Hi Hakan I think the most recent example may have been "Enemy at the Gates", very effective. And Guernica the most infamous example. A similar technique was used by the South Africans in their bush war in Angola to cause panic. They had a lot of old Harvard trainers (North American T6 Texan), no sirens, but really noisy things - having a couple of Harvards going overhead at low altitude was like being hit by a club. I'm sure you're right about the Germans deliberately making the V1 noisy. Londoners heard it coming, then the engine would cut out - where would it land? The V2s were different - no warning at all, just the explosion. Even more terrifying. Anyway, great, no sinister ramjets in Swedish domestic boiler rooms, nor Stukas I'm sure.
