Until the actual NTSB report is issued it is premature to draw any final conclusions, but a pretty clear picture is emerging of the cause of the Asiana 777 crash at SFO. There is no way to sugar coat this: the pilots fucked up. Worse, this was apparently not a fluke [see update below]. It was a result of deep systemic problems in Korean culture. It has happened many times before. It was so bad that the Korean airlines were on the verge of being blacklisted by the international aviation community. They thought they had the problem fixed, but apparently they don't. As the author of this piece [see update below] rightly points out, it is not so easy to change 3000 years of culture.
Commercial air travel is absolutely the safest form of transportation. You are safer on a commercial jet than you are in most places on the ground. But your odds worsen dramatically on Asiana or KAL. The Koreans build terrific cars. I love my Hyundai Genesis Coupe. But sadly they still don't know how to fly airplanes.
