What did Boeing know about the potential for disaster with its 737 Max passenger jet, and when did the company know it? Tom Jennings, director of the FRONTLINE/New York Times documentary “Boeing’s Fatal Flaw,” and Times reporter David Gelles detail what their findings reveal about the lead-up to the two 737 Max plane crashes in 2018 and 2019 that killed 346 people. 

In conversation with FRONTLINE Executive Producer Raney Aronson-Rath, Jennings and Gelles discuss what they learned about the technical issues with Boeing’s fastest-selling commercial jet, as well as how market pressures, corporate culture and failed regulatory oversight ushered a plane with a fatal design flaw into commercial service. Jennings and Gelles also discuss what’s changed since the crashes — and how they’d each feel about walking onto a Boeing plane now.

The documentary “Boeing’s Fatal Flaw” is now streaming on FRONTLINE’s website, the PBS Video app and FRONTLINE’s YouTube channel.
