Let me try to work through a few of the leads, responses, red herrings, and insights that readers have sent in since the crash two weeks ago.
This is the best video I've seen so far demonstrating the cost of a flat approach. The only misleading element is the airspeed differential, probably to keep the two images in close proximity. The dramatically slower approach speed of the aircraft would have better highlighted the flaw, not just in altitude above the ground but the equally dangerous decreasing airspeed. The properly positioned "ghost" aircraft would have left the doomed Asiana far behind - running out of altitude, airspeed, and options.If your own flight instructor never told you - get on the proper descent profile as soon as possible. Being high or low is a formula for a more challenging landing. Waiting to correct for being high, low, slow, fast, or off center means "going to school" much too late - no rodeos required. With this international route, a good crew has been efficient for the last 12 to 14 hours and nine time zones of circadian shift, so a stabilized approach is the primary consideration during the final minutes of flight.
2) What's wrong with "Confucius in the cockpit" / "this is how Asians fly" hypotheses. If you've been following this topic, you've seen countless circulated emails from Western pilots alarmed at what they have seen at Asian, and especially Korean and Chinese, flight schools and airlines. I don't have time to fish these all out at the moment. I will say that if you'd like a bracing retort, the place to start is with the "Ask a Korean" site, notably this post (which goes right at Malcolm Gladwell-ism) and then this omnibus followup, including a reply from Gladwell.
When I can I will try to give a Solomonic pronouncement on winners and losers in this dispute. Two-sentence preview: Of course Asian-style education and culture can lead to distinctive dynamics in the workplace or in an airline cockpit. But I'm skeptical of moving directly to civilizational interpretations of events with more modest potential explanations. (OK, a third sentence: At face value it appears that for some reason there was a failure of basic flying skills here, but just the same appeared to be true in the 2009 Colgan crash in Buffalo, whose two home-grown American pilots had no known connection to Confucianism.)
