A polished silver colored version of these badges is currently used as the United States Air Force Pilot Badges. From August 1941 to November 1942, the Enlisted Aviator program was restarted. Candidates had to be at least 18, possess a high school diploma, and have graduated at the top of their high school class. Graduates were rated as Flight Staff Sergeants or Flight Technical Sergeants and wore the same pilot's wings as officers. They were usually assigned to pilots of transport and auxiliary aircraft to free officer pilots to pilot the more prestigious fighters and bombers.
Auxiliary pilots received their own special wings to indicate their status and specialty. In November 1942 all enlisted pilots were promoted to Flight Officer rank and enlisted cadets were graded as Flight Officers or Second Lieutenants depending on merit.
