Why i'm afraid of flying.

I don't like to fly, heck, who does? I just never liked the idea of going up in the sky in those giant metal birds. Well, to tell you the truth, i'm a pessimist. I can admit that. It's not that i purposely want anything bad to happen, it's just that i get a bad feeling. I do pray that all goes well, and it has, i've always gone where i've had to safely and i pray that things will continue like that. People say that nothing ever goes wrong with airplanes and how statistically, more people die in car crashes. That's all fine and well, but what the heck is all this?
