You enter a new realm when you walk down that jetway to the plane. From the unhappy bustle of the terminal, the lines for bad food, the flatscreen watching over all to remind them of the even greater misery outside, to the hush of the carpeted, windowless, downward slope, reeking of jet fuel suddenly, an uncivilized odor—no one would ever tolerate it for more than a minute but it’s intoxicating—to the independent nation of the plane, where there’s an otherworldly hum and colored lights glow from nowhere, and you can’t get reception now for some reason, and there’s a Muzak version of “Every Breath You Take” playing soft and low.
