Correction - I talked to my father, who was also in WWII, and he told me the guy I mentioned before was not a ball turret gunner but rather a tailgunner in a B-29. He had 37 missions to his credit.

As for the PC stuff in Ken Burns' documentary, it can't be as bad as the way they have ruined the Liberty Bell display in Philadelphia. About 50% of the display makes damn sure we all know about slavery.
