China PLAAF Baotou UAP Intercept 1981

On July 24, 1981, the People's Liberation Army Air Force's Baotou Air Defense District radar detected an unidentified contact at approximately 50,000 feet altitude over the strategically vital Baotou industrial region of Inner Mongolia — home to major steelworks and a concentration of the rare-earth mineral processing facilities critical to Chinese industry. PLAAF interceptors were scrambled but could not reach the contact's altitude with the available aircraft. The contact performed stationary hover followed by departure at extreme speed. PLAAF Air Defense Command issued a classified internal report. The existence of the incident became known through testimony from PLAAF veterans who spoke to researchers in the 1990s following Chinese political liberalization. The accounts were subsequently corroborated by US signals intelligence records noting anomalous Chinese military communications traffic indicating an air defense emergency on the date in question. The Baotou case is considered the most credible Cold War-era PLAAF UAP encounter on record.
