According to Reuters Asia, the China Airlines 747 crashed while it was on autopilot. This was determined from the recovered flight data recorder of the plane. Autopilot was on until the very end when the recorder stopped recording. However, the cockpit wreckage shows the autopilot as having been disengaged.
Hmmm.... does this mean pilot error can now be ruled out? Are there other crashes that occurred while the aircraft was on autopilot?
