Unidentified Flying Object Sighting Near Manhattan Beach, California

On July 27, 1952, at 1835 PST, an unidentified aerial object was observed over Manhattan Beach, California. The primary witness, an ex-Navy pilot currently employed as an aircraft engineer, observed the object both visually and with the aid of 20/50 binoculars. The witness was accompanied by seven other individuals at the same address. The object was described as elliptical or delta-shaped, appearing to the naked eye as the size of a dime. It was bright silver in color with a grey rear section. Initially appearing as a single object, it broke up smoothly into seven distinct objects, which then formed a stack of coins-like formation, specifically a V-formation of three objects followed by two formations of two objects each. The entire maneuver was described as very graceful. The object was observed overhead at Manhattan Beach, where it turned south, broke up, and eventually disappeared from sight on a north-northeast heading. The object was noted to be traveling at a very high rate of speed at a very high altitude, with no exhaust trails or sound detected. Weather conditions at the time were reported as 18,000 feet with scattered clouds and 15-mile visibility. Winds aloft were recorded between 15 and 24 knots. Official investigations, including inquiries into local air traffic and weather balloon releases from the Burbank Weather Bureau and Long Beach AFB, concluded that no known aircraft or balloons were in the vicinity at the time of the sighting. The length of time observed and the speed of the object were cited as factors that eliminated the possibility of the object being astronomical in nature. The final official conclusion for the incident was recorded as 'UNSOLVED'.
