Argus
            Motorengesellschaft is most famous for its inverted vee piston
            engines, notably the As 10 inverted V-8 and the As 410 inverted V-12
            which powered the Fw 189 and Ar 96.  Perhaps their most
            notorious engine was the Argus-Schmidt 109-014 pulsejet used to
            power the V-1 buzz bomb.
