Project 10073 Record Card — Albuquerque, N.M., 2 February 1958

This document is a Project 10073 record card and associated teletype report concerning an Unidentified Aerial Phenomena (UAP) sighting that occurred on February 2, 1958, in Albuquerque, New Mexico. The witness, T/Sgt Marshall Corson of the 687th AC&W Squadron, reported observing a white, circular object, described as being the size of a pea, for a duration of seven seconds. The object was seen traveling from the southeast to the northwest before disappearing behind terrain. The initial observation was made at a 45-degree elevation, with the object disappearing at a 20-degree elevation. The observer was looking north at the time. The report notes that the object appeared to be moving a significant distance and possessed a sharp outline. Despite the clear weather conditions, the official conclusion reached by the Air Technical Intelligence Center (ATIC) was that there was insufficient data for a definitive evaluation. Internal notes suggest that a weather balloon was released in Albuquerque around the time of the sighting. The investigator posited that if the witness had misidentified his cardinal directions—specifically, if he had been looking south instead of north—the object could have been the balloon heading southeast. However, the report acknowledges that if the witness's orientation was correct, the object would have had to travel into the wind, which was inconsistent with the balloon's expected path.
