On February 2, 2010, a regional airline flight from Nashville to Atlanta crashed during approach. Investigators found that the captain had failed to maintain airspeed, leading to a stall. The immediate conclusion seemed obvious: pilot error. The captain had made a mistake. He was the problem. But then investigators looked closer. They discovered that the captain had a history of failing check rides. They found that the airline's training program had been inadequate for years. They learned that the first officer, who could have caught the error, was fatigued from a commute that began at 3 a.m. They uncovered a culture where pilots were afraid to speak up about safety concerns because they feared retaliation.
