I can't figure out how to post this schematic (in this article) but it is the one I've been looking at. Is it wrong?
Thailand cave rescue: where were the boys found and how can they be rescued?
That's the schematic I have in my mind...though every time I've seen it before the left/right were reversed.
I don't think there is any way that all the boys can have already been moved to chamber three as in between the boys and chamber three is some of the hardest diving areas, from what we've heard up to now.
I am interpreting the current updates with the extra 30cm reduction in water levels to not mean that the boys can literally walk all the way out, but that there are fewer meters where they will be fully immersed, more areas where they can get their head above water, more areas that can be waded through.
We were told that between the boys and chamber three there's a 200 meter underwater section where they have to travel single file? I think it's like one of the Brit divers said about the game where you have a fox, chickens, and a sack of grain, and you have to move the chickens and the grain across a river with limits on how much you can take on each trip and you can't leave the chickens with the grain or the fox with the chickens. But in our case we've got divers going in, boys and divers coming out, and as 1 boy and his 2 attendant divers come out past certain bottleneck points, then you can send in the next divers down to the boys cave and prepare the next boy for coming out. But you don't want to end up with a bottle neck of scared boys packing those narrow passages, so they've got to be careful with the timing of achieving this back and forth movement of people. I also surmise that if the waters do start rising that they might try to reduce the time between each extraction, but just like the farmer moving the chickens and grain conundrum there will be bottlenecks where they can't go any faster.
I don't expect four boys to turn up at the entrance together. But I guess they might move 1 boy to chamber three, then send divers back for the next boy. The boy in chamber 3 gets a med check and some liquid nourishment, a break, and then does the next step (the really tight part where the o2 tank has to be removed). Then I believe there were three separate areas of 10m each fully immersed, they might have managed to get those sections reduced to head above water? And after that I *think* they might be able to carry the boys out on a stretcher...probably don't need the elite cave divers at this point and maybe two regular Seals and a medic can carry them through this section and then it should be a case of focusing on the health needs of the boy and transporting him off to hospital where he can have a full check up and get an iv in, get some rest and visit from family members.
So we might see one boy coming out every 6 hours or so. Or maybe every 12 hours two boys come out within 3 hours of each other.
That's my understanding and my thoughts...we can only wait and see.
