Lion Air Flight 610 was just 13 minutes into flight from Jakarta, Indonesia, when it plunged into the sea on 29 October 2018. This was the first fatal aviation accident for the 737 MAX, killing all 189 people on board. Just 5 months later, tragedy struck again on 10 March 2019, when the 737 Max serving Ethiopian Airlines Flight 302, crashed approximately 6 minutes after takeoff from Ethiopia, once again, killing all passengers and crew. What followed was an intense investigation into what caused these two devastating crashes. In this episode former NTSB investigators talk us through how these tragedies could have been avoided.
