Unidentified Flying Objects near McClellan AFB, California

This document is an Air Intelligence Information Report (IR-186-52) dated 21 April 1952, concerning a sighting of unidentified flying objects near McClellan Air Force Base in California. The report details an incident that occurred on 20 April 1952 at 2133 PST. A commercial pilot, identified as Mr. Fidalli, reported observing seven to ten luminous objects from a ground position. According to the report, these objects appeared to follow an aircraft that was landing at the base. The duration of the sighting was estimated at three to five seconds, with the objects moving in a north-northeasterly direction at an altitude of 1,000 feet or less. The report notes that there was no unusual sound associated with the objects. The document includes a Project 10073 record card, which summarizes the incident and categorizes the conclusion as 'Insufficient Data for Evaluation.' The report was prepared by Captain Charles J. Powley and approved by Colonel William L. Travis of the Intelligence Division, HQ MATS. Additionally, the file contains a separate, unrelated brief report (ATI 193667) regarding a sighting of four glowing spheres over Almansa, Spain, on 21 April 1952, which were described as changing color from reddish to intense yellow. The primary document regarding the McClellan AFB incident emphasizes the lack of sufficient information to draw a formal conclusion, reflecting the standard intelligence assessment process for UAP reports during this period.
