Fine posts, gums, thank you.
We have looked at some unofficial charts of the Airbus and it does not appear to to have the classic deep stall combinations of downwash or lack of nose down pitch moments due to c.g. as with the Viper In other words, it appears that if the crew had applied nose down stick and maybe nose down trim that the jet would have "flown out" of the stall.
IIRC there is the opinion that the aircraft could have been recovered from the stall, but opinions have varied regarding the altitude from which recovery could have been made. From what has been said, the elevators remained effective throughout the descent.
