You don't scream at the boss. The first officer was afraid to say anything until just before the situation became dangerous. In other words, he was not as fearful of a controlled flight into terrain as he was of incurring the fury and explosive tongue of his captain.

Life is full of natural frustrations.
Life is not easy. There will always be pain, loss, injustice, and disagreements. In fact, long-standing unresolved anger is the main cause of being tired and depressed. It raises havoc with our general health. If you think you feel steamed most of the time, or if your anger is often out of control and you don't know why, make an appointment with a competent psychotherapist who deals in anger management.
