I’m not an especially fearful flier, but I dread turbulence all the same. I avoid seats in the back of a plane, check radar maps before a flight, and keep my seat belt buckled even when the light is off. I remember a conversation I once had with the forensic anthropologist Clyde Snow, who spent years investigating plane crashes for the F.A.A. In his experience, he said, when a crash did have survivors, a disproportionate number of them were men: they were the first to shove and claw their way to the exits. As he put it in 1970, in a study that included two plane crashes in which the passengers had to flee from burning cabins, “It appears that younger males were definitely favored . . . where speed, strength, and agility would be expected to play a dominant role.” In those two crashes, even the old men survived at a higher rate than the adult women and children.
