Midland Army Air Field was home to the Army Air Forces Bombardier School, one of a dozen bombardier-training schools. It was one of the "West Texas Bombardier Quadrangle" schools of the Army Air Forces Training Command, along with Childress Army Airfield, San Angelo Army Airfield and Big Spring Army Airfield. The sole purpose of the Bombardier College was to train young men to use the Norden bombsight.
