The divers have rigged guide ropes through the passages of murky water and placed air tanks along the route. There is only one way out. And there is no hurry. The trapped can be supplied with all the food, medicine, lighting and communications they might need. Their only need that cannot be supplied from the world outside is mental fortitude.
The expert rescue divers now with them will be doing their utmost to make the boys relaxed at the idea of a long journey under water. If this is a typical bunch of early teens, some will be keen to have a go, others definitely not. Those not confident in water will be battling terror. The keen ones will probably be given plenty of practice, because they will need it and because watching them should lesson the fears of the rest.
They were a team when they went into the cave system and are probably a closer team now. For nearly 10 days they huddled together in darkness and silence deep underground. They would have lost track of time, sleeping fitfully, drinking water dripping from the roof of the cavern, growing more hungry and worrying they might not get out.
Compared to that worry, the ordeal they now face must seem manageable. For their families outside too, the relief that their sons have been found alive appears to eclipse any worry about how the boys will get out. Only the rescuers know how hard and risky it will be to see that the boys do not panic when they find themselves squeezing through narrow confines where the water flow is overwhelming.
Will they all come through? They have done so well together so far, they can surely give their adventure a happy ending.
