This is the result of the AI Mod Challenge I held 3 years ago. Sorry it took so long. XD
Thank you to everyone who submitted a plane. I included all of the planes that worked well.
If I have to pick a winner, since I called this a challenge, it is BogdanX, thank you for building those awesome planes for this. The F-16 is amazing!
This Mod adds 78 different low part aircraft into the game. They all take off from an airport, and have a destination airport. One plane is loaded into the game every 30 seconds, there might be a small stutter when they do load. It takes a while before things get warmed up, give it some time.
I made the planes on Maywar take off from the Terrace by the Windmills, for whatever reason. I may change it, IDK.
Anyway, Enjoy, and thanks again.
