However this had not been rolled out when an Ethiopian Airways’ 737 Max crashed 4 months later, killing 157 individuals.

Presently 737 Max planes are grounded worldwide amid issues that an anti-stall system might have contributed to each crashes.

Boeing is within the technique of updating the system, often known as MCAS, however denies it was solely accountable for the disasters.
