P-51D GUNNERY PRACTICE In early June, 1944, the Eighth Air Force began to receive a new variant of the P-51: the D version. Although pilots really loved the Mustang, they complained about the limited rear visibility. North American fitted a teardrop canopy onto the P-51, which allowed for 360-degree visibility. Other improvements to the P-51 included the addition of one more .50 caliber machine gun in each wing, bringing the total firepower to six guns. The P-51D was built in greater numbers than any other Mustang, with 7,956 produced. YOUR MISSION Flying over the coast of southwestern Holland, you encounter three different pairs of fighters on patrol. The enemy planes will not evade your attack, but you'll have plenty of opportunities for deflection shooting. To be accurate in a deflection shot, you must lead your target so that your bullets intercept its line of flight. Your P-51D cannot be damaged and has unlimited ammunition. Your mission will not end automatically. You must choose to quit. Please see your reference guide for instruction on how to quit, as well as information on other controls.
