Project 10073 Record Card and UFO Report — 20 November 1958

This document is a Project 10073 record card and associated teletype report concerning an Unidentified Aerial Phenomenon (UAP) sighting that occurred on November 20, 1958. The incident took place at 1415Z over the Pacific Ocean, west of California, at coordinates 3447 N, 133.37 W. The sighting was reported by an individual seated in the right seat of a C-118 aircraft (MATS 33248). The witness described the object as a round, silver entity traveling at a high rate of speed and high altitude. The object was observed for approximately 15 seconds, moving in a straight line before fading out. The weather conditions at the time were reported as clear. The official conclusion reached by the Air Technical Intelligence Center (ATIC) was that the object was a meteor, based on the short duration of the observation. A secondary note in the report suggests that an operations officer from flight service mentioned the possibility that the object could have been a previously released weather balloon, though the final conclusion recorded on the project card explicitly identifies it as a meteor.
