text: The machine guns mounted on the side of the landing gear sponsons were mock-ups that used spark plugs and fuel to simulate gun firing. Other modifications were implied with Foley and sets; the interior sets were of a fantastical high-tech nature, and there were implied "stealth" noise-reducing capabilities with creative use of sound effects. On the show, the deployment of the weapons systems were usually shown via close-ups of the action; in reality, these close-ups were produced on props off-site, while the non-moving prop components were attached to the aircraft by a technician in the field or at the JetCopters hangar.
  The concept behind Airwolf was a super-fast and armed helicopter that could "blend in" by appearing to be civilian and non-military in origin, a "wolf in sheep's clothing". Airwolf's insignia patch (also designed by Probert) as worn by the flight-crew was a snarling wolf's head with gossamer wings that appears to be wearing a sheepskin complete with the head of a lamb over the wolf's forehead. Airwolf is sometimes referred to in-show as "The Lady" by Santini and Hawke.
  In the show, Airwolf was an armored, stealthy aircraft. It could perform impossible maneuvers and stunts, including traveling at Mach speeds (the theoretical maximum speed of a helicopter is significantly below Mach 0.5, or half the speed of sound), and flying into the stratosphere. Some of these impossible capabilities are explained in the show by such features as auxiliary jet engines (visible at the roots of the landing gear sponsons), rotor blades that can be disengaged for supersonic flight and a lifting body fuselage.
