Despawner, I have taken the original code and added reset timers, many of the current users use hard code, if you leave the aircraft the plane despawns. The issue for me with this is in the case of controlling a flight of planes. Eg taking a flight of light bombers to a target and swap from plane to plane to bomb the area then take them home again. Why not!

Anyway I set a timer running on creation, on place leave and added on task completed. I actually have 3 timer periods, set via the editable inputs near start in constants and parameters section. I also added ground object removal for objects after the first base mission. The default is 45mins so be aware of what is going on.

    /*
    despawner timer added to original code, sets overall time period for actors,
    Advantage is, if delayed, say trying to land behind masses of planes, actors despawn at timer period set anyway.
    allows for players to fly groups of planes, 
    Player can re eneter flights or groups, as bombers take them to target, use each at target then fly group home
    despawn only triggers once player leaves whole group
