I've decided that mission 4 is impossible. After I hit the main target I don't get the prompt to egress to waypoint 6. So I assume it wants the fighters taken out. 4 of them launch initially, the AIM-120c doesn't really do anything unless you're within visual range, even then I have to hold my breath. I once had all of the initial fighters dead and then more scrambled and I caught a r-60 up my butt.
Sigh.
