In this episode, Gill Kernick and Matthew Price examine what went wrong with the Boeing 737 Max aircraft. Why did 346 people lose their lives? With the help of the consulting editor at Flight Global, David Learmount, Gill and Matthew look at the culture of Boeing at the time of the accident, and find out why not even the pilots of the new plane knew about MCAS - a new technology that led to the disasters. They speak to retired NASA Astronaut Jim Wetherbee and domestic airline pilot Laura Einsetler about the importance of listening to the front line and how if bad news is well received we stand a better chance of avoiding catastrophe.
