It’s worth considering that BoB was atypical story that E/506th managed to be just about everywhere between D-Day and VE Day, and didn’t suffer a catastrophic level of casualties, so you could have a core cast of characters and stick with them through the entire story arc. I don't think they could have done the same with a 8th AF series without taking implausible liberties with the true story. I think I see now what they were trying to do in telling the story in three acts of three episodes apiece with different core characters and settings for each act, but with enough overlap to keep the overall narrative coherent.
I’m going to binge the whole thing through once it’s done. I’ve watched Brothers so many times by now, I figure it’s only fair.
I was listening to a podcast where one of the commentators was talking about the contrast of how the Air Force spent the war versus the Paratroopers or Marines, and observed that in some ways it might have been harder psychologically, whipsawing between several hours of sheer bloody terror with heavy casualties and then coming back to booze, big bands, and Donut Dollies.
