OK, there hasn't been a post on this thread in way too long, and tonight I saw the perfect excuse:

"The Cold Blue", a documentary about B-17s and their crews in WWII. I saw the first release at a special event tonight. Rumor has it there will be more showings in July.
I'm pretty sure every regular on this thread wants to see this. It's an immersive experience made from 15 hours of archival footage left over from the making of a famous 1943 propaganda film called "The Memphis Belle", With voiceovers by the some of the men in the film, now in their 90s. As with Peter Jackson's "They Shall Not Grow Old", this is history in the words of men who lived and made it. Beautiful, tremendously atmospheric visuals and a rather haunting score by Richard Thompson.
If you've ever wondered what a flight of B-17s looked and sounded like going to war, or what the effects of a real-world WWII bombing run looked like from the air, this will show you very vividly.
Scenes very like it will be running in ITTL "present time". Likely the launch fields will be in France rather than England, with correspondingly shorter mission durations. Fewer ships will get shot up by fighters following the Luftwaffe's heavy early losses of trained personnel. But it will still be between -40F and -60F at altitude, flak will take a hideous toll, and the devastation on the ground will be similar.
Strongly recommended.
EDIT: "The Memphis Belle" is on YouTube and it is interesting to compare the restored footage in "The Cold Blue" with the film it was originally cut into. Note that there is a different "The Memphis Belle" film from 1991 that is a fictionalization of the original filmed in Hollywood; it doesn't use any of the footage from the documentaries.
