In the book “Outliers,” the author has an entire chapter on Korean culture, and how it makes their airlines by far the most dangerous in the world. The copilot won’t so much as suggest a correction lest it shame the pilot.
Outliers by Malcolm Gladwell
One entire chapter on why Korean airlines are many times more dangerous than others.
That attitude was a major contributor to the Tenerife runway collision in 1977. a KLM co-pilot was unwilling to correct the airline’s most senior pilot a second time for the same error.
