I once read a story about a Korean aircraft hitting a mountain where the blackbox recorded the last minutes. They copilot and engineer (used to have those too) would only speak up a few seconds before impact. Before that they would only make vague mentions of being off course. It seemed and still seems unbelievable that someone chooses death over telling a superior that he is wrong.
