T-37 Tweet

A T-37 Tweet aircraft from the 85th Fighter Training Squadron, Laughlin AFB, Texas, flies over Lake Amistad during a training mission. The T-37 Tweet is a twin-engine jet used for training undergraduate pilots, undergraduate navigator and tactical navigator students in fundamentals of aircraft handling, and instrument, formation and night flying. The twin engines and flying characteristics of the T-37 give student pilots the feel for handling the larger, faster T-38 Talon or T-1A Jayhawk later in the undergraduate pilot training course. The instructor and student sit side by side for more effective training. The cockpit has dual controls, ejection seats and a clamshell-type canopy that can be jettisoned.
