Original color footage of World War II aircraft including B-17, P-51, Spitfire IX MJ730 and P-47. The B17 looks new and has no squadron identification. Those spits with the HT squadron markings are from the 154 RAF Squadron, and they were loaded with 90 gal slipper tanks.
On top of that, it was done in color by the film crew of William Wyler (Memphis Belle director). It was filmed in Corsica in 1944.
