Schweizer SGS 2-33/ TG-4A Training Glider

Schweizer SGS 2-33/ TG-4A Training Glider

Gliders were the first winged vehicles to take humans aloft, and today tens of thousands of pilots enjoy the challenge of flying without engine power. Glider pilots become adept at reading the invisible behavior of the air they fly through. Combined with careful management of energy and speed, they stay aloft without engine power for hours at a time. Ernest Schweizer designed the 2-33 in 1965, and it soon became the most widely used training glider in North America. Schweizer made 579 of them between 1967 and 1981, and hundreds are still flying. The US Air Force purchased 13 of them for use at the Air Force Academy, giving them the military designation TG-4A. From 1970 to 2002, these gliders were a common sight over the Academy.
