Project 10073 Record Card — Incirlik AFB, Turkey, 31 December 1958

This document is a collection of records and reports concerning Unidentified Aerial Phenomena (UAP) sightings occurring in December 1958. The primary record is a Project 10073 Record Card detailing a sighting on December 31, 1958, in the vicinity of Incirlik Air Base, Turkey. The witness reported a long, slender object of a dull color with a rear glow, which they compared to a jet tailpipe. The object was observed at an altitude of approximately 5,000 feet, flying parallel to a runway before turning and climbing rapidly out of sight. The official conclusion for this incident was that the maneuvers and description were characteristic of an aircraft. The document also includes supplementary materials, such as a photograph of a UFO taken by Dr. Stanislaus Kowalczewski in Poland on December 22, 1958, and brief reports of other sightings. One report describes a giant sphere with green and red lights that allegedly chased a truck near the Mexican border in Southern California, causing the truck's paint to blister and its instruments to malfunction. Another report details a glowing, oblong light observed by ranchers near Floyada, Texas, on December 10, 1958, which moved in circles at a low altitude for 30 minutes. Additionally, the document contains a page from the 'Science News Letter' dated November 29, 1958, which discusses astronomical phenomena, including the planet Mars and the Geminid meteor shower, providing context for the sky conditions during this period.
