PROJECT 10073 RECORD CARD — Glendale, California, 17 November 1957

This document consists of a Project 10073 record card and associated military teletype communications regarding an aerial sighting in Glendale, California, on November 17, 1957. At 1427Z, a witness, identified as a police officer and deemed reliable, observed a single reddish-yellow ball of fire in the sky. The object was reported to be emitting smoke and a flash while appearing to fall from east to west. The weather conditions at the time were reported as clear. The military investigation, conducted by the 27th Air Division and reported to the Air Technical Intelligence Center (ATIC), concluded that the sighting was likely a meteor or bolide. Captain Smith, a Senior Controller, explicitly noted the possibility of a meteor, and the official record card reflects this assessment, stating that the description provided by the witness is typical of a fireball or bolide. The report includes technical data regarding the atmospheric conditions, noting a strong inversion layer between 14,000 and 16,500 feet, though this did not alter the final assessment of the object as a natural astronomical phenomenon.
