required to crawl down shafts that gave way to the "bubble," from which they had bird's-eye views of the ground below. The bombardier's job was to feed the bombsight the needed information, air speed, wind speed, wind direction, altitude, and the angle of drift. As the aircraft approached the target, the pilot turned the aircraft over to the bombardier and the Norden bombsight, which was also an automatic pilot that flew the aircraft as bombs were released over the target. Classroom instruction at the Albuquerque base was held at night and training missions were flown during the day to bombsights around Albuquerque. Servicemen and WPA workers were tasked with laying out bombing ranges for training. These were located west and southwest of Albuquerque, including a major range located between the neighboring village, Los Lunas and the Rio Puerco. Contracts for day and night bombing targets on the ranges were let during January 1942, and access roads to the targets were constructed. Bomb ranges numbered 2,450 square miles on ranch and Indian reservation land by the end of 1942. At that time, a total of 24 targets, simulated cities and warships, were in use on the ranges. Bombardier school was 12 to 18 weeks during which a student dropped approximately 160 bombs; precise records were kept of hits and misses. The elimination rate for trainees was 12 percent, and upon graduation, a new bombardier was transferred to an operational training unit and trained for overseas duty. Albuquerque was an operational training facility, and the first class of 61 bombardiers from the Albuquerque base school graduated 7 March 1942. By 1945, Albuquerque's flying training field had turned out 5,719 bombardiers and 1,750 regular pilots for the B-24 bomber alone. The 51st class to complete the bombardier training course included 143 bombardiers. Chiang Kai-shek pilots and bombardiers received training from Kirtland Field instructors. And film actor Jimmy Stewart was stationed at Kirtland Field briefly, beginning in August 1942, assisting bombardier cadet training by flying bombers on training missions. Additional training Bombardier and pilot training was not the only focus at Kirtland Field between 1942 and 1945. In 1943, the USAAF Flying Training Command merged with the Technical Training Command in an effort to save manpower. The new command, the Air Training Command, became responsible for all training from classification center through pilot and technical schools. In 1943, Kirtland Field facilities expanded to support
