Investigators looking into the crash of a China Eastern Airlines jet are examining the actions of the crew on the flight deck, with no evidence found of a technical malfunction, two people briefed on the matter said.
In mainland China's deadliest aviation disaster for 28 years, the Boeing 737-800 crashed in the mountains of southern Guangxi on March 21, after a sudden plunge from cruising altitude, killing all 123 passengers and nine crew.
