Asiana 214 and NTSB Credibility
From the NTSB history of the flight (italics):
Pre selecting the missed approach altitude is common practice by B777 crews. However, setting an altitude above the aircraft without the flight guidance capturing and maintaining either an altitude or glide slope caused the autopilot to initiate a climb. The pilot naturally and appropriately disconnected the autopilot and manually flew the aircraft. Unfortunately, that unusual set of circumstances caused the auto throttle mode to remain in "HOLD" and not respond to the commanded speed as the crew expected.
Flight 214 was handed off to, but not acknowledged by, San Francisco Tower. In combination with the ATC imposed energy management complication, lack of electronic glide slope and flight guidance mode confusion, this was another significant distraction.
