Not sure if this is just me but I feel like the scripting in the second mission isn't working properly. It took me a few tries to actually get Dust Lance to the airfield, but when I did and killed all the targets all the dialogue stopped and the mission failed automatically at 14:10 to go. I'll try and replicate what I did/swap aircraft to see if it's tied to a specific aircraft/weapon or something. I tried it with the F 4 using double small bombs, standard missiles, and Saams.
