Question: What did a  gunner of the "the Defender of London  win in World War I?

Air Chief Marshal Sir Keith Rodney Park, (15 June 1892 – 6 February 1975) was a New Zealand soldier, First World War flying ace and Second World War Royal Air Force commander.  He was in operational command during two of the most significant air battles in the European theatre in the Second World War, helping to win the Battle of Britain and the Battle of Malta.  In Germany, he was supposedly known as "the Defender of London". <SEP> The Hannover CL.II was an escort fighter, produced in Germany during World War I, designed in response to a 1917 requirement by the "Idflieg" for such a machine to protect reconnaissance aircraft over enemy territory.  It was a compact biplane of largely conventional configuration with single-bay staggered wings of unequal span.  The fuselage was a thin plywood paneled, wooden monocoque design, very similar to the style of fuselage in Robert Thelen's Albatros series of single-seat fighters.  The main units of the fixed tailskid undercarriage were linked by a cross-axle, and the pilot and tail gunner sat in tandem, open cockpits, with the gunner's cockpit elevated above the line of the upper fuselage to afford him a greater field of fire.  For the same purpose, the aircraft featured an unusually compact empennage, with a short fin integral with the rear fuselage structure and a biplane tail unit that allowed the rear gunner to have a larger field of aftwards fire when defending the aircraft.  Smaller than the usual C-class reconnaissance aircraft, it was easy for enemy pilots to mistake it for a single-seat fighter; a mistake that would bring them into the line of fire of the rear-facing dorsal gunner when closing from astern. <SEP> The Boeing B-29 Superfortress is a four-engine propeller-driven heavy bomber designed by Boeing, which was flown primarily by the United States during World War II and the Korean War.  It was one of the largest aircraft operational during World War II and featured state of the art technology.  Including design and production, it was the single most expensive weapons project undertaken by the United States in World War II, exceeding the cost of the Manhattan Project by between $1 and 1.7 billion.  Innovations introduced included a pressurized cabin, dual-wheeled, tricycle landing gear, and an analog computer-controlled fire-control system that directed four remote machine gun turrets that could be operated by a single gunner and a fire-control officer.  A manned tail gun installation was semi-remote.  The name "Superfortress" continued the pattern Boeing started with its well-known predecessor, the B-17 Flying Fortress.  Designed for the high-altitude strategic bomber role, the B-29 also excelled in low-altitude nighttime incendiary bombing missions.  One of the B-29's final roles during World War II was carrying out the atomic bomb attacks on Hiroshima and Nagasaki. <SEP> Second Lieutenant Arthur Rex Hurden Noss {'1': ", '2': ", '3': ", '4': "} (22 January 1897 – 15 September 1917) was a British World War I flying ace credited with nine aerial victories.  He won a Military Cross as Keith Park's gunner, and was killed in a flying accident shortly thereafter.
