In the Pre-Flight School, the navigation cadet recieved nine weeks of
intensive physical and mental conditioning for the arduous fifteen-week course
which confronted him in the Advanced Navigation School.
In class, he was instructed in Morse Code, meteorology, mathematics, physics,
naval forces, organization of the Army Air Forces, aircraft identification,
and basic military science.
The military science was carried out onto the drill field, where daily he
studied close order drill by doing it. He recieved instruction in voice and
command, uniform and insignia, discipline and military conduct. And then he
marched some more.
Physical conditioning recieved great emphasis. By a series of graduated
exercises the cadet was brought to a peak of condition. Corrective calisthenics
were introduced when indicated.
The calisthenics prescribed were the result of a special study with regard to
the requirements of an air navigator. The exercises were devised by physical
directors and physicians who observed a naked man performing the duties of a
navigator while in flight. From this research it was possible to determine
what muscles and reactions come into play. Special exercises embodying these
conditions were used.
In every stage of his training, the navigation cadet was under the tutelage of
experts in their fields.
The cadets were organized into squadrons. Cadet officers commanded the squadrons
and higher units, under the supervision of tactical officers of the staff of the
Pre-Flight School.
