Re: Fw: Re: [PSUBS-MAILIST] Scuttle valve

I don't understand how that removes the need for a scuttle valve.
If you sub is caught on something under the water  and can't be lifted, all the
divers in the world won't be able to open the hatch because of the external
pressure.

How do you plan on getting out?  I may have missed something key
point here, so feel free to correct me.

Thanks,
  Ian.

Just like scuba diving, would you go out sub diving all by your self? No.
This is where planning your dive comes in to play. This is where having
several days of life support on board, comes into play. This is where
communications comes into play. You are still chewing on your arm. I can
understand leaving the sub if your building a sub to Carsten's proportions.
