On a twitter site with a diagram they said 3 hours of underwater swimming! And it looked like three major flooded areas to go through. I’m guessing at least one of those would require changing a tank out - underwater??!!
I’m not trained, but went scuba diving once. It was fine - due to my ignorance no doubt! Plus - if I got into trouble all I had to do was swim up 20 feet or whatever to all the air in the world. I can’t imagine doing it for the first time in the dark, not being a swimmer, and then having to change tanks.
Dear God - give those kid’s the courage and will and calmness that they will need.
I've also been scuba diving once, lol. This rescue is definitely complicated enough, but at least there will be areas of above water swimming and three or four dry areas where they could take a break. But three hours of underwater swimming is treacherous in murky water.
But these boys are soccer players and, er, cave explorers, so they have done physically demanding things in their young lives and that is a reason for optimism. They're not a bunch of couch potatoes and computer gamers who live indoors all the time.
They are using glow sticks to light the way.
They have said the oxygen level is dangerously low where the kids are.
Why don’t they run some flexible hoses to them and pump in oxygen?
