There needs to be some kind of AI aircraft.
So there is AI ships, a AI convoy, and a AI anti air missile silo in the sandbox mode. But there is no AI aircraft. AI aircraft need to be added to simple planes. And I have a few suggestions that could be put into the game.
1. Pleasure craft (small aircraft)
2. Commercial aircraft (passenger planes)
3. Military patrol aircraft (F-16 and such)
4. A refueling plane (so you can refuel and rearm your aircraft on long term flights)
5. And a few hostile aircraft in a certain airspace
(Like MIG-15's or MIG-21's)
Thank you for reading my suggestion.
I'm pretty sure there is a AI aircraft, I think it is called "Bomber" but maybe I just couldn't find it in my planes list.
