Project Blue Book Case File
In the sea Off coast of Taichung, Taiwan, March 1958March 1958
Summary
In March 1958, fishermen off the coast of Taichung, Taiwan found an unidentified object in the sea and handed it over to the Chinese Nationalist Air Force. The object was then loaned to the American Embassy in Taipei for identification purposes. The Air Force's evaluation of the object remains unclear in the available documents.
The file includes seven photographs of the object, along with a descriptive drawing showing its various components made of materials including black soft rubber, milk-white plastic, transparent plastic, and aluminum alloy. However, the heavily degraded OCR text on the analysis pages makes it impossible to extract specific details about the object's appearance, construction, or the findings of the technical review.
Later analysis notes in the file suggest that personnel who examined the object could not reach a clear consensus about its identity or purpose. The file indicates that additional background information might have been useful to the investigation. An Air Force evaluation form on the first page lists "Probably Balloon" as the conclusion, though the basis for this determination is not legible in the remaining case materials.
The full case file is reproduced below as held by the National Archives, comprising 8 pages.
