one. underneath each diver. so each diver had a boy underneath him as they submerged into the water. the boys wearing full scuba masks and then after about a mile, they were able to reach what s called chamber three which is dry, and from there, they could walk, but all told from the place they were to the mouth of the cave, it s about two miles, and remember, these are boys who were weakened, who didn t have anything to eat or virtually nothing we understand for nine days. so an extraordinary operation. they held onto guidelines. they had oxygen lines along the way. there were divers all ago tlong way, but remember, david, this is a potential death trap because a few days ago, a very experienced highly trained thai diver collapsed and died due to lack of air. so let s not underestimate this operation. it is potentially deadly, but it was extraordinary. it was launched in very dramatic
took certainly more than one of them out. we don t know the composition of the groups. we don t know if the youngest is gone first or the strongest. they haven t given us that detail. they will take them out in groups. they will go along guide rope lines. they will be with a diver at all times. there s a three-mile oxygen line from the cave right to the exit point. but, this is a very, very dangerous route. remember, a highly experienced, highly trained thai diver collapsed and died in this water, in the cavern. if it can happen to him, it can happen to the boys. it is agonizing for the parents. the rescue operator said if we don t start the rescue on the best day, we may lose this window. no day is better than this. we have to act now. the reason they have to act now,
mission. one of the workers, one of the rescuers who was trying to prepare the cave. what do we know about him? what do we know about the man who died? reporter: this was a former thai navy s.e.a.l., a thai diver, a 38-year-old tri-athlete who lost his life bringing in some of those oxygen containers i was talking about, he apparently ran out of air and died himself. that s why we re talking about how unbelieve believe dangerous this rescue mission is. this professional diver, someone who was in the thai navy, he was a navy s.e.a.l. actually lost his life in the same passage ways that these four boys just circumnavigated. that is unbelievable. when we are talking about this rescue mission at least so far being a success, brian, 15 hours ago i was saying that was far from guaranteed. this is miraculous that four boys are now safely inside that
