Yeah this is all pretty baffling at the moment, I can't even figure out how to make something simple like a successful landing at an airfield trigger a success event.
Mind you I did get a bit distracted by the Herring Gulls object that I was playing with.
Bit of an FPS hog though
Anyway its early days, we'll get the hang of it soon enough ...
BTW we've been able to add .wav files to briefings since Pacific Fighters

just need to work out the correct file format; I bet its the same as for IL2...
