United Airlines says it plans to become the first major airline to carry "taser" stun guns in the cockpits of all aircraft, provided it gains approval from the US Federal Aviation Administration. United says it plans to carry the high-voltage weapons in an electronically locked box in the cockpit, accessible only by pilots. US regional Mesa Airlines was the first to announce plans to arm pilots with tasers, but the FAA has yet to approve the carriage of the weapons on aircraft.
