On the day of the accident, the first thing that struck me was:
Practise emergencies in the SIM, immediately afterwards practise an emergency in the real a/c early in the flight.
The use of emergency selections for gear / flap around the time of the ATC call ("distraction") might tend to confirm a capture of the wrong environment.
(Would those selections affect a go-around? eg Do those EMG selections now override normal selections?)
Clearly, there was overload and, as said above, an escape plan (simple gate?) would surely have helped.
