Project 10073 Record Card — Sighting near Susanville, California, 19 September 1960

This document is a Project 10073 record card detailing an unidentified aerial phenomenon sighting that occurred on September 19, 1960, north of Susanville, California. The report describes a single, cucumber-shaped object with an impression of transparency. The witness, identified as a civilian, observed the object for a duration of 30 to 40 minutes. According to the report, the object emitted a bright light and appeared to follow the witness's truck, at one point crossing directly in front of the vehicle. The movement was described as having a 'floating action' rather than abrupt maneuvers. The object reportedly flashed four times before disappearing in a steep climb toward the east-northeast. The weather conditions at the time were noted as clear with no clouds and good visibility. The official conclusion reached by the Air Technical Intelligence Center (ATIC) was that the sighting was likely caused by a temperature inversion in the area, citing the random movement and the nature of the light as supporting evidence for this atmospheric explanation. The report notes that the witness was considered reliable, having been interviewed by the Sheriff's Office.
