Trigger Zone and the Dog Fight that never ends.

[RoadKing2017]

Trigger zone question.  Has anyone set up a trigger zone (when you fly through it) that spawns a new, looking-for-blood, preconfigured opposing aircraft?   Basically, I'm looking for a dog flight scenario that never ends.  Like the song.   I don't see anything in the Actions (far right) section that says anything like SPAWN NEW OPPOSING AIRCRAFT.  Or some such thing.

there is no action like that, you need to use Lua scripting in order to spawn units, with just trigger actions you can only activate pre-defined units. A middle ground alternative is to use a tool like DML (by @cfrag )
