A crew member may have intentionally steered a China Eastern plane into its fatal dive, flight data from a black box recovered in the wreckage suggest.

Someone in the cockpit pushed the controls that forced the Boeing 737-800 to plummet suddenly from its high-altitude cruising speed into the side of a mountain, killing more than 100 people on board, people with knowledge of the crash assessment told the Wall Street Journal.

"The plane did what it was told to do by someone in the cockpit," one person said.

NO SURVIVORS FOUND IN WRECKAGE OF CRASHED CHINESE AIRLINER

Chinese officials leading the crash investigation haven't identified any mechanical or flight-control problems with the jet involved in the March 21 crash, leading U.S. officials involved in the investigation to turn their heads to the pilot.

The airline echoed remarks made in March that the aircraft pilot was in good health and had no apparent financial troubles at the time of the crash in a new statement to the outlet.

Both of the plane's black boxes were recovered from the wreckage, including the cockpit voice recorder, which records the cockpit crew's conversations and background noise, and the flight data recorder, which records information about the plane's airspeed, altitude, direction, and more.

No survivors were found in the days following the crash, with officials later declaring all 123 passengers and nine crew members dead.

The black boxes are still being analyzed, officials said.
