The brief history of the 737 Max raises the question of whether Boeing made mistakes in its pursuit of efficiency. America’s Federal Aviation Administration (FAA) and other regulators will also have questions to answer about their oversight of the way changes to the plane were communicated to pilots.
As of the time of writing, it is impossible to definitively say if the two airplanes crashed for the same reasons. According to a preliminary report released by the Indonesian air safety investigative agency, Lion Air 610 crashed because a faulty sensor erroneously reported that the airplane was stalling.
The false report of a stall triggered an automated system that tried to point the aircraft’s nose down so that it could gain enough speed to fly safely.
The pilots fought the automated system, trying to pull the nose back up. They lost.
