I saw a video on this the day after the first instance. The sensor was at fault, but once they figured out that the plane needed to be manually flown, they had to correct the AOA manually with a large flywheel like control under the throttle/thrust console. In the demonstration, they had spin the wheel what looked like 10-15 revolutions. At that point the simulator overshot the correction and the co-pilot was left chasing the correction, like loose steering.
I wonder if "Skully" could have flown out of it? He did an amazing job in the river landing.
