I remember in the good old days there was an utility which instant traffic was generated without the need to use traffic tools or compile a bgl. I could just start any traffic with my aircraft library.   Also I remember being able to generate helicopter AI traffic. Another one (if not the same) would create AI traffic to follow your plane with the option of being in formation...I just can't remember its name ... help!!

 Perhaps ga-traffic_setup.zip by Markus Brunner?  

Never used it so don't know any more than what's in the description.

HI Steve I downloaded that and will check it out later thanks.
