This reminds me of the Spitfire 944 short film that won a bunch of awards about 7 or 8 years ago. This is even better though, great interviews with the remaining vets, especially the last/credits scenes, he was great.
The sequences showing the LW fighters and gunners has the very best a2a footage from the B17 perspective I've seen, seeing lines of tracers going out in various ways, and even hits on LW fighters. Fantastic, worth the watch just to see this IMO.
