I’m surprised you didn’t mention the similarities between the big attack in this movie and “633 Squadron”. Both flying up a twisty valley, against ground defenses, fighters poised above, having to drop the ordnance on a small target, etc.
For THAT matter, the same plotline was used as the climax in the original “Star Wars.” Do a Goggle search along the lines of “video 633 squadron star wars”. It’ll bring up a video where they take the video of the attack sequence from 633 squadron, with the audio soundtrack from Star Wars. Amazing how the two match up…
