Project 10073 Record — Sacramento, California, 31 May 1949

This document contains a Project 10073 record regarding a sighting reported by a civilian market fisherman in Sacramento, California, on 31 May 1949. The witness, who lived in a boathouse two miles north of the T Street bridge, observed 16 objects at approximately 11:50 AM. He described the objects as discs, similar in color to the clouds, flying in a square formation at an estimated altitude of 2,500 feet. The witness noted that the objects appeared to be moving at 'aeroplane speed' and that they disappeared and reappeared three times before turning northeast and vanishing. The witness explicitly mentioned that while there were white cranes in the area, he had never seen them fly in such a formation or at such speeds. The document includes a formal acknowledgment letter from Lt. Colonel A. J. Helistreet, Jr. of the USAF Intelligence Department, confirming that the sighting was made a matter of record for the study of unidentified aerial phenomena. The official conclusion recorded on the form categorizes the event as 'Other (BIRDS)'. The witness also included extraneous commentary in his letter regarding his observations of brush fires and his belief that some were acts of sabotage, mentioning a conversation with an individual he suspected of being an FBI agent.
