it's a huge catchment area. as the water pours into that, it's funneled down into that cavern system. goodness knows how quickly that water table can rise. the pumps find it hard to...

Ago, is that there has been -- the oxygen tanks that had been prepositioned down throughout the cavern system needed to be replaced. they didn't just keep on bringing boys out until they had got more oxygen tanks inside. he said there would be a 10 to 20-hour hiatus. that's already five hours old, that information. we can expect the next batch of boys, we think they're going to come out in three batches of three, the next lot, to start again in probably 12 hours' time or so. we know that the operation today went remarkably successfully. normally it takes these incredibly experienced cave diver...
