Downfall: The Case Against Boeing is an accessible, emotionally forceful account of the two 737 MAX crashes—and an argument that their causes reached beyond a faulty system. Its central insight is that safety-critical technology does not fail in isolation: design, pilot information, certification and corporate decisions all shape what happens when something goes wrong.
A documentary with a clear case to make
Directed and produced by Rory Kennedy, the 2022 Netflix documentary Downfall: The Case Against Boeing investigates the crashes of Lion Air Flight 610 and Ethiopian Airlines Flight 302. Netflix frames the film around the allegation that putting profit ahead of safety helped bring about the disasters. Its title signals its approach: this is an accountability story, not a neutral engineering lecture. Netflix’s description and credits make that framing explicit.

The documentary draws on aviation specialists, journalists, former Boeing employees, politicians and victims’ families. It turns a complicated aircraft-design and certification crisis into a comprehensible human story. That is its strength—and a reason to watch its claims with attention to who is speaking and what kind of evidence supports each point.

The 737 MAX was a more fuel-efficient derivative of Boeing’s established 737 rather than an entirely new aircraft. Its larger engines changed aspects of the aircraft’s aerodynamics. MCAS, short for Maneuvering Characteristics Augmentation System, was a flight-control function intended to improve handling in certain conditions, including at elevated angles of attack.
#1 Best Overall
Angle of attack is the angle between a wing and the airflow it meets. MCAS used angle-of-attack sensor data and could move the tail’s horizontal stabilizer to push the aircraft’s nose down. It was not an autopilot; it was a narrower automated function within a plane that pilots continued to fly.
The vulnerability was that the original system could respond to erroneous information from a single angle-of-attack sensor. In both crash sequences, bad sensor data contributed to repeated MCAS commands. A nose-down command is not inherently dangerous in every circumstance, but repeated commands amid warnings and other cockpit demands left crews facing a high-workload emergency. Boeing’s MAX materials describe the system and the changes the company proposed after the crashes.
That explanation is not a complete account of either accident. Sensor and software behavior interacted with cockpit alerts, pilots’ available information and training, maintenance history, certification assumptions and operational conditions. “Bad software caused the crashes” is too simple; MCAS was a central part of a wider chain.

Two crashes, five months apart
Lion Air Flight 610, a 737 MAX 8, crashed on October 29, 2018. Ethiopian Airlines Flight 302, also a 737 MAX 8, crashed on March 10, 2019. Together, the crashes killed 346 people. Investigators found important similarities in the role of erroneous angle-of-attack data and MCAS, while each accident also had its own circumstances and contributing factors.
The second crash turned the first into a global crisis. Authorities grounded the MAX, and scrutiny widened from the system itself to Boeing’s decisions, pilot training and disclosures, and the way regulators certified and oversaw the aircraft. Boeing acknowledged in 2019 that repeated MCAS activation in response to erroneous sensor signals featured in the accidents; its statements are useful evidence of the company’s position at the time, but are not a substitute for independent investigation. See Boeing’s congressional testimony and its response to the Ethiopian preliminary report.
Why the technology story is also a corporate story
Downfall connects MCAS to the MAX’s commercial context. Boeing was competing with Airbus and sought to update a familiar aircraft rather than replace it with a clean-sheet design. Commonality with earlier 737s had practical and commercial value for airlines, including the prospect of avoiding more extensive pilot training. Those considerations help explain the setting in which the design was developed; they do not, on their own, prove that any one executive decision caused either crash.
Rank #3
The film’s broader case is that engineering choices, disclosure and oversight were shaped by institutional priorities. It presents Boeing’s culture and cost pressures as part of the story, not merely background. That interpretation is plausible and consequential, but claims about motive—such as that profit was deliberately placed above safety—should be understood as the documentary’s argument and attributed to the people and records it presents, rather than treated as a technical finding by itself.

This is why “tech tragedy” is useful but incomplete. The technology depended on sensor inputs and software assumptions. Pilots needed enough information and training to understand the system and respond to failures. Certification determined what risks were assessed and how oversight worked. Company decisions influenced the design and what was communicated. An automated function became part of a human and institutional system—and that entire system matters to the explanation.
What the film does well—and what it compresses
The film makes a difficult technical story legible without reducing it to jargon. Interviews, archival news and hearing footage establish a chronology, while family testimony keeps the victims in view. The emotional force is appropriate to the scale of the loss, and the film is effective at showing why questions about manuals, training and certification are not bureaucratic footnotes.
Its prosecutorial structure also means it is selective. A feature documentary has limited time to distinguish accident findings, corporate statements, interviewees’ interpretations and disputed questions of responsibility. That compression can make institutional accountability feel cleaner than it is. Boeing, the Federal Aviation Administration, airlines, maintenance practices and pilots do not have interchangeable responsibilities, and a robust account should not collapse them into one villain or one failure.
Nor is the question of what pilots knew as simple as “they were told nothing.” In 2023, the National Transportation Safety Board said parts of Ethiopia’s final report were unsupported or misleading, including claims concerning electrical problems and the absence of MCAS documentation. The NTSB noted that Boeing had provided information to operators four months before the Ethiopian crash. That does not settle whether the information was sufficiently prominent or conveyed a full understanding of MCAS’s behavior and failure modes; it does make the distinction between no information and inadequate information essential. The NTSB’s comments on the Ethiopian report are a valuable counterpoint.
Boeing later said it would revise MCAS so the system compared data from both angle-of-attack sensors, activated only once in response to erroneous data, and operated under a maximum command limit while remaining overrideable by pilots. It also described changes to manuals and training. These are the company’s stated changes, not proof on their own that every organizational or oversight problem was resolved. The FAA published a summary of its review of the MAX’s return to service; it is useful alongside, rather than in place of, the film.

How to watch Downfall critically
- Separate the accident sequence—sensor data, MCAS commands and cockpit workload—from the film’s broader claims about corporate culture and motive.
- Notice whether a point comes from an investigator, a company statement, a former employee or a family member. Each brings a different kind of evidence and perspective.
- When the film makes a disputed claim, compare it with primary material such as the FAA’s review and the NTSB’s comments on the Ethiopian report.
- Keep the human cost central without confusing emotional testimony, however important, with independent proof of technical causation.
The film’s U.S. Netflix listing identifies it as a 2022 documentary, but streaming availability and catalog details can vary by country and date. Check the Netflix title page for the current listing in your region.
Verdict
Downfall succeeds as a gripping introduction to the 737 MAX crisis and a persuasive account of why engineering cannot be separated from the institutions that design, certify and explain it. Its weakness is compression, not a reason to dismiss its central concern: the crashes were not simply a story of software gone wrong. They were a human tragedy shaped by technical and organizational decisions—and the documentary is most valuable when viewers treat its indictment as a starting point for examining the evidence.
