In my opinion, the only thing that needs to be fixed on that mission are the last 5 minutes where nothing happens. At all. -.- Other than that, that mission is perfect. It's hell, but perfect.
As a more general suggestion, I'd like some breathing room during some of the missions. Especially for dialogue. Now I can't remember exactly during which missions but I do remember having a lot of dialogue going on during intense fights and having to press F4 to stop and read the messages. This surely isn't such a big deal, but having a few seconds for you and you wingmen to speak shouldn't hurt much. I think.
Btw, I just finished this campaign and I loved it. It's awesome.
