Project 10073 Record Card — Parksburg, Pennsylvania, 2 March 1955

This document contains a series of reports and record cards regarding a sighting on 2 March 1955 in Parksburg, Pennsylvania. A civilian Ground Observer Corps (GOC) observer reported seeing numerous red objects that appeared to expand to 6 to 8 feet, explode, and burn to a yellowish-green color. The observer noted that these events occurred repeatedly every few minutes over the course of an hour. The sighting was initially treated as a potential Unidentified Flying Object (UFO) incident. Subsequent investigation by the 26th Air Division, specifically Flight 3-H, involved a telephone check with the Aberdeen Proving Ground. This inquiry confirmed that the Proving Ground was conducting 75 mm anti-aircraft (AA) artillery tests at the time of the reported sighting. The investigation concluded that the observer had witnessed these aerial bursts. The document also includes a separate, unrelated narrative titled 'A Mirage of Sirius,' which describes a scientist's experience observing a flying saucer-like object while flying over Alaska, which he later identified as a mirage of the star Sirius caused by atmospheric distortion. The primary record card for the Parksburg incident explicitly categorizes the event as 'Other: AA Firings' and notes that the sighting was positively identified as test fire.
