There is probably no public space in American life that's more tightly controlled than an airplane. But everything isn't always as safe and sanitary as it would appear. These shocking facts, exposed by flight attendants, pilots and airport workers, may make you look at flying in a different light.
A very alarming survey of pilots in Norway, Sweden and the U.K. revealed that about half of all airline pilots have accidentally fallen asleep on the job. Thankfully there are co-pilots. Although there are alternating scheduled rest periods for pilots and co-pilots on longer flights, it's still sometimes not enough to prevent them from drifting off at the controls.
