As anyone who's ever travelled by commercial aircraft in recent times, electronic devices have to go away during take off and landing. Now the FAA in the U.S has lifted the ban which could see other countries lift the ban Do people thing it's a good idea? It's long been claimed the interference risk from devices is non-existant (though even with the ban lifted, devices will have to put in aircraft mode). But to my mind there's another aspect. Take off and and landing are the riskiest parts of the flight, you don't want people distracted by electronic devices at a time when they might need to move quickly plus they can be extra clutter around the cabin when you might need to get out in a hurry.
