The Valiant, known as the the "Vibrator" by the pilots who flew it, was the basic trainer most widely used by the USAAF during WWII, representing the second of the three stages of pilot training - primary, basic and advanced. In all some 10,375 P&W engined BT-13s and Wright-engined BT-15s were built. This one was registered N62645 postwar and was obtained by the museum in 1965

The Valiant was the basic trainer most widely used by the USAAF during WWII, representing the 2nd of the 3 stages of pilot training; primary, basic and advanced. Compared with the primary trainers in use at the time, it was considerably more complex with a more powerful engine, so faster and heavier. In addition, it required the student pilot to use two-way radio comms and to operate landing flaps and a two-position variable pitch propeller. This example is on display at the National Museum of the USAF.
