It could well be the Continental event that I was thinking of (although I was thinking it was early 1980s, not late 1980s) - basically going off 25 year old (or maybe older) memory of a second hand account.
I wasn't involved in that investigation - just remember hearing the story. I do remember being told that the surge was caused by over-rotation, however the JT9D was notorious for that so it may have been embellishment by the teller....
Rick777 - what I recall KC135 driver telling me was that "they" had a handle to start jettison - I just assumed it was the flight engineer (I am rather surprised to hear the KC135 didn't have one - they must have kept you guys driving busy). As for the 'handle' part - again it may have been embellishment by the teller. A "handle' does make for a better story than a "procedure"
Again, I was just trying to make the point that fuel jettison can happen well below the altitude where the authorities would like it to take place.
