Air Intelligence Information Report: Unidentified Flying Object Sighting, Saigon, Indo-China, 28 May 1952

This document is an Air Intelligence Information Report (IR-172-52) dated 14 June 1952, concerning an unidentified flying object sighting in Saigon, Indo-China, on 28 May 1952. The report, authored by Lt. Col. William H. Huntley Jr., details an incident where a white-silver, disk-shaped object was observed by multiple individuals, including prominent local business figures such as Mr. Reichauld and Mr. Desjardina, between 10:00 and 11:00 A.M. The witnesses described the object as brilliant, metallic, and moving in a perfectly straight line at high speed. One witness initially compared it to a weather balloon but rejected that conclusion due to the object's speed and movement. The report includes a summary of the sighting, a witness account, and a confirmation from the local Service Meteorologique that no weather balloons were released in the area at the time of the sighting. The reporting officer conducted an investigation, including personal contact with the witnesses, but was unable to locate additional observers or physical evidence. The report concludes that the object remains unidentified, noting that this was the first such report of a 'flying saucer' known to the office in Indo-China. The document includes a Project 10073 record card and provides specific coordinates for the observation point at the intersection of Rue Lefebvre and Rue George Guynemer. The report is marked as unclassified and includes instructions for downgrading and declassification under DOD Directive 5200.10.
