The pilots of the Asiana Boeing 777-200ER that crash landed at San Francisco International Airport on Saturday had armed the airplane’s autothrottles to maintain a 137-knot landing speed, leaving National Transportation Safety Board investigators questioning why the airplane slowed to 103 knots three seconds before it hit the sea wall at the threshold of Runway 28L.
