I know, I've seen the video before, but I never took that comment to literally mean that every single man onboard O-19 had been onboard O-19 since they'd left Europe in 1939.

She went through 5 commanding officers during that time, so why other crew wouldn't change either is beyond me. The commander at the time had only assumed command the previous December. She'd even been back to European waters in 1944. Of course none of the men had seem home - Holland was occupied by the Germans. But it's not like the crew had not changed, nor that the crew had even been in the east Indies the whole time. And they'd certainly not spent 5 whole years never stepping off the boat.
