Crew Sound in FsP

[blow_water]

When I check the SoundText.fst, I found out that there are many sound that do not appear in FS2004 before
e.g. cruise_long1.wav(Hostess to pilot: I don't like these long flights... there is not much to do on board.)

How can I make in appear randomly while in my flight???

You can't, not all of the sounds are in use (yet)
