They didn't follow the QRH
With respect to you and your many followers here:
QRHs were around about 1969-72 for me (Hunter then F4). Airbus aircraft are a lot more sophisticated and, as you are doubtless aware, are not used these days.
Am I the first to admit I would have been severely challenged and, probably, overcome by the situation?
Mind you, I have only twenty years Airbus and extensive examiner experience.
What, in your opinion, is the core issue?
