Mental impairment vs capacity under stress is not discussed in the AAIB report of course, but the facts remain that the F/O stated that he was "afraid" that he might touch down on the runway edge while floating in the flare, and that his impression of the go-around being a "frightening and serious event" were reinforced - in fact, there are several references to the co-pilot feeling frightened in his stated comments, which to my mind, is not a function of dwindling capacity leading to the anxiety attack but rather some underlying issue. These were not extraordinary events but normal procedures that he should have been exposed to many times in basic and type-training. He left the cockpit during a critical phase of flight - this is the serious issue in my view and I find it hard to imagine a scenario beyond physical incapacitation where this could be deemed professionally acceptable.
