Project Blue Book Case #3341. On November 28, 1954, an unidentified aerial object was reported in the vicinity of Manila, Philippines. The Philippines hosted major American military installations including Clark Air Base — one of the largest U.S. Air Force bases outside the continental United States — and Subic Bay Naval Station, both critical to American power projection in the western Pacific.
Clark Air Base, located approximately 60 miles northwest of Manila, was the headquarters of the Thirteenth Air Force and a key staging base for operations throughout Southeast Asia and the Pacific. The base's fighter and reconnaissance squadrons maintained constant readiness against potential threats from Communist China and other regional adversaries.
The November 1954 timing placed this sighting during the tail end of the extraordinary global wave that had produced thousands of reports across Europe, particularly in France and Italy, during September and October. By late November, the wave had spread far beyond Europe, with reports coming from South America, Africa, and the Asia-Pacific region.
Manila's tropical setting and busy airspace — combining military operations from Clark and Subic Bay with commercial traffic through Manila International Airport — created a complex aerial environment. The reported object was distinguished from this normal traffic by characteristics that trained observers could not reconcile with any known aircraft type.
Investigation through Pacific Air Forces intelligence channels failed to identify the object. The case was classified "Unknown" by Blue Book.
