I'm watching the '54 film (classic) with William Holden again =, and comparing it to the book I skimmed on the 5th RCT, some stuff seems real, including living to the fullest since you could easily be dead the next day. Also I just noticed the that the admiral lost two sons in war, and his wife (right?) just sews baby's clothes (hopes of a grandchild never to come?)
When I say "living to the fullest," I mean the conduct of the two rescuers (one played by MIckey Rooney). In the book I had about the 5th RCT, they talked about R&R in Japan and how the specter of dying led you to take risks in life or something to that effect...
