I will say that I have seen a lot of war movies in my day, some of them good, some of them bad, but I will have to say that very few war movies hit the note for historical or technical accuracy.
Having watched Flying Leathernecks with Manon (Tornade) I can tell you that she was not particularly interested in the historical accuracy of the film, but merely its entertainment value. I don't know for sure if she is terribly aware or even cares about when Hellcats came into service, she just likes them.

As an ex military man and something of an enthusiast, I can often point to technical mistakes and inaccuracies in just about every movie made. In most cases though, the general movie goer never notices. How many of the general populace would know a Tiger tank from an M47 ? Yet it was the M47 that starred in the Battle of the Bulge film and we all know that it was the pivotal battle for the fuel dump that caused the defeat of the German army.
Does anyone really care that it was a crack regiment of Italian commandoes who very nearly turned the tide at El Alamein. Are we really supposed to believe that the American army won World War One, succeeding where the combined armies of Britain, France and Canada had failed.
I think the term is "Artistic License" You and I might call willful ignorance. In the end though, it is the flashes and the big bangs that make the movie exciting and not the fiddly details about the wrong colour on the collar flashing of the enemy soldier's uniform.

Sit back, turn up the volume and pass the popcorn

Dam Busters...Damn good movie
