The air is annoyingly potted with a multitude of minor vertical disturbances which sicken the passengers and keep us captives of our seat belts. We sweat in the cockpit, though much of the time we fly with the side windows open. The airplanes smell of hot oil and simmering aluminum, disinfectant, feces, leather, and puke ... the stewardesses, short-tempered and reeking of vomit, come forward as often as they can for what is a breath of comparatively fresh air.
