Hi,

There turned out to be a problem in the documentation about sound 
positioning and orientation that is fixed now. This affects probably 
most aircraft that are available (which is very unfortunate) but the 
sound must have been wrong all along.

One thing was that inner-cone and outer-cone have been replaced by 
inner-angle and outer-angle at some point which just turned of sound 
orientation (the default values for them are to emit sound to every 
direction).

The direction have been updated in CVS for the following aircraft:
f-14b
B-2
SeaVixen
SR71-BlackBird
Lightning

Another problem was the sound position which were described +Y = left, 
-Y = right, -Z = down, +Z = up, -X = forward, +X = aft, but in reality are:

   +Z = left, -Z = right
   +X = down, -X = up
   +Y = forward, -Y = aft.

So to convert the old values to the new ones you should consider:

  new  old
   X = -Z
   Y = -X
   Z = Y
