Actually I had the same problem last night no matter what mission I tried. No matter what I did the friendlies would instantly blow up on the runway in the giant sprawling fireball (as if pilot killed) and I never got text, mission waypoints, could not get the mission going.
It was a fresh boot, hadn't gone offline in a long time (but last time I did the missions worked). I tried going to the TA then exiting out like some suggested to fix the missing text from long ago, it didn't help.
Then if I bailed to start over I don't know if it really ended the mission. The drones orbiting the airfields never came back.
Some strange stuff is going on with AH, and it didn't before.
