Spook of St Trond
Heinz-Wolfgang Schnaufer was an incredibly successful night fighter with 121 victories, mostly against British four engined planes. Using a technological innovation of 20mm cannons on his Bf 110, mounted near vertically like organ pipes enabled him to shoot Allied craft from below.
The noise the cannons made sounded like Jazz drums to the German pilots and they nicknamed it Schraege Music. It was the sound of disaster for the allied crews and they nicknamed Schnaufer the Spook of St Trond.
