In the accident flight, the first officer (FO) inadvertently activated the "go around" mode during landing, then, in surprise, pushed the airplane into the ground.
> According to one check airman at [FO's previous airline], the FO could explain things well in the briefing room and performed some expected tasks well in the simulator. However, when presented with something unexpected in the simulator, the FO would get extremely flustered and could not respond appropriately to the situation. She said that when the FO did not know what to do, he became extremely anxious and would start pushing a lot of buttons without thinking about what he was pushing, just to be doing something.
