"I think all of your ideas are marvelous!"
Joey,
Thanks for the complement but....geez, ....you need to speak to my wife! :) "Mad Scientist" is the latest term thrown my way!
If the fellow you mentioned is practicing water landing egress from light aircraft, refer him to the recommended procedure of opening the door prior to impact, as the forces are likely to warp the fuselage and jam the door shut.
A prior post regarding operating a psub beneath overhangs (manmade or otherwise) reminded me of that very same aircraft analogy. Aside from unseen entanglements, an uncontrolled ascent, (accidental weight release), or loss of buoyancy control for any reason, could cause unimaginable trouble.
When you look at Alvin's rather simple operational restrictions, you begin to see why,... and I begin to see my own operational restrictions.

The #1 reference to the "Pilot in Command"...is very familiar territory.

I think all of your ideas are marvelous!
I have heard of a fellow out by where I live who brought a large out-of-ground pool, and mounted a cross-section of an airplane on a hoist system. He would then shut the small section up, and it would be waterproof. His wife [or son, I don not know for sure] would be operating the hoist system, and would drop him or an occupant down there. Either another diver is in the pool, or manually opened, a small nozzle is opened to allow for flooding. You then have to practice putting on an oxygen system and tanks, and manually fill the mockup with water via a full until it is completely full of water, which makes it easier to open the hatch and simply swim out.
No pictures as of yet, my apologies. I was thinking that [although] that system is used for a small aircraft mockup, the same principle can be applied to a submarine mockup, etc.

Joe...Just what I was thinking. Great idea. Maybe made of fiberglass, or even rigid plastic sheet. Something to enclose a space but maybe you could "punch" through if someone panicked. Practice is a good thing. Frank D.
