This reminds me of a section in a book (I think it was Outliers, by Malcom Gladwell), where he pointed out that asian airlines had some of the highest accident/incident/near miss rates of major carriers, I think Korean Air was one of the highest. His analysis pointed to thet amount of deference shown by copilots to the pilot, and even in interactions with air traffic control, because it would be considered disrespectful to correct the Pilot, so small errors or oversights, that would usually be caught or corrected by the navigator or co-pilot, were frequently not addressed. It's been a while since I read it, but IIRC they actually did some comparisons with survey data to identify the most 'deferential' cultures, and how those results correlated with who was actually on the crew in certain incidents.
This was one of the primary causes for "Shiga" -- a JAL DC-8 -- landing in San Francisco Bay in 1968. I studied this one as part of my Aircraft Accident Investigation class, and what made it worse was that one of the crewmembers was actually an American (IIRC, it was the flight engineer). Besides landing short of the runway, they had some navigational issues, such as flying past the approach path, due to a fatigued captain and a crew that was unwilling to correct him.
It is true that KAL used to have one of the worst safety records in Asia and, indeed, in the world among major airlines. They have improved greatly over the past decade or so. The same, unfortunately, cannot be said for Russian airlines, or those based in Africa or the Middle East (which is part of Asia, thus the continent's poor rating). They've improved, but not enough that I'm willing to fly on some of them (the largest Middle East airlines are okay -- Qatar Airways, Emirates Air -- but most of the others are suspect).
