What part of the flying, precisely, are you afraid of? As soundedfury said, you are statistically safer flying than many other things you do on a daily basis. But it’s understandable if that’s not terribly calming. Numbers and statistics rarely are. Instead, consider why you’re so much safer flying.
First, know that your captain and copilot will be extremely experienced pilots, each with thousands of hours behind the yoke of that particular type of aircraft. Consider that even 1000 hours is the equivalent of six months’ worth of 40 hour workweeks. Imagine spending eight hours a day, five days a week, for six months doing nothing but flying one type of aircraft. Your pilots will have done the equivalent of that many times over.
Additionally, each plane must be thoroughly inspected on a regular basis. That includes daily, weekly, turnaround and annual inspections, in addition to engine and airframe-hour specific inspections. Each inspection must be performed by highly qualified maintenance personnel utilizing very specific checklists and equipment.
That aircraft you will be flying on is the product of millions and millions of man-hours of design, engineering, building, inspecting and testing. Every single part used to put it together will have been seen by countless eyes before ending up on the plane. The technology used for the design, production and testing is some of the best in the world, not to mention the technology aboard the plane itself. It has been flown many times before without a serious incident, and it will be flown many times again after you disembark.
Your flight will be the result of the combined efforts of tens of thousands of extremely smart people—engineers, scientists, flight instructors, maintainers, pilots, test pilots, computer programmers—the list goes on and on. Each one of those people has a stake in the success of your flight. They won’t let you down.
Well, they will, but slowly and in a controlled manner.
