Many people fear flying.
Often it is an incapacitating fear, and they are forced to travel by ground or water transportation. This fear does not respond to reason. Perhaps someone they knew was killed in a plane crash, perhaps it was something they saw on television or in a movie, or a bumpy airplane ride, or maybe it was a fear they picked up from somebody else. We have an inborn fear of falling and loud noises. When the ride gets bumpy you must remember that a wing hasn't come off a plane in at least 30 years.
