Interesting. And a lesson to be
learned.
GK made diving history, had extensive training and
experience in fleet boats, and designed, built and operated his own line of
subs. And some of this valuable insight couldn't be
transferred over to a psub.
A little like thousand hour pilots asuming they
know how to fly ultralights. Well, yeah, in a sense they do - until they
get in one.
Once again, a lesson to the rest of us. Sometimes
humility can be awfully hard to come by.

Not complicated. A bag over the head, more or less. It gives you a
captured air bubble at whatever pressure you start from, provides
lift as you rise, equalizes constantly and lets you sip a little air on
the way. And just as a piece of trivia, George Kittredge tested the first
American escape gear, at depth, in the open ocean, from a submarine, just
after World War II.
I was thinking about George's snorkel and remembered that he didn't hold
with pressurized oxygen and the like. His idea was to surface every hour or so
and ventilate the compartment, which the snorkel helped to do. I asked him
back in the early 70s what he'd do if surfacing wasn't convenient, like
maybe you were tangled on the bottom or something, and he looked
thoughtful about it. Pretty quick afterwards they designed and fabbed the
K-600 for some Norwegians and included a life support system. His personal
K-350 had an O2 storage and baralyme scrubber, as well.

Vance,
I do not yet fully understand the mechanism and physiology of the
"hood" system. Something to look at more closely down the road.

Frank and Joe,
The Navy trains blow and go with hoods, not bail-out bottles.

Frank,
Actually, I have thought about precisely this very issue in an effort
to train my family members under "wet" conditions.
The goal would be to train them how to "feel" for escape equipment,
maneuver within the hull, and escape through the hatch. Having practiced
this under "wet" conditions would have the same confidence building / panic
reducing effect as removal and donning SCUBA underwater.
What I am considering, is a light "open ended" mockup
of the hull and tower, for my home swimming pool. Same dimensions, but
a light and sturdy enough material to be practical, not damage the
pool, and not move around too much.

I wonder if there's a way to practice an escape under "wet"
conditions (without flooding your sub.) As a diver, I have practiced
several emergency techniques for different scenarios. I always assumed the
psubs would carry scuba gear for all passengers, mask, tank, and belt, as
a minimum. The small emergency bottles divers carry on cave/wreck dives
are not sufficient. I've never owned one because I always thought they
give a false sense of security. There's not much air in those things. Much
better to be prepared for emergencies with proper training, planning, and
practice. On dangerous dives, extra full size tanks with regulators,
stationed within reach, is the best method. Naturally then, you'd want to
have the same thing in the sub with you.
As for the accident, a blown window will result in instant
pressurization, and at 200 feet, I'm surprised anyone survived. A
very unfortunate accident, and a good lesson to us all. Frank
