FWIW, Jon Stewart interviewed George Lucas about a week ago on The Daily Show. GL said he spent a lot of time interviewing the remaining Tuskegee airmen, and when they saw the final print, according to him, a lot of them came up to him with tears in their eyes, "You got it right"; including a few of the bomber pilots.
Now, I know how popular GL is on this forum, and most of you will yell that he's just trying to line his own pockets in that interview. Shoot, like Srvy said above, I just like watching WWII aircraft battles and this looked like a fun "popcorn" movie that I'd enjoy in the theater... :|
