Shenyang JJ-1

The Shenyang JJ-1, also known as the Hong Zhuan-503 or Red Special, was a jet trainer developed in the People's Republic of China (PRC) during the 1950s.

To ensure that the People's Liberation Army Air Force could re-equip and train to fly jet fighters Shenyang Aircraft Corporation were approached by the PLAAF to design and build a prototype jet trainer.

Most team members were recent university graduates, and only three people: Xu, Huang, and Lu Xiaopeng, had any aircraft design experience.
