This game has a lot of potential. Unfortunately, I can't get past the Training Flight. I successfully complete it, but I only get one mission in the Campaign section. There are suppose to be 16, I believe, but there is no way to unlock them. I'm basing my review on that one mission, which was fun and entertaining. I've visited flight sim forums and have found this to be a very common problem. Unfortunately, no one has come up with a solution. Too bad. This game has a lot of potential. My only hope is Windows 7. I'll try to re-install this game after I install Windows 7 when it comes out October 21.
