Shanghaiceltic,

I love reading/hearing experts talk about their experiences, so please don't apologize for posting. I do have one issue to take up with you, however.

Firefighting isn't scary. It has a few dangers, but those risks can usually be managed.

But, I think the people who willingly get into a big box that has air in it and then sink beneath the surface of the sea are crazy as hell to begin with. I have never been a confined-space fan, and a submarine has to be the ultimate in confined space.

I have met two submariners in my life. They appeared normal, and I think they simulated sanity very well. In my heart, though, I know their wiring was quite different. Just thought I'd mention that to you.
