Ok I just got a response back in the Offline Mission forum and at this time it is not possible to setup this scenario with the offline mission editor.
So my wish is either a change to the offline practice function as in my primary request of this thread or a change in the mission editor to allow picking a soft ack or a wirble instead of an aircraft to practice base defence from the ground. I suppose the ability to make the attacking aircraft circle the field and continuously fly down the runway at less then 1000ft in a rinse and repeat function is not available in the offline mission action control menu. But then I can wish for it here in this Forum......

It would still be nice to have a menu to change out the four aircraft circling the field. Adding a dive to the deck, run down the runway and climb back into formation would give the completely new palyer to Aces High a bit more of the physical situations that we shoot at in the MA. Slow left hand turns are nice, but only the very new player to Aces High ever gives anyone that guns solution in the MA. It does take a while before the new player moves into offline missons away from the default offline practice cons. Until that time, the new player with very littel experience knows that those 4 circling cons in offline mode work perfictly for thier given function as opposed to some of the unique things reported by players in getting offline missions to run.
Offline gunnery practice is integral to learning this game. It will not replace the Trainers, TA, DA, or time spent in the MA. But, by increasing the presentation of static repititious situations to practice gunnery solutions, you increase the possiblity of newer players gun solution success rates. This is still a buisiness and customers spend money when they are happy. Not when they are frustrated because they can't hit anything online.
