Project 10073 Record Card — Harvey, Illinois, 14 August 1956

This document consists of a Project 10073 record card and an accompanying military teletype report regarding an Unidentified Aerial Phenomenon sighting in Harvey, Illinois, on 14 August 1956. The report details an observation made by two witnesses, both described as reliable, who observed a single circular object for approximately two hours. The witnesses described the object as being ten times larger than a star, with colors shifting between white, blue, and amber. The object was reported to be high in the sky, moving east, and exhibiting unusual behaviors, including swinging like a pendulum, rotating on an axis, and emitting sparks or rays. One witness compared the appearance of the object to a half-dollar coin held at a 45-degree angle. The observation was conducted both with the naked eye and through field glasses. The military report, filed by the 755th ACWRON, notes that the object remained in the area for a duration inconsistent with a balloon, given the prevailing wind speeds of 25-40 knots. The report also mentions that a similar object had been sighted in the same location one week prior by five individuals. Despite the detailed descriptions provided by the witnesses, the official conclusion recorded on the project card suggests the phenomenon was a 'probable sighting of Mars' in the eastern sky. The document includes standard military routing information and references compliance with Air Force Regulation 200-2.
