Recently, a commercial airliner landing in San Francisco crashed on landing. It was definitely pilot error, as the plane was coming down to the runway too low and too slow, resulting in the wheels hitting the wall going down to the ocean below as it tried to land. The unfortunate thing about that crash was that if the plane was in autopilot, it could have landed itself, and the pilots on board could have kept their eyes closed. There were 3 pilots on the airliner at the time which is a requirement for a 777. The last video below shows the worst crashes in history.
