In the final episode, the people closest to the Concorde project – from the teams who engineered its first flight to those who picked up the debris after the fatal Air France crash – tackle the biggest question: Why did Concorde disappear from our skies?

We also discuss Concorde’s legacy and its impact on the aviation sector, on travel itself, and on the personal and professional lives of those who built the plane. And before they turn off their mics for the season, host Nastaran Tavakoli-Far and lead producer Pedro Mendes, alongside aviation journalist Eric Tegler, take a closer look at some recent projects that promise to fly us faster than the speed of sound – again.
