I've never developed anything for any simulator, just have helped beta testing things (Maddog and Majestic Q400) as I was a pilot on both aircraft. I am wondering if it's possible to breath back to life the old adventure file of Stefan Gerlach's "LH4384"- a lufthansa flight from Frankfurt to Nice that uses ATC recordings and was extremely well done back in the FS98 days. Basically what I think happened in these adventures is the aircraft would pass over a waypoint/set of coordinates, and then the appropriate ATC wav file would play. Would the bush mission creator be a good tool to attack this project?
