Don’t drink and fly.

Words to live by, not just if you’re a pilot, but if you’re a passenger.

Sandra Langer explains why: On a recent trip from Amsterdam to New York, she watched a good number of her fellow passengers get hammered. “Red-faced men blocked the aisles, puked in the bathroom and groped the females — along with a laughing crew,” says Langer, a writer who lives in New York.

That’s right, some crewmembers were also inebriated. The trip made a lasting impression on Langer. “Never again will I take a connecting flight through Amsterdam,” she says.

Some airline experts insist in-flight snoozes improves overall safety.

Charles Lindbergh famously fell asleep while crossing the Atlantic on his historic 1927 solo flight, and despite strict federal rules against it, experienced airline pilots say it’s not uncommon to sneak a nap inside the cockpit.

The Northwest pilots who blew 150 miles (240 kilometers) past Minneapolis this past week insist a clandestine snooze isn’t to blame for their goof at 37,000 feet (11,300 meters). "Nobody fell asleep in the cockpit," first officer Richard I. Cole told The Associated Press.
