- Thereafter stable at implausibly high AOA.
- Moments before the final crash, the aircraft entered a negative-g bunt, AOA sensor flipped 180 degrees, stick shaker stopped.
Already hinted before in this thread, but the only physical explanation consistent will all of these data points is vane detachment. The event is clearly different from Lion Air, which had a constant 20 degree offset, but the end result was the same.
