I recently flew more than twelve thousand miles in a little over a month, through rain, fog, wind and snow, over mountains, cities and deserts, in a three-year-old, second-hand airplane that had already traveled some five hundred thousand miles. During that time I never was very late for an appointment or put a single scratch on myself. And considering that I am hardly an expert pilot at nineteen years of age, I knew that these statements must prove something about modern commercial aviation.
