Well, thanks mate.
Unfortunately YouTube decided to cut the soundtrack (and, together with it, the engine and bullet sounds...) I never got this issue with the videos anyway... Is my flight simulation video so important to them to cause the complete removal of the sounds?
Try to imagine it: Ride of the Valkyries starts right after the title, and when it ends, Eye of the Tiger starts.
EDIT: Maybe I'll try uploading it on Vimeo. As far as I know, they aren't that irritating about STs as YouTube is.
