You have control, simply make the next segment attack or patrol.

So this occurred when they had several patrol segments. Eventually they had segments for their pattern and landing. Eventually you at least have to have a landing segment.
I had intercepted the patrol, activated their combat mode then started dragging them back to my side toward friendlies so as to even the numbers. The dragging and engaging cycles were enough to burn through all their patrol segments I guess.
In the middle of a dogfight they stopped and started to fly home to enter their landing pattern. Which means I then just fall in behind them and shoot them in the back.
Regardless if I had burned through all the patrol segments up to their landing segments, they shouldn't just go brain dead in the middle of a shooting fight.
You can't always predict how long combats are going to last.
An alternative would be to have a sane defensive mode behavior they can drop in to if being shot at , even if they are in cruise or landing mode. It never really makes sense to ignore an enemy 50yd on your six shooting you.
