propulsion unit

something like this. teaching them to dive and leaving them there for months does not sound great. you just don't know how cave will fill. they have pumped a huge amount of water out of the entrance to the cave so the journey will be shortened. they can walk out part of it. why would the seals not have something like a propulsion unit in the places where the tunnels were not totally filled with water? you might break a few but they have roped off the route and put all sorts of oxygen tanks in place. each boy would have two navy seals. i would expect some would have to be tranquilized somehow and towed out. some government official i guess said the group would not be split up..but has backtracked. never make announcements like that. save whom you can as quickly as you can. it might be the smallest or it might be the strongest.
