This documentary investigates the build-up to two tragic Boeing plane crashes in a chilling exposé of U.S. corporate culture, greed, and complacency.

Most of us consider flying a safe and convenient method of travel.

Statistically, the last few years of the 2010s were the safest in the history of aviation, with airplanes becoming increasingly common and sophisticated.

At the heart of this industry-wide success story was Boeing, a towering figure in the aviation industry with a proud safety record.

Then, in the space of a few months, two of the company's planes crashed.

In Downfall: The Case Against Boeing, director Rory Kennedy examines the two tragedies in detail and exposes the preventable mistakes which led to them.

Kennedy's film portrays Boeing as a company contaminated by greed, prioritizing profits over the safety of its passengers.
