By an act of Congress on October 1, 1942, during Olds' second class year, the academy began a three-year curriculum for the duration of the war for cadets entering after July 1939. Cadets applying to the Air Corps were classified as Air Cadets, with a modified curriculum that provided flying training but eliminated Military Topography and Graphics required for Ground Cadets. Olds' class was given an abridged second class course of study until January 19, 1943, when it began an abridged first class course.
