Puss hears a Stuka

Puss in Boots tries to survive Dunkirk (2017). Sadly, the Luftwaffe enlisted a new highly skilled pilot with an extreme vendetta against Puss. Puss then hears one of the most horrifying sounds of World War 2. The “Death Whistle“ you hear here are the “Jericho Trumpets“ that were placed on the German Junkers Ju 87 or Stuka dive bombers. The sound was created by propeller-driven sirens mounted on the undercarriage legs of the plane. Its purpose was to damage enemy morale through psychological warfare and it was quite effective at doing so early in the war, giving the Stuka a terrifying reputation. Later in the war, however, it was found that the sirens decreased the speed of the plane by 20-25 km/h, leaving it vulnerable to AA fire and enemy fighters. The Germans also realized that the sirens ruined the element of surprise by giving Allied soldiers an early warning. For these reasons, the sirens were removed from later models of the Stuka.
