We know that the sink rate suddenly dropped at 200 feet AGL/1 mile/20 seconds out. Engines did not spool up until a couple of seconds before impact. From this, I think one can conclude that (given no flap changes that late in landing) someone pulled back the yoke. That would be beyond stupid at that point.
Maybe realized he was low and sinking, and pulled back the yoke instead of adding power? I thought “power for sink, attitude for speed” was the normal way of setting up your touchdown point for a landing in any airplane, be it a C150 or a B777.
