Black Box (2020) Timeline Explained – Every Event in Order

Mathieu initially concluded it was a terrorist attack because the cockpit voice recorder revealed the sound of someone forcing entry into the cockpit shortly before the crash. This evidence, combined with the dramatic nature of a plane crash, led him to present this theory at a press conference before deeper analysis could be completed.

Foreshadowing: The early terrorist theory is later undermined when inconsistencies appear in the voice recorder.

Victor Pollock, Mathieu's supervising director at the BEA, disappeared during the investigation after being coerced by Xavier Renaud, head of Pegase Security. Pollock was forced to tamper with the voice recorder to conceal faults in Pegase's systems. He was later found dead, having recorded a confession before his death.

Foreshadowing: Pollock's disappearance drives Mathieu to investigate his house, where crucial evidence is eventually discovered.

Pegase Security designed the on-board aircraft communication systems for the Atrian 800. The company concealed known faults in the aircraft's rudder anti-stall system, which had unresolved issues despite receiving an air-worthiness certificate. When former employee David Keller attempted to expose these vulnerabilities by hacking the systems, the situation spiraled out of control, causing the crash.

Foreshadowing: A pilot informs Mathieu that the Atrian 800 had known rudder problems that were hidden from the public.

Noémie was suspended because Mathieu secretly downloaded flight data from her work computer at Atrian to run simulations for his investigation. When Atrian discovered the data loss, they held Noémie responsible, causing a severe strain on their marriage as she faced career consequences for Mathieu's obsessive pursuit of the truth.

Foreshadowing: The tension between Mathieu and Noémie reflects the personal cost of his investigation.

David Keller was a former Pegase Security employee who had previously been arrested for attempting to hack aircraft communications. He was aboard the doomed Atrian 800 flight. Rather than intending to cause a crash, Keller's goal was to expose vulnerabilities in Pegase's systems by taking control of the airplane's computer, but his hack spiraled out of control and neither he nor the pilots could regain control.

Foreshadowing: An investigative journalist reveals Keller's identity and his history with Pegase.

The Atrian 800 crash was not a terrorist attack but a technological disaster. David Keller hacked into the aircraft's computer systems to demonstrate security flaws in Pegase's design. However, the hack caused a loss of control that neither Keller nor the pilots could reverse, resulting in the plane crashing over the French Alps.

Foreshadowing: Mathieu discovers the original voice recorder in a pond behind Pollock's house, revealing the true sequence of events.

• crash cause
• loss of control
• system hack
• technological failure
• pilot inability

Pollock confessed that he tampered with the cockpit voice recorder under duress. Xavier Renaud blackmailed him, forcing him to conceal faults in Pegase's systems to protect the company's reputation and certification. Pollock's video confession revealed the extent of the coercion and the institutional corruption surrounding the investigation.

Foreshadowing: Mathieu finds the confession video in Pollock's house as danger approaches.

• pollock confession
• tampered voice recorder
• blackmail
• renaud
• corruption

Mathieu died in a car crash that was deliberately caused by hacking the vehicle's controls, mirroring the loss of control that occurred on the Atrian 800. As he fled Pollock's house after receiving the confession video, two mysterious figures arrived, and shortly after, his car veered off the road and crashed, killing him.

Foreshadowing: The car hacking mirrors the plane crash, symbolizing the systemic vulnerability Mathieu uncovered.

Noémie integrated Pollock's video confession into the Paris Air Show's audio-visual presentation system. When the confession played during the event, industry leaders and journalists witnessed the shocking reality of the cover-up. The public and media response was immediate, leading to Renaud's arrest and exposing Pegase's practices.

Foreshadowing: Noémie's act ensures the truth reaches a global audience despite Mathieu's death.

• noémie
• public exposure
• renaud arrest
• confession broadcast

The cover-up involved concealing known faults in the Atrian 800's rudder anti-stall system that should have prevented the aircraft from receiving certification. Pegase Security, facing potential liability and reputational damage, coerced BEA official Victor Pollock into tampering with evidence. When David Keller attempted to expose these vulnerabilities through a controlled hack, it accidentally caused the crash. The entire truth was concealed to protect corporate interests until Mathieu's investigation and Noémie's final act exposed it.

Foreshadowing: The conspiracy spans from the aircraft's certification to the manipulation of the investigation itself.

• cover-up
• corporate corruption
• certification fraud
• pegase
• bea investigation
