Ah, windows open inflight. I said this once before, but it always makes me smile when thinking about Mr. Goldfinger "exiting" the plane in that James Bond movie.

Not so smiling fact: There was a (real) incident where the Captain of the aircraft was sucked out after his windscreen collapsed. They held him back from actually falling, so he "surfed" the skies while his Co-Pilot managed to land.
Talking about being at cruise FL there, so he had some interesting minutes and actually survived this happening.

Back to the sounds, I've tried your suggestion, Diсk Everhard, but it didn't give me back the sounds. So the reloading still stays the only workaround for me.
Seems like this sound gauge on the 727 needs to be initialized twice to start working.
