Most people have a fear (0) of heights. This is a reasonable survival trait! However, (1) coupled with extreme media coverage of disasters, this can lead to a very debilitating fear of flying. Furthermore, for many people, not having any control of the plane makes (2) fear worse. It is not unlike how one usually worries more as a passenger in a car than (3) a driver of a car.
This is not necessarily a rational fear, if we looked (4) it in the context of all possible hazards. There are far fewer fatalities per airline passenger-mile (5) there are per automobile driver-mile.
Personally, I lost all fear of flying after living close to an airport for a (6) years. The airplanes kept going up and they kept landing. Over and over and over again, hundreds of times (7) day. And never once did a plane crash at that airport. This made (8) understand very clearly just how safe air travel is.
If all this logic doesn’t help you, join (9) club of thousands and do what they (10) : get drunk before you get on the plane!
