Ever since the Concorde’s final landing in 2003, commercial air travel has been getting slower, not faster—despite decades of technological progress. The reason lies less in engineering limits than in economics and physics: supersonic flight creates disruptive sonic booms, guzzles fuel, and forces airlines onto narrow, unprofitable routes. In this episode, we explore why modern jets cruise below 900 kilometers per hour, how fuel efficiency and environmental costs now outweigh the lure of speed, and why passengers have quietly accepted longer journeys in exchange for cheaper tickets. Even as new designs promise quieter booms and cleaner fuels, the story asks whether the age of faster-than-sound travel will ever truly return—or whether convenience, not velocity, now defines the future of flight.
