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.
