Those "idiots" that could not fly a visual, remember ? but the final NTSB report gives a very different picture that rather aim at the manufacturer and the airline than to the " idiots "pilots up front.
I hadn't seen the final report for this, thanks for pointing to it. But I don't think it supports what you say here. Both the probable cause and 3 out of 5 contributing factors relate directly to the specific performance of the crew, not to the manufacturer or the airline. Yes, the 777 autothrottle design seems highly perverse, and the airline clearly didn't encourage the kind of in-flight experience that would have equipped the crew to treat this approach as routine. But still, most of the reports fingers point at the crew.
Report conclusions below for those who don't want to wade through 129 pages. The Recommendations section is about training to prevent a recurrence, and therefore by nature says nothing about the specific crew - I'd imagine they won't be flying airliners again anyway so it would be irrelevant. Or if they are, they will have received a LOT of training.
The National Transportation Safety Board determines that the probable cause of this accident was the flight crew’s mismanagement of the airplane’s descent during the visual approach, the pilot flying’s unintended deactivation of automatic airspeed control, the flight crew’s inadequate monitoring of airspeed, and the flight crew’s delayed execution of a go-around after they became aware that the airplane was below acceptable glidepath and airspeed tolerances. Contributing to the accident were (1) the complexities of the autothrottle and autopilot flight director systems that were inadequately described in Boeing’s documentation and Asiana’s pilot training, which increased the likelihood of mode error; (2) the flight crew’s nonstandard communication and coordination regarding the use of the autothrottle and autopilot flight director systems; (3) the pilot flying’s inadequate training on the planning and executing of visual approaches; (4) the pilot monitoring/instructor pilot’s inadequate supervision of the pilot flying; and (5) flight crew fatigue, which likely degraded their performance.
