Centex AT-6, SNJ, "Harvard", and the L-5, served U.S. in wars and later used by the World's Air Forces.

The AT-6 Texan successfully trained thousands pilots in WWII and was subsequently used by many of the World's Air Forces. Later, the Chinese CJ-6A Trainer becomes a favorite of Communist Bloc Air Forces.
The story of the North American Aviation's T-6 Texan.
(Navy - SNJ, Internationally - the Harvard)



The North American Aviation "T-6 Texan" was a single-engine advanced trainer aircraft used to train pilots of the United States Army Air ForcesUnited States NavyRoyal Air Force and other air forces of the British Commonwealth during World War II and into the 1950s. Designed by North American Aviation, the T-6 is known by a variety of designations depending on the model and operating air force. The USAAC and USAAF designated it as the AT-6, the United States Navy the SNJ, and British Commonwealth air forces, the "Harvard", the name it is best known by outside of the US. After 1962, US forces designated it the T-6. It remains a popular warbird aircraft used for airshow demonstrations and static displays.

This was the first time that a Syrian aircraft had shot down an enemy plane in combat. Six days later this same T-6 was brought down by Israeli ground-fire.

Centex's own L-5 actually served in several wars as a trainer, spotter and in battlefield evacuations.
Centex's L-5 actually saw action in Saipan, Okinawa and Korea.
Stinson L-5 Sentinel
The Stinson L-5 Sentinel was a World War II era liaison aircraft used by all branches of the U.S. military and by the British Royal Air Force. Along with the Stinson L-1 Vigilant, the L-5 was the only other American liaison aircraft of World War II that was purpose-built for military use and had no civilian counterpart. All other military liaison airplanes adopted during World War II were lightly modified "off-the-shelf" civilian models.
Capable of operating from short unimproved airstrips, the L-5 "Sentinel" delivered personnel, critical intelligence and needed supplies to the front line troops. On return flights, wounded soldiers were often evacuated to rear area field hospitals for medical treatment, providing a huge boost to the morale of combat troops fighting in remote areas. L-5's were used for many other important activities, such as aerial photography, controlling vehicle convoys, para-dropping food, medical supplies and ammunition, laying communication wire, distributing propaganda leaflets, spraying pesticide, transporting prisoners, and directing fighter-bombers to ground targets. The L-5 was also popular with Generals and other high-ranking officers for fast, efficient short-range transportation.
L-5 used for Medical Evacuation.
During the Battle of Okinawa, L-5 operated from an LST using the Brodie landing system which allowed a light aircraft to take off and land without a flat surface by snagging a wired hung between two booms. One of the L-5 that used the Brodie system off Okinawa is now on display at the Smithsonian Institution Aerospace Museum in Washington, DC.
Our CJ-6, a Chinese trainer is now a favorite in many Air Forces.
Nanchang CJ-6

The Nanchang CJ-6 is an aircraft designed and built in China for use by the People's Liberation Army Air Force (PLAAF) as a basic trainer.
The Chinese engine certainly has its idiosyncrasies.
The CJ-6 (translation 初教 or CJ = 级教练机 or Chuji Jiaolianji = Primary Trainer in English) is an all-original Chinese design that is commonly mistaken for a Yak 18A. Its predecessor, the Nanchang CJ-5, was a licence-built version of the Yak-18. However, advancements in pilot training brought a need for a new aircraft with improved performance and a tricycle landing gear. When the Soviet Union developed the Yak-18A, PLAAF engineers decided that its performance and design would not suit China's needs. A few important Chinese aircraft designers were involved in design task of CJ-6, Lin Jiahua (Nanchang 320 Aircraft Factory designer, previously involved in CJ5's design project), Xu Xunshou (key member of J-7/J-8 fighter jet design team in 1970s) and Zhiqian Huang (Chief designer of J-8 fighter jet).

One thing to note is that the Nanchang CJ-6 makes extensive use of pneumatics to control the gear and flap extension/retraction, operate the brakes and start the engine. An engine-driven air pump recharges the system, however if air pressure is too low to start the engine then the onboard air tank can be recharged by an external source. If an external source is not available then the engine can be started by hand swinging the propeller.
Civilian Use
Due to its inexpensive price and sturdy construction, the CJ-6A is a popular hobby plane. A used CJ-6 in the United States can cost as little as $75,000. The aircraft appears on the civil register of the USA, Australia, UK, South Africa and other countries.
