PROJECT 10073 RECORD CARD - SANGLEY POINT, PHILIPPINES

On August 28, 1963, at approximately 1330Z, personnel at Sangley Point, Philippines, including the Commanding Officer, observed 25 groups of 2-6 unidentified objects. The objects were described as tan-orange, round, and lacking a defined formation, exhibiting flickering tails. They were observed rising from the horizon, drifting on a course between 00 and 040 degrees at an estimated speed of 10-15 knots and an altitude ranging from 500 to 5,000 feet. The observation lasted for approximately one hour. The objects were tracked using a theodolite. Although photographs were attempted, the results were negative. Subsequent investigation by the 13th Air Force, which included reports from a Patrol Squadron Forty pilot who flew within 1,500 feet of the objects, determined that they were hot air balloons with lighted flares attached. These balloons were identified as having been launched as part of a festival in the barrio of Rosario, near Sangley Point. Following this positive identification, the 13th Air Force issued a local warning regarding the hazard to air navigation and closed the incident.
