Appropriate Content for Airline Travel

A year ago, I tried to catch up on the first season of Lost during a long flight. I’ll be honest; I felt awkward watching a scene that depicted the violent turbulence of an airplane crash when I knew such a sight could make others nervous. It wasn’t likely, but I didn’t want to be impolite.

I only bring this up because I’ve heard a number of second-hand reports of air travelers watching porn in view of others while in-flight. It has always sounded like an urban legend to me since that behavior is so absurd, but I figure it has to happen now and again.

Good reader, what do you consider as appropriate content for in-cabin viewing? (Do you think it’s OK to watch porn on a plane?) Have you ever run into anything you’ve found questionable from a fellow traveler?
