This is slightly off topic, but Flightaware had a Youtube link to a very interesting video of an animation produced by the U.S. NTSB about the 777 crash at KSFO.  It details the crew actions with the autopilot and flight controls leading to the low approach and hitting the seawall.  It is a good example of how NOT to use the autopilot for landing.
