Data from the jetliner that crashed into the Java Sea last month shows the pilots fought to save the plane almost from the moment it took off, as the Boeing 737’s nose was repeatedly forced down, apparently by an automatic system receiving incorrect sensor readings.

The information from the flight data recorder, contained in a preliminary report prepared by Indonesian crash investigators and released on Wednesday, documents a fatal tug of war between man and machine, with the plane’s nose forced dangerously downward over two dozen times during the 11-minute flight.

The pilots managed to pull the nose back up over and over until finally losing control, leaving the plane, Lion Air Flight 610, to plummet into the ocean at 450 miles per hour, killing all 189 people on board.

The data from the so-called black box is consistent with the theory that investigators have been most focused on: that a computerized system Boeing installed on its latest generation of 737 to prevent the plane’s nose from getting too high and causing a stall instead forced the nose down because of incorrect information it was receiving from sensors on the fuselage.

What the Lion Air Pilots May Have Needed to Do to Avoid a Crash

The rapid series of steps that may have been needed to save the plane were not in the manual, and the pilots had not been trained on them.
