At least one piece of the Boeing Co. 737-800 that crashed in China appears to have broken loose well before impact, a finding that adds mystery to the plane’s fatal dive.
The piece suspected to have come from the China Eastern Airlines Corp. Ltd. jet was found about 6 miles from the main wreckage area, Chinese officials said at a briefing Thursday.
If investigators confirm that the part came from the jet, it would indicate the plane suffered some kind of midair breakup, which could offer clues about what led to Monday’s crash or at least shed light on the flight’s final seconds.
