RE: screaming siren
What would be important to me would be to find an accurate sound. I heard all of these offerings on youtube and such and thye just did not sound realistic. I guess the first place to start is to track down exactly what they sounded like and work from there. I have heard that the sirens were essentially an air raid siren mounted in the spat. Not sure though. Certainly would be a market for this with all of the Stukas about.
