Any real-life U-boat veterans see SH3?

[CCIP]

I remember reading a dev interview where they talked about Oesten. The guy is amazing! He's well into the 10th decade of his life, but his health seems to be really good. He drives and travels all on his own, uses the PC and apparently even plays games (I think I need to bring back a quote into my signature where he talks about how a real mission of his modeled in a sim that he played was a lot harder in game than in real life), and still has very detailed memory of his war experiences. People like him are really a goldmine of human knowledge, I think - and he's definitely a testament to the U-boat men's cold toughness, too.

I was elated to see a picture just last month of the famous Reinhard Hardegen attending the commissioning of a new German sub which coincided with the 100th anniversary of the U-boat fleet. The guy also looked to be in top shape and was enjoying a drink with currently-serving officers (looking quite natural in the company)!
