"Don't charge your phone in the bathroom's shaver socket" may become a standard airline warning after an emergency landing yesterday. A Delta Air Lines flight from Istanbul to New York City landed in Dublin after one passenger left his phone—with its charger wrapped around it—in one of the plane's bathrooms, and another flier reported it might be a bomb, CBS reports. Irish police officers boarded the plane, determined there was no threat, and asked any passenger missing his phone to come forward. The aircraft was refueled and allowed to continue its journey.
