Teacher: Now, understand the problem? Solve this instance: Question: What type of car did Wilson Fittipadli use at the Belgium race? Passage 1:RAF Mildenhall opened on 16 October 1934. King George V reviewed 350 aircraft there in 1935 on the occasion of his Silver Jubilee. This historical event is commemorated by a memorial tablet located in front of the Building 562, the current 100 ARW headquarters. During World War II, Mildenhall became a bomber station, flying Vickers Wellingtons, Short Stirlings and Avro Lancasters. It was also the headquarters of 3 Group Bomber Command. From 1950, Mildenhall became home to bombers and later tanker aircraft of the United States Air Force. Throughout the 1950s, Strategic Air Command bomber units were deployed on a regular rotational basis from the United States to the United Kingdom. The B-47 Stratojet was a familiar sight in the skies over RAF Mildenhall and RAF Upper Heyford at this time, as entire wings deployed on 90-day rotations. From 1976 to 1990, the SR-71 Blackbird was flown out of Mildenhall by Detachment 4 of the 9th Strategic Reconnaissance Wing of the USAF. RAF Mildenhall was, until 2003, the home of the largest military-sponsored air show in Europe, when it was cancelled because of increasing operational requirements.
 Passage 2:Brabham replaced Schenken with Argentinian Carlos Reutemann for 1972. Hill remained with the team, but Brabham put the Argentinian in the BT34. The 1972 Argentine Grand Prix saw Reutemann take pole in his first grand prix but finish seventh. The Argentinian retired from South Africa with fuel system failure. Reutemann broke his ankle after a mechanical failure on his Rondel Racing entered Brabham at Thruxton during a Formula Two race. The BT34 was not used at the Spanish and Monaco Grands Prix. For Belgium, Brabham entered a third car for Brazilian Wilson Fittipaldi, but he retired with a broken gearbox. The Brazilian finished eighth at the French Grand Prix. Fittipaldi finished 12th at Britain despite having stopped the car on lap 69 with broken suspension. The Brazilian finished seventh at the German Grand Prix. Fittipaldi retired from the final four races of the year, brake failure at Austria, broken suspension in Italy, broken gearbox at Canada and engine failure at the United States.
 Passage 3:In July 1952, Loring transferred to the 36th Fighter-Bomber Squadron full-time, where he served as operations officer. In this role he returned to combat duty, this time as a jet aircraft fighter pilot operating the F-80 Shooting Star. Missions for this unit primarily concerned close air support, air strikes and interdiction missions supporting United Nations Command ground troops in the country. In this role, Loring's unit primarily fought North Korean and Chinese ground targets. By November 22, 1952, Loring had completed 50 combat missions. At that time the ground battle in Korea had developed into a stalemate, with the two sides firmly entrenched along the 38th Parallel. Throughout November, the UN forces had been launching Operation Showdown against two targets: Triangle Hill and Sniper Ridge, northwest of Kunwha, north of the 38th Parallel. During the battle, the Chinese managed to amass 133 large caliber guns, 24 BM-13 rocket launchers and 47 anti-aircraft guns in the largest Chinese artillery operation during the Korean War, and it posed a serious threat to ground troops of the ROK 2nd Infantry Division operating in the area. The artillery was heavily guarded, forcing the UN forces to use airpower to combat them.
