How does the plane crash in Korean Airlines tie into culture of honor in Outliers?

Gladwell explains that the culture of honor prevents people from
admitting that they potentially may have made a mistake; also the culture of honor prevents
people in lower positions in social hierarchies from challenging the decisions of those in higher
positions. Gladwell outlines the conversation that occurred between the pilot and his subordinate
just before the crash--the subordinate knows that something is very wrong, yet he does not
directly tell the head pilot of his concerns. Instead, he attempts to allude to the problem, but
the head pilot follows his own plan. Gladwell says that the interplay between the two men is
bound by the culture of honor, so much so that the subordinate lost his life rather than break
social custom.
