Diving sound

[Terry]

As most of the old war movies use the same or similar sound for any diving or crashing plane, I suspect it's just the movie directors dubbing in stock sound for effect. The sound probably originated from an old biplane with lots of wires singing in the wind. Or perhaps the sound is faked to begin with.

In the early biplane Helldivers (Curtiss) the wind in the bracing wires was somewhat responsible. Indeed the STUKA's used a siren. I'll agree with a previous scrivner that the prop tips going supersonic may be a large contributor here. Listen to the windup sound of a Cessna 185 with a two blade seaplane prop takeoff and you get the idea.
