Possible solution: damage an aircraft upon player exit to make it fall down and destroy it later in 10 minutes after it hits the ground.
2) When AI bombers are scripted to reappear on a server as time goes by the server can become very crowded with AI bombers making it unplayable. Mission example http://forum.1cpublishing.eu/showpos...8&postcount=24
The solution would be to damage AI bombers one by one (with 1-2 min intervals) in 15-25 minutes after their last waypoint. OnTaskCompleted()? Then when they fall down destroy them in 10 minutes.
Ideally damage applied to aircraft should be different (say 10 different types of damage in rotation) but deadly enough to make aircraft fall down in 1-3 minutes.
