Taiwan Strait UAP Wave — CIA-Filed Chinese Nationalist Military Investigation

Beginning July 17, 1968, multiple unidentified flying objects were observed flying over the Taiwan Strait and the Republic of China-held offshore islands, including Kinmen (Quemoy) Island — the heavily fortified outpost that had been the site of intense cross-strait shelling just a decade earlier. The sightings were not isolated incidents: they occurred consistently on a daily basis for weeks, always within a predictable window of approximately 19:15 to 21:30 local time, and the objects flew predominantly from east to west.

臺灣海峽及金門地區出現的不明飛行物（UFO）現象在1968年7至8月間引起了中華民國軍方的高度重視。 The regularity and consistency of the sightings — same time window, same directional path, same appearance over multiple nights — prompted the Republic of China military to take the matter seriously rather than dismiss it as isolated misperception. A three-officer technical investigation team of Chinese Nationalist military officers was assembled, assisted by personnel stationed on Kinmen Island itself.

The team conducted a formal investigation over several weeks, collecting witness statements from military observers, civilian observers, and astronomical observatory workers across the region. Both military and civilian pilots reported encounters in the wider Taiwan Strait area. The investigation produced a classified report, which was filed through ROC military channels.

The CIA obtained a copy of this investigation. The document, CIA reference CIA-RDP81R00560R000100070028-5, was subsequently declassified and released through the CIA FOIA Reading Room. It is one of the few UAP-related documents in Chinese that has been formally processed by a US intelligence agency and made publicly available.

The investigating officers concluded that the objects were "probably man-made satellites" but explicitly acknowledged they could not rule out alternative explanations, including what the report terms "flying saucers," electronic jamming devices deployed by the People's Republic of China, or psychological warfare balloon systems. The equivocal conclusion reflects the genuine uncertainty of the investigation: objects that appeared daily on schedule, followed a consistent path, and were observed by both military and astronomical personnel across a broad area could not be explained by any single mundane cause the investigators could confirm.

The Taiwan Strait case is historically significant for several reasons. It demonstrates that the UAP phenomenon was not exclusively documented by Western militaries during the Cold War; it shows that Chinese Nationalist military authorities took the matter seriously enough to conduct a formal multi-officer investigation; and it provides a CIA-filed foreign government document that expands the geographic and cultural record of mid-twentieth-century UAP encounters beyond the predominantly American and European cases that dominate existing archives.
