- crikli 11y agoYup. My dad was a RAD/MAD operator on a P3 during the Vietnam War. One of my indelible memories from childhood is him explaining how it worked and a story about seeing a Soviet sub on the surface. Of course as a kid having watched Das Boot I'm expecting there to be guys scrambling to the conning tower, dive dive dive, depth charges, etc. He's like "nah, the skipper just circled the thing and we waved at each other." Seeing this story on HN makes me wish I could hear the story again but he passed of cancer a few years back.
