Here is an attempt at it. Not too flash, and got a problem in the final stage when the missile is armed. Few intricaties in it, for instance, used the smokeshell first off to make an easier launch sequence, but problem is both the smoke shell and hellfire run out after about 8 secs each, so they need to be rebuilt. (deletevehicle, then camcreate exact same item with same stats.)
Problem still in the actual flight algoithm, brain not working tonight, will try it again tomorrow when have actually had sleep.
Hope it just gives you some ideas though.
