If you look at the FDR plots you'll see that 5 secs before touchdown/impact, with the co-pilot flying at nominal speed and slightly above GS, the captain calls out "I got it" and reduces thrust to idle but both pilots abandon the control columns !! and the pitch goes from +2 to -4 degrees pitch until touchdown/impact.
No movement in the 2 control columns: forwards, backwards, turning right, or left are recorded i.e. no motion !!
After impact the left engine throttle almost goes to full thrust for over 5 secs.
There seems to be no captain-side GS data on the plots.
