I remember back in 1997, I met a veteran who showed up for a American Legion event in Ketchikan Alaska. What made him special was the fact that he was a German weapons armorer who claimed to work on Hermann Goering's plane during WW1. He was accompanied by his grandson, who supported his story. The man was very frail and did not speak much English. He was welcomed into the American Legion to partake in the festivities.
I remember there being a lot of WW1 vets in my church growing up in the '70s and '80s. Sad that they are all gone now.
