I shot down a Piper Cherokee (VH-HSV) near Bendigo, Victoria, Austraila on my first try!

Haven't bought it yet (going to in a few minutes), but the site does say it works with any FSX plane or helicopter.  I kind of like the idea of a world where a Piper can shoot back!  In fact, maybe I'll use my Carenado PA-28-180 to score my first kill.

...and maybe I will have to modify the textures to include the message "Intercept this..." spray-painted on both sides.
