Ditto on the video - very enlightening.
I doubt there was another WWII bomber that could take the punishment and return home that the B-17 could. I've read several places where the 8th AF brass preferred the B-24 because it could carry a larger bomb load, but the crews all wanted to fly B-17s because the surviveability was so much better.
Asturias - perhaps, but did you catch the casualty rate of the RAF bombers vs. 8th Air Force quoted in the video?
