Guys: just one thing: I read somewhere that they went around like +3nm from the Runway Threshold, is that right ?
If it is true, then, at a 3 deg GP, 3nm give us something around 1000FT AAL...
At this altitude, no NOSE UP trim has been added in case of a Dual Channel Approach !
The Acft starts trimming around 400 ft RA.
I'm much more inclined to think that those guys ended up with a high nose up attitude during the Go Around (Low ALW, High Trust Setting, Maybe Somatogravic illusion), stalled and lost control of the aircraft.
