This document comprises UFO sighting report cards from Project 10073 (the U.S. Air Force's UFO investigation program), dated June 5, 1955. The first card documents a civilian ground visual observation near Santa Margarita, California, of a single round white object described as stationary. The report notes insufficient data for evaluation, with comments suggesting it might possibly have been a balloon. The second card provides similar information from the same location, describing a round white object "the size of a head of a pin held at arm's length" remaining stationary over Santa Margarita. The conclusion suggests "Possibly Balloon," noting that two nearly simultaneous reports from locations fourteen miles apart may represent the same sighting, and that many balloons were released in Southern California at the time.
