I am not trying to speculate on what might have happened here, but have a read about the ICELANDAIR B-757 that was very close to crash during a go-around at Oslo Gardermoen in 2002 .
Shocking to see how quickly a well trained north-european crew nearly lost it during a standard procedure in an fully operational aircraft.
Pitch - 49 degrees, and lowest RA 321 !
