Under the direction of filmmaker Rory Kennedy, the youngest child of Robert F. Kennedy, “Downfall” recounts how the aerospace giant cut corners in a race to compete against Airbus, and pressed mightily to minimize the known problems with a computerized flight control system that was capable of causing the 737 MAX to go into a fatal dive.
The result? Not just one, but two catastrophic crashes — first in Indonesia, in 2018, and only months later in Ethiopia. The combined death toll amounted to 346 people. The jets were grounded for nearly two years while Boeing worked on a fix to the control system.
When the Indonesian crash occurred, the root cause seemed to be shrouded in uncertainty. But subsequent investigations showed that Boeing knew the cause had to do with tweaks in an automated software routine known as the Maneuvering Characteristics Augmentation System, or MCAS.
In the early stages of those investigations, I struggled to explain what MCAS was supposed to do (keep planes from stalling under extreme conditions) and what it ended up doing (forcing planes into a dive). “Downfall” uses graphics and re-enactments to show how MCAS and other points of failure on the 737 MAX figured in the tragedy.
The film also lays out evidence from emails and other documents showing that when the 737 MAX was undergoing certification for flight, Boeing was desperate to avoid providing pilots with extra training, at extra cost — so desperate that the company hid the MCAS software’s capabilities from pilots, airlines and regulators.
