If this is too far out of scope for this group, a moderator can feel free to remove this. I’m having trouble finding the flight simulation category. For the last 20 years I have been heavily involved in the development of the FlightGear open-source flight simulator. It’s totally free to download and fly! All we ask (and we don’t really ask this) is that if you have a good experience with it, pass the word along! http://www.flightgear.org
