It was Sabaton who introduced me to the story of Franz Stigler and Charlie Brown with their song “No Bullets Fly” (Animated story video https://www.youtube.com/watch?v=dslO-3GgenY).
I was exposed to stories about the mighty B17 thanks to MicroProse with their title B-17 Flying Fortress (1992) early so my interest was easily triggered and I was delighted to find out that there is a book about this war story, that apparently really happened.
Got some more info from the Sabaton History channel (https://www.youtube.com/watch?v=LSU7HedRVGY) and purchased the book A Higher Call: An Incredible True Story of Combat and Chivalry.
The story and the aftermath, that are still happening today, really touched me. There is also the fact to read about this fascinating story written by the American Adam Mankos, who in the beginning didn’t care about the point of view of an former enemy, a German, at all, bringing this event after much research to paper: https://adammakos.com/a-higher-call-book.html
Read it. Or listen to the audio book. This may surprise you.
