Is there any way to modify the sound files to include real world safety briefings?  Ie, instead of the standard FS2Crew voice doing the safety briefings, use an uploaded sound file of a real world airline (Qantas, AA etc - you can get them all on youtube).

Otherwise, could this be a feature in a future update?  It would make FS2crew even more realistic.  

Not possible since our sounds are compiled directly into the program.

Best,
