It's a trailer. (and very well said Hiro) And this is a film, not a flight sim!
hehe
Hollywood and other Major Film Studios (LucasFilm included) makes movies to cater towards the general audience.
Using the statistics they gather, (numerous is an understatement) Each director has a formula whenever they try to create a movie. As much as we would like to think otherwise, totally factual based history can be rather dry and bland. Drama is needed because conversations, even confrontations can be ...for lack of a better word, boring. (Though now we have reality based TV shows to show each and every one of us how to be a 'drama queen', lol!)
The advantage Lucasfilm has is that it is a self-sufficient entity seperate from Hollywood so that his studio has total say in the product. He did this after his incredible success with 'SW' so that he would never have to depend on backers and Studios when creating his sequels/prequels. And as an Artist, he is constantly refining each piece with each re-lease.
How much of a full hand does he have in "Red Tails"? I'm not too sure. Unlike the 'SW' series, he's probably playing more of a supervising role and delegating some freedom to those he assigned to make the film. Not being 'his baby', he is very aware of how the movie needs to be in order to have general acceptance with the public. So be aware that when things don't look correct, out of perpective, or too close together, etc., there is a specific reason for it being that way as well.
Film is the art of storytelling condensed into a 2 hour (or less) movie.
...and hellyeah! I'm looking forward to seeing this one!!
(Have you seen the theatrical release poster??!!)

BTW, it's just a trailer. Still 4 1/2 months till it's release, and a lot can happen behind those closed doors in Skywalker Ranch!
