Red Tails:
To give you a flavour, I liked the bit where they sank a German destroyer, which obligingly exploded after a couple of 0.5in bursts, on the way home from an escort mission.
Well, that's in Tuskegee Airman as well.
That film is very, very good.
Historically accurate, politically incorrect and chock full of action (no CGI there)
Highly recommended.
