A/S seems a tad high, I wouldn't discount the turbulence in an area that it's suggested is known for it, with the newbie owner flying along - encounters some clear air tubulence - dust devil or whatever, they can go higher than 6000 and be violent up there in the desert here in oz- he panics - mate wakes up just a bit too late - ?????
certainly IF they encountered such scenario at a high power setting it would not help.
BA, I got to hear about your story from a friend, now deceased, who happened to be flying a mirage on finals when the good old aussies - after some head scratching and some time later - sent up a second machine to test fly the same scenario.
The test pilot was a friend of my mate, result was - ahem! well - predictable in hindsight - maybe foresight too - not the best thing that my mate reckoned he had seen.
