Lots of speculation about the cause of the crash landing at SFO. Consensus seems to build among Boeing pilots on the net that 777, configured for landing, quickly goes from “high and fast” to “low and slow” unless close attention is given to throttles to maintain speed. The Asiana pilots, for reasons not yet known, did not take over throttles manually when auto-throttles were inactivated. Apparently, heavy airplane pilots get very little “stick and rudder” hand-flying training or experience in the modern airline environment.
