If craft with weapon in begin of assault ufo mission and located at same with ufo point, it can do airstrike in battlescape. At first turn virtual unit move from edge to edge of map and fire along flight path. We can select point for attack, type of strike (hedgehop with long attack path/dive with one point of attack). Craft weapon must have reference to battlescape weapon for this.
This have low grain/cost ration, lot of code to add one feature that will not be used in any other place. I prefer other way around.
Probably at some point this will be possible as side effect of other changes I will made (e.g. script spawning explosions on the whim).
For AI changes, its hard to tell how it will affect gameplay. If other people would like have it too then I could add this.
