During the Second World War, the United States Army Air Forces used a
three-phase training program for pilots, Primary, Basic and Advanced. With each
phase, aircraft complexity and the difficulty of the tasks to be mastered
increased. At the end of Primary, cadets, now capable of performing simple
flight requirements left behind the open-cockpit, fabric and wood PT-13, PT-17
& PT-19 training aircraft and moved up to the more complex challenges of

introduce fledgling pilots to basic flight maneuvers. During the war, over
11,500 BT-13As and its variants were produced.

The museum's BT-13A, s/n 41-21487, was manufactured by Vultee Aircraft Inc.,
