A Boeing 737 Max 8 airplane being built for India-based Jet Airways, takes off April 10, 2019, on a test flight at Boeing Field in Seattle. Boeing said Sunday, May 5, 2019, that it discovered after airlines had been flying its 737 Max plane for several months that a safety alert in the cockpit was not working as intended, yet it didn’t disclose that fact to airlines or federal regulators until after one of the planes crashed.
