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… https://beko.famkos.net/x/1byC
