One of the most despised in-flight rules may be lifted this week. If all goes according to plan, the FAA will allow passengers to use offline electronic devices during take-off and landing — that means watching a movie on your iPad or reading a book on your Kindle would be fair play.

Where did this rule even come from? Molly Wood, executive editor at CNET and host of CNET’s Always On, says it came from a legitimate place before morphing into something outdated. On older planes with unshielded wiring, it is possible for certain wireless devices to interfere with a pilot’s communication efforts, but that doesn’t apply to an iPhone on airplane mode.

“To be honest, flight attendants and pilots report that at least a third, if not more, of people on every plane just forget to turn off their phones,” she says.
