This is a trademark flyover by the French Air Force’s aerial acrobatics team, the Patrouille de France.
A few years ago, they performed a creative aerial display to celebrate the 50th anniversary of one of France’s most beloved comic book characters: Astérix the Gaul. The chatter is in French, but even if you don’t speak the language, you should watch the payoff (the video is just three minutes long). Very cool.
