Boeing made many mistakes during the design process of the Boeing 737 MAX series aircraft. The MAX series is the successor of the NG (Next Generation) series of Boeing 737. As a result of these mistakes two brand new Boeing 737 MAX aircraft crashed in the same phase of the flight under similar conditions killing 346 people. The Boeing Company issued an apology and, for the first time, acknowledged its automatic flight control system (Maneuver Characteristics Augmentation System or MCAS) played a role in the two plane crashes.
