Interestingly, I walked through the same plane when it was on display in Salina, KS, with several other WWII aircraft. My half brother was a B-17 co-pilot in WWII and his plane was shot down over Nazi held territory in Holland. He and the wounded crew all survived after being smuggled back to the Allied side with assistance from the underground network. The pilot's son has written a document based on his father's recollection of the events, it is amazing. I have a deep appreciation for the men who manned these aircraft as hydraulic and electrical systems were very primitive back then. They literally flew these planes with cables and pulleys. These men encountered staggering losses among their ranks when at one time the odds were you would be shot down within six missions. I'll always remember the sound of that B-17 on a flyover, those vintage piston engines churned horsepower in a class by themselves.
