Super interesting. Can't comprehend how the sailor lived in that claustrophobia-inducing space for over 48 hours. Human spirit in these extreme situations is really something.
I think that sailor is unique more for being rescued than for being in that position in the first place. I don't think "trapped in an air bubble in a sunken ship" is all that rare of an occurrence. Look at the K-141 Kursk disaster for example - 23 men survived the initial explosion, and spent the next several days in a compartment before succumbing to fire.
