Over the last year, flying with phones and other devices has become increasingly dangerous.

In September, a passenger was arrested in El Paso after refusing to turn off his cellphone as the plane was landing. In October, a man in Chicago was arrested because he used his iPad during takeoff. In November, half a dozen police cars raced across the tarmac at La Guardia Airport in New York, surrounding a plane as if there were a terrorist on board. They arrested a 30-year-old man who had also refused to turn off his phone while on the runway.

Who is to blame in these episodes? You can’t solely pin it on the passengers. Some of the responsibility falls on the Federal Aviation Administration, for continuing to uphold a rule that is based on the unproven idea that a phone or tablet can interfere with the operation of a plane.

These conflicts have been going on for several years. In 2010, a 68-year-old man punched a teenager because he didn’t turn off his phone. Lt. Kent Lipple of the Boise Police Department in Idaho, who arrested the puncher, said the man “felt he was protecting the entire plane and its occupants.” And let’s not forget Alec Baldwin, who was kicked off an American Airlines plane in 2011 for playing Words With Friends online while parked at the gate.

Dealing with the F.A.A. on this topic is like arguing with a stubborn teenager. The agency has no proof that electronic devices can harm a plane’s avionics, but it still perpetuates such claims, spreading irrational fear among millions of fliers.
