Until you find a mission replacement, I can add various bomber objectives (so you guy's dont' feel left out). Someone would have to test those as it would probably take me 20 goes to land a bomb in the right place, lol.
Currently adding a fuel truck convey - with a destination to a fuel yard (big boom - nice find to the guy who posted about that in a thread).
I'll look into getting trains working too, as another objective.
Ships could be another tasty objective.
