The Concorde, a supersonic passenger jet, was notorious for its immense noise levels, particularly during take-off and landing. Its turbojet engines generated a distinctive sonic boom when it exceeded the speed of sound, causing a loud, thunderous noise that could be heard miles away. The sheer volume of the engines’ roar, combined with the supersonic speed, made the Concorde a source of concern in terms of noise pollution, leading to restrictions on its flight paths over populated areas. While its speed and technology were groundbreaking, the noise it produced became one of the key factors in its eventual retirement.
