Project 10073 Record Card — San Diego, California, 24 May 1958

This document is a Project 10073 record card and associated teletype report concerning an unidentified aerial phenomenon sighting on May 24, 1958, in San Diego, California. The witness, a 44-year-old civilian employee of Convair Astronautics, reported observing a red, oval-shaped object, described as the size of a pea, exhibiting radical movements. The object was observed for approximately 10 minutes, moving from the West toward the North. The witness reported the sighting to the 751st ACWRON. The investigation, conducted by 2/LT William E. Haggett of the USAF, concluded that the object was a balloon. This conclusion was based on balloon release schedules from Montgomery Field, which coincided with the time of the sighting, and meteorological data indicating that surface winds would have carried such a balloon into the observer's vicinity. Despite the investigator's formal conclusion that the object was a balloon with a light, the report notes that the observer was considered very reliable and that the investigator initially expressed uncertainty regarding the object's nature. The report includes technical details such as the observer's location at Karwey Mesa, the clear night sky conditions, and the specific flight path of the object. The documentation serves as a standard record of a military investigation into a civilian-reported UAP sighting during the late 1950s.
