Project 10073 Record Card — Parkview, California, 31 December 1957

This document is a Project 10073 record card detailing a sighting of an unidentified aerial object on December 31, 1957, in Parkview, California. The witness, identified as a social worker, reported observing a single, cone-shaped object that appeared to be in three sections, featuring a square body and a round object below. The object was described as being as bright as a new nickel and roughly the size of an automobile. The sighting lasted for ten minutes, during which the object moved from east to west. The witness noted that the square and round parts of the object stayed together but appeared to be separated. The weather conditions were reported as clear with no clouds, and jet trails were visible in the sky. The report indicates that the witness looked away and, upon looking back, could no longer locate the object. The official conclusion reached by the evaluating agency, ATIC, was that the object was 'Probably Balloon,' citing the description, duration, and flight path as the primary factors for this assessment. The report was processed through military intelligence channels, including the Air Defense Command and the 27th Air Division.
