So we all used to watch those wonderful cartoons when we were younger and whenever a plane would fly by or go down you would hear that familiar shrieking plane sound. Well what we were actually hearing was this baby, the German Ju-87 Stuka dive bomber with its siren equipped, whenever it dove the sirens on its wings would emit a piercing shriek designed to terrify and demoralize those on the ground (They were often called "the Jericho trumpet"). I always found it funny that one of the most prolific icons of blitzkrieg is used in a child's cartoons haha. Here is what the siren actually looks like- [url]http://cdn-www.airliners.net/aviation-photos/photos/9/8/7/1154789.jpg[/url] You can see the little propellers above the landing gear, those are the sirens.
