T-34 Mentor
The T-34A was used by the USAF for primary flight training during the 1950s. The original Mentor, a Beechcraft model 45 derived from the famous Beechcraft Bonanza, was first flown in December 1948.
The first military prototype made its initial flight in May 1950. After extensive testing, the USAF ordered the Mentor into production, with the first production T-34A delivered to Edwards AFB in October 1953 for evaluation.
