Concorde was the Anglo-French supersonic passenger jet famous for crossing the Atlantic in under four hours, and its cockpit included a distinctive overspeed warning to alert pilots when the aircraft exceeded its certified speed limit. Aviation enthusiasts have shared cockpit recordings and simulator audio for years, and short clips like this one have become popular outside aviation circles too. Creators now reuse the alarm as shorthand for anything moving dangerously fast, from racing edits to reaction videos, because the urgent beeping is instantly understood even by viewers who have never flown on Concorde.
