There were actually four microphones - captain, first officer, cockpit and observer (see page 46, Figure 9). Four receivers is sufficient to determine the sound origin at a point in space, with an associated error volume (three receivers only allows you to determine a curve in space).

The problem is complicated if we consider that the missile is moving at supersonic speeds (~mach 3 + aircraft speed). I don't know much about supersonic fluids. For anyone interested in following this up, here is a paper on "Reproduction of Virtual Sound Sources Moving at Supersonic Speeds in Wave Field Synthesis": http://www.researchgate.net/publication/230702229 http://www.researchgate.net/publication/230702229
