Just a thought for those not considering a stall or part of one.
Reports of very strong LOW LEVEL jet have been around.
It does not indicate the direction of these winds. Maybe it can be derived from other data?
Should a sudden wind change occur during the missed approach, flying at clean speed up to possible even FL080, this could've possibly caused a stall on a wingtip, then (pitch) up and (wing) over is possible with this design when one one wing is affected.
Not saying this has happened, but with a speed of 197 it appears logical and thus possible as the clean speed for the aircraft is not much higher then this at the weights flown.
