I happened to surface in a small air pocket and I didn’t know if I was upside-down or standing on the walls or what. I made a dive into the pilothouse and I could see some light—it could have been a window or a porthole, I don’t know—and when I got back up into the wheelhouse there was no more air. It was all gone. I was thinking, “This is it. Just take a mouthful of water and it’s over.”
