UFO Sighting Report — Yosemite Park, California, August 15, 1964

On August 15, 1964, two individuals were camping on the southeast side of Benson Lake in the Yosemite wilderness area of Northern California. At approximately 8:15 a.m., while sitting by the lake, they heard a brief sound of rushing air. Upon looking up, they observed three bright silver objects moving from east to west at an incredible speed. The witnesses noted that the objects were moving on a parallel course but at variable forward speeds, with the objects adjusting their positions relative to one another. The objects disappeared behind a cloud in the west within 3-4 seconds. The witnesses, one of whom had prior service in the U.S. Army Air Force, estimated the altitude to be between 5,000 and 7,000 feet. They described the sound as being caused by air friction, explicitly noting the absence of jet propulsion noise. The objects were described as small, appearing similar to spheres or balloons. Following their report to the U.S. government, Major Maston M. Jacks of the USAF Public Information Division responded on September 30, 1964, stating that the initial description lacked sufficient detail for a full evaluation and requested the completion of form FTD 164. The case file was subsequently forwarded to Dr. J. Allen Hynek in December 1964.
