The Junkers Ju 87 Stuka entered service in the mid-1930s and became infamous during the early years of World War II for its steep precision dives. Its Jericho Trumpets were small propeller-driven sirens fitted to the landing gear legs, spinning faster as airspeed rose and producing the signature scream purely to terrify people below. After the war, recordings and recreations of that dive were reused in films, documentaries, cartoons and war games whenever a plane fell from the sky, turning the sound into a universal shorthand for an incoming aerial attack.
