This Der Spiegel article was posted earlier by someone else, but resulted in zero discussion:
It adds nothing to the discussion but some highly tendentious speculations...
According to the BEA's interim report, the horizontal stabilizer moved from three degrees to 13 degrees, almost the maximum. In doing so, it forced the plane into an increasingly steep climb.
As far as we can gather from the report, at least initially not the THS forced the plane nose up, but the stick input did.
2h10m51:
Stall warning
(...)
PF maintained nose-up inputs
(...)
The trimmable horizontal stabilizer (THS) passed from 3 to 13 degrees nose-up in about 1 minute
(...)
The PF continued to make nose-up inputs
(...)
2 h 11 min 40:
The PF made an input on the sidestick to the left and nose-up stops, which lasted about 30 seconds
2 h 12 min 02:
Around fifteen seconds later, the PF made pitch-down inputs. In the following moments, the angle of attack decreased
This is the first mention of any nose down input after the stall warning, 1m26 later. It is not known how long this input lasted (and BTW it is also not known whether PF ceased the ND input due to the reactivated stall warning, as many here claim).
Forty-one seconds before impact, both co-pilots were pushing on the controls.
We don't know that. The report states merely:
simultaneous inputs by both pilots on the sidesticks were recorded
Then Bonin cried desperately: "Go ahead, you have the controls."
Report says:
and the PF said "go ahead you have the controls".
Admittedly probably not dramatic enough for a "serious" publication.
The passengers, who had just a short time before been pressed into the backs of their seats, were now being held into their seats only by their seatbelts.
Which would necessitate a continuous downward acceleration. We know downward velocity at 2h11m40 to be -10000 fpm, final velocity at 2h14m28 to be -10912 fpm.
They appear to have reached terminal velocity pretty early on.
