AIGs' flightplans do work. I used to have a delta connection AI pack, but since I de-installed my FS, it went lost.
I'll probably re-do it some time, but using higher-quality ai-aircraft/paints. All it takes is patience and concentration.
Remember, woai
is great, but unfortunately, they don't have permission from some freeware authors, but when you're on your own, you got the choice.
