Hi Alan. Have you been drinking a lot of wine? How many bags have you saved
up?
Just kidding.......as a scuba diver, I can tell you that won't work. If we
are escaping from a sub, the last thing we need is a bag full of air to deal
with. If we get pressurized at depth, make it out the hatch, and head for
the surface, we probably won't even need scuba tanks. The air in your lungs
expands as you rise, quite a lot.
The danger of rupturing your lungs is very real, so scuba training is
essential.
The 40 cu.ft. scuba bottles used for escape are mostly for breathing while
the sub floods, and climbing out through the hatch. If it's really deep,
maybe a short de-compression stop near the surface if we're still conscious, but
mostly we will be shooting to the surface with whatever floatation device we
have, and blowing out air as it expands in our lungs. Frank
