If disasters breed groups, then groups need leaders. In a study of three mine fires published by the U.S. government in 2000, the eight groups that escaped each had a leader. The leaders had some things in common. They did not bully their way into power, but they got respect because they seemed calm and credible. They were, like Bailey, knowledgeable, aware of details, and decisive. They were also open to other opinions; in many of the escape groups, a sort of second lieutenant emerged to help the leader.
