Project 10073 Record Cards and Related Correspondence — November 1957

This document is a collection of Project 10073 record cards and teletype reports detailing a series of sightings that occurred on November 30, 1957, across Southern California. Numerous witnesses, including military personnel and civilians, reported observing a bright, round object, often described as having a blue and white flame or trail, moving in an arc from south to north. The sightings were reported from various locations, including San Clemente Island, Blythe, Oxnard, Ventura, and San Bernardino. The 27th Air Division and the Air Technical Intelligence Center (ATIC) investigated these reports, with multiple officers and observers concluding that the phenomena were consistent with a large meteor or meteorite. The reports include specific details such as the duration of the sightings (typically around 5 seconds), the appearance of the objects, and the weather conditions at the time. In addition to the California sightings, the document includes information regarding a separate incident in Leme, Brazil, where a strange object fell from the sky on November 29, 1957. This object, described as a black wheel or cluster of filaments, was analyzed by the Instituto de Pesquisas Tecnologicas in Sao Paulo. The analysis concluded that the filaments were composed of fiberglass coated with organic matter, likely resulting from incomplete combustion. The document also contains a press clipping regarding a woman in Ohio who reported seeing a rocket, which she believed to be Sputnik I, and mentions the Moonwatch team's efforts to track such objects. The overall tone of the military reports is one of systematic evaluation, with a consistent conclusion that the primary California sightings were astronomical in nature.
