Air Intelligence Information Report — Unidentified Flying Objects, Tachikawa, Honshu, Japan, 23 January 1953

This document is an Air Intelligence Information Report regarding an unidentified flying object sighting that occurred on 23 January 1953 at Tachikawa Air Base, Honshu, Japan. The report details an observation made by two members of the Headquarters Squadron Section, whose names are redacted. At approximately 1745 hours, the witnesses observed a round object in the sky, which they described as changing color from red to blue-green and finally to white. The object was observed for no more than two seconds as it traveled downward at a 70-degree angle. The witnesses reported that the object left a trail more than ten times its diameter in length. The witnesses attempted to estimate the size of the object, comparing it to a basketball, and suggested the trail was half a mile long, though the reporting officer, Captain Davis B. Potter, noted that these estimates were unreliable due to the lack of a reference point. The report concludes that the object was likely a meteor. An additional assessment provided by the Director of Requirements, Colonel George D. Hastings, mentions that while Air Weather Service personnel suggested that radiosonde balloons in high winds could produce a similar visual effect, no such balloons were launched from Haneda Air Base in the Tokyo area at the time of the sighting. The document is marked as unclassified and includes instructions for periodic downgrading and eventual declassification.
