It's somewhat interesting to note that Hüttig claims that no-one present at this simulation was able to get the nose down, while the data shows Bonin applied nose-up inputs almost throughout the accident sequence, which is Airbus' defense against the claim. And this latter info is what we here have essentially subscribed to, as if there was no other earthly possibility.
And yet, and YET.....Pprune posters still insist that the recorded inputs are either incompetent or inexplicable. I am still suspicious of this point.
To recap other info that's been presented here: it's been also said that there is no way to reproduce this stall in a simulator, since there's no air data from testing for such. Just trying to save us a few more rotations of the hamster wheel.
