[PSUBS-MAILIST] Thai cave kids

[Alan via Personal_Submersibles]

You have probably all heard of the Thai soccer team trapped in the cave
in Thailand for a couple of weeks now!
They are trying to train the kids to dive as one of the escape options.
One of the sections is a 20 minute dive.
What about a miniature flexible submarine.?
Have a flexible bag made of pvc with a hatch incorporated in it.
Have a small scrubber & battery & small O2 tank with one of Phils belows 
add systems on it.
The kids are weighted & enter the bag. Air is sucked out via a valve
until the unit is neutrally buoyant. 
They are hooked on to a guide rope & are pulled through the underwater
sections.
They can get out & walk through dry sections.
Thoughts?
