The aircraft’s cockpit voice recorder, discovered at the mountainous crash site in the Guangxi province, has been transferred to a National Transportation Safety Board (NTSB) facility in Washington, according to the agency. U.S. specialists are assisting investigators from the Civil Aviation Administration of China (CAAC) as they attempt to glean crucial details about the run-up to the tragedy.
An NTSB crash-investigation team also left Friday headed for China to assist the investigation.
