The not-so-mysterious world of Black Boxes

Updated: Sep 5

Before I begin, my heart goes out to those who lost their loved ones last month in the terrible crash in India.


A few days in and the internet was abuzz with information around the plane's Black Box' - so what is it?


Despite the name, a plane’s “black box” isn’t black at all — it’s bright orange. Why? So it can be spotted more easily in wreckage. And that’s just the start of its fascinating story.

Every commercial jet carries two of them: the Cockpit Voice Recorder (CVR) and the Flight Data Recorder (FDR). Together, they capture hours of cockpit conversations, sounds, and thousands of performance parameters like altitude, speed, and engine power.

Black boxes are tough. Really tough. They’re designed to survive crashes, explosions, fire, and being submerged in the ocean for weeks. Think of them as the ultimate “save file” for flights.


The idea dates back to the 1950s when Australian scientist Dr. David Warren invented the first version. Today, thanks to his work, investigators can reconstruct the final minutes of almost any incident, helping prevent future accidents.

Interestingly, some experts now argue for “live streaming” flight data via satellite instead of relying solely on recoverable boxes. But until that’s universal, the trusty black box remains the unsung hero of aviation safety.


Next time you fly, know this: your journey is not only guided by pilots and technology — it’s being carefully recorded, just in case the skies have lessons to teach.
