To some people, there is no noise on earth as exciting as the sound of three or four big fan-jet engines rising in pitch, as the plane they are sitting in swivels at the end of the runway and, straining against its brakes, prepares for takeoff. The very danger in the situation is inseparable from the exhilaration it yields. You are strapped into your seat now, there is no way back, you have delivered yourself into the power of modern technology. You might as well lie back and enjoy it.
