TL;DR

This document compiles UAP sighting reports from August 1956, including a detailed investigation of a Tacoma, Washington sighting that was attributed to a star distorted by a temperature inversion. It serves as a record of the Air Technical Intelligence Center's efforts to categorize and evaluate various aerial reports during that month.

This document is a collection of records and press clippings regarding Unidentified Aerial Phenomena (UAP) sightings reported in August 1956. The primary document is a Project 10073 Record Card detailing a sighting on August 18, 1956, in Tacoma, Washington. The witness reported a round, blue and white object, the size of a dime at arm's length, which appeared to form a triangle with two other stars. The object was observed for over an hour, moving from the east, stopping in the sky, and eventually moving west. The 4602d AISS conducted a limited investigation and concluded that the phenomenon was likely the star Deneb, observed through a temperature inversion. The file also contains a compilation of press clippings from various locations across the United States, including Cincinnati, Ohio; Willsboro, New York; Santa Monica, California; Middlebury, Connecticut; Pittsburgh, Pennsylvania; Parkersburg, West Virginia; Cortland and Ithaca, New York; and North Windham, Maine. These reports describe various sightings of lights, round objects, and 'flying saucers' throughout mid-August 1956. Additionally, the document includes a report from Kuopio, Finland, regarding a strange light phenomenon sighted on August 18, 1956, which was described as a ball of light that disappeared into a cloud. A summary table of sightings from August 19-31, 1956, is provided, categorizing various reports as 'Astro (MARS)', 'Aircraft', 'Balloon', or 'Insufficient Data'. The document also contains military communications (teletype) regarding the Tacoma sighting, confirming the details provided on the record card, and a news clipping about a Navy 'Sky Hook' balloon flight, which may have been relevant to the context of high-altitude sightings during this period.
