I found another interesting photo in an aviation forum that looked like a good candidate for colorizing, in this case it was the crew of the "Hell's Angel's" B-17 adding the numbers for their latest bombing mission. (Which looks to be just shy of 40 missions.)
You can read more about this B-17 at: https://bit.ly/3hvp4Mg.
By the way, for those who've never seen it before, Jimmy Stewart helped create an Air Force Training/Recruitment film in 1942, wherein he describes the duties and responsibilities of a B-17 crew. (Although if you know your B-17 history, you can tell that the video is of a very early version of the aircraft, and not the version that saw most of the combat during the war. Can anyone else point out the most-important differences?)
PS - Despite having created this film, during the war Jimmy Stewart flew B-24s.
