planes and how i'm terrified of them

                I was actually reading the Art of Travel today and there was one part of the 2nd section that had to deal with planes, and the magnificence that it seemed to hold for De Botton. Where fear is the only thing that seems to grip me whenever I start thinking about having to fly, pleasure and contentment go through the arthur's mind. I only wish that that sort of resolve would flood my mind whenever I begin to think about airplanes.
               One passage during this section seemed to strike me as the most important question on my mind De Botton states "Similar sentiments may arise when looking at one of the larger species of airplane, it to 'vast' and 'complicated' creature which defies its size and the chaos of the lower atmosphere to steer serenely across the firmament. Seeing one parked at a gate, dwarfing luggage carts and mechanics, one is induced to feel surprise, overriding any scientific explanation, at how such a thing might move-- a few meters, let alone to Japan. " My question is, ok yea what the heck exactly holding this massive machines up in the air? I get the physics of it, yea but still. What keeps it from crashing down to earth? That is exactly why I am so afraid of these huge monsters. At any moment if something unexpected happens it could bring the whole thing down.
            That's why it makes me wonder what kind of peace and contentment that it holds for the author, and how exactly can I achieve that peace? My life would be so much less filled with anxiety over this issue if someone could tell me exactly what I need to do in order to not freak out every time I think about flying.
