UFOs Index Card — South Bay, California, 9 August 1955

This document consists of a UFO Index Card (AISS-UFOB-260-55) and an associated military teletype report regarding a sighting that occurred on 9 August 1955 in South Bay, California. The witness, a 12-year-old civilian, reported observing a single, silver, disc-shaped object for approximately 39 seconds. The witness described the object as being the size of a grapefruit held at arm's length and noted that it produced a sound similar to a jet engine. The object was observed traveling from west to east. The military investigation, conducted by the 751st ACWRON, concluded that the sighting was likely a conventional jet aircraft. The report explicitly notes that the observer's age limited their ability to identify the object correctly. The investigators reasoned that the sunlight reflecting off a conventional aircraft, combined with the noise, created the appearance of a disc-shaped object. The report also mentions heavy air traffic in the San Diego area at the time of the incident. The document includes a reference to 1st Lt. James D. Bunch, who served as the Senior Director for the report.
