Well (again), this is my frustration speaking but I can't really see how I can kill that nasty SR-71! If the SR-71 didn't have ECM (or at least a so powerfull one) I think there would be some chance to shoot one SR-71 down.
What kind of SA complex you used? Volkhov got him pretty well... (I didn't try in 923.3, but untill now it was possible)
