When a China Eastern Boeing 737-800 crashed into the earth in March, the impact caused a 65-foot-deep crater and smashed the plane into tens of thousands of pieces, some of them buried underground by the force. The Wall Street Journal now reports on a preliminary assessment of what caused that catastrophic impact, which killed all 132 people aboard: an intentional choice, sources close to US officials' initial assessment tell the paper. That assessment factored in an analysis of what was pulled from the damaged flight-data recorder, and the data it held suggested "inputs to the controls" caused the dive, as the Journal puts it. "The plane did what it was told to do by someone in the cockpit," says one of the sources.
What isn't clear is whether such an action would have been committed by the pilots or by a passenger or crew member who forced themselves into the cockpit, though in response to questions about whether this was a possibility, China Eastern noted there was no emergency code activated that would have indicated this occurred. The airline has reiterated that thus far it has determined those piloting the plane were in good health, with stable families and no financial troubles. Barron's reports Boeing stock jumped on the news. It was trading up about 6% as of this writing. Indeed, the Journal notes that its sources say no one inside Boeing and no regulars are said to be working on service bulletins or safety directives related to the crash, suggesting they have uncovered nothing concerning that airlines and crew need to know about the plane.
