ITs got allllll kinds of fighters and bombers and from what I hear you can even jump in a tank or other vehicle. Its supposed to be pretty in-depth. I just got it so I havent been able to explore it fully yet.

Get version 2.77 toward the bottom of the page. I heard the one (warbirds 3) at the top had some problems. I dont know that for fact. If you have a cable modem try them both out since it wont take that long to download both. (Warbirds 3 is 113 meg)
