Multiple news organizations are reporting that Boeing's board decided to fire Muilenburg over the weekend. > Muilenburg's departure caps a disastrous year for the aerospace giant. Two deadly crashes of Boeing's new 737 MAX—one in October 2018, the second in March 2019—forced airlines around the world to ground their planes.
