In August 1943, Kirtland Field became host to a USAAF Provisional B-24 Liberator Pilot Transition School designed to train airplane commanders. Transition training was the final step after successful completion of Primary, Basic, and Advanced Flying training. The Bombardier School, for the most part, furnished facilities and maintenance, and personnel from two squadrons, that had been part of the Bombardier School, were put to work in the B-24 school. Officer pilots were selected for the new school from advanced twin-engine training schools. Instruction covered day and night navigation and instrument flying, formation and altitude flying, comprehensive ground schoolwork, engineering, radio, meteorology, weather flying, first aid and oxygen training, as well as a course on the duties of an airplane commander.
