Project 10073 Record Card and Observer's Questionnaire — Sonoma, California, 20 August 1952

This document contains a Project 10073 record card and a completed observer's questionnaire regarding a sighting that occurred on August 20, 1952, in Sonoma, California. The witness, a 52-year-old female serving as a civilian ground observer for the Air Defense System, reported observing five flat, silver-colored objects at approximately 0932 PDT. The objects were described as round, disk-like, and slightly concave. The witness reported that the objects made no sound and traveled in a straight line before performing tight circular maneuvers for a few seconds and disappearing into a bank of clouds. The witness noted that she and another observer, Mrs. [illegible], saw the phenomena clearly and explicitly rejected the possibility of optical illusions or reflections, stating that the objects appeared to have substance, solidity, and direction. The report includes a sketch of the objects' path and shape, as well as the witness's personal details and her assessment that she had no way of knowing what the objects were. The documentation was processed by the Air Technical Intelligence Center at Wright-Patterson Air Force Base.
