My recollection from many years ago was that the B744 clean stall was defined by deterrent buffet.
Boeing certainly did not stall this aircraft unless the tailplane was strain gauged. There was no correlation between the buffet levels experienced by the test crew and that experienced by the tailplane - structural damage could result.
I recall hanging around Boeing Field awaiting completion of strain gauge installation on a B744 up at Everett.

LS states that he experienced mild encounters which I assume was from other 747s. If it was an initial encounter with wake turbulence I would also expect that mention would be made of that in the ATSB summary.
Yes can, will and does. Covered already.

Had the [email protected] kicked out of us flying into AMS recently following one of those little 737 aeroplanes. We were in a 380. Have also been rolled left and right following 777, 747, 757, 380 while also in a 380.

The challenger being discussed, may have been bent from a less than graceful recovery.

Had injuries on a 767 years ago when at FL370 about 10-15 miles behind a 744. Had the A380 thrown sideways and A/P disengage behind another A380 into DXB. I can absolutely see the right kind of wake getting a 744 at min speed into an UAS.

Thank you.
I am not a pilot, I'm not in the airline business either just a passenger onboard, I might not have the correct phrases you require. I'm just telling you how it felt on board that plane. Trying to shed a light on what might have happened that's all.
