FS9/FSX. Well I assume there is an FSX version although I cant seem to find the FSX page. I also assume this is freeware although I am not fully certain. What I will say is the Indonesian team has sneaked up pretty quickly on us with this new destination. I don't really have much more information on this so as always I will provide the source link (sorry some of you don't like it's location) below and thanks to ADX reader Thomas Klein for the tipoff. I'll update this post soon as I get more info.
Update: Source link updated with FSX version download.
