Compressor Stall,
This incident happened a couple of months ago as I recall.....We had just transfered to the first centre frequency south of Laravale and heard it all then. It was also a saturday morning so I don't know if all the frequencies in that area were combined!
Yeah it was scary to listen to.....I remember my other crew member saying " F*** that was one of the scariest things I've ever heard!! "
See Ya
