Great 90 minute film, released during WWII recounting a specific operation against Nazi fighter production in what looks like late 1943. (They may have said and I missed it)
Great graphics, some cheesy "oh, hey, you can barely pull the trigger" bandiage, and a real sense of how harrowing the whole enterprise was. 10% was a good casualty figure on any raid. Over the entire war the strategic bombing casualties were 50%.
Note that at this point it was still the "Army Air Force" and not a separate branch of the service.
