History: With retractable landing gear
and a powerful engine, the Vultee V-54 basic combat trainer was too lavish for the
cash-strapped United States Army Air Corps of 1938. So Vultee redesigned the aircraft and
made it less complicated. The first order for 300 new BT-13 Valiants
was placed in September of 1939, and it would become the most widely-used American
training aircraft of World War Two.
The Vultee BT-13 had a continuous canopy with its crew of two sitting in tandem behind
dual controls. It was also equipped with blind flying instruments to teach new pilots the
basics of flying at night or in foul weather. BT-13 students soon gave the airplane a
nickname which described its most memorable characteristic: Vultee Vibrator.
The only major variant of the BT-13 was the BT-13B,
which featured a revised electrical system. Because of the speed with which the BT-13s
were built, there was soon a shortage of Pratt & Whitney Wasp Junior engines. To
overcome the shortage and maintain production levels, the BT-15,
using a Wright Whirlwind engine, was then introduced. Two thousand BT-13s and BT-13Bs were
transferred to the US Navy, where they were designated the SNV-1
When production ceased in 1944, 11,537 Valiants had been produced. The Valiant was retired
at the end of the war, but over 100 of these aircraft are still registered in the United
States today, although it is believed that less than half are actively airworthy. [History by David MacGillivray]

This is the final video starring noted aviation historian and pilot Jeff Ethell. It
features him flying the T-6, BT-13 and the PT-22. This video is a unique look at the
aircraft which taught thousands of young men to fly in World War II, presented as only Mr.
Ethell could do it.
