Somewhat related. I went to the Oregon Museum of Science and Industry (OMSI) in Portland last fall and did a tour of their submarine, the USS Blueback. Our tour guide was a retired Cold War-era submariner and he was fantastic. He gave us tons and tons of details about what life and working on an active sub was actually like. It felt like being there, and you could tell he delighted in being able to share his past with people.
