Project 10073 Record Card and UFOB Index Card — Baltimore, Maryland, June 1955

This document consists of a Project 10073 record card and an AISS-UFOB-180-55 index card detailing a UFO sighting that occurred in Baltimore, Maryland, on June 17, 1955. The report describes a single oval-shaped object observed by a civilian witness at 0210Z. The witness, identified as a chauffeur residing at 911 Cord Street, reported that the object appeared to be the size of a silver dollar held at arm's length. The object exhibited a color change from red to white and blue, remained stationary at times, flickered, and changed in brightness before moving in a straight line and disappearing abruptly. The observation lasted for approximately five minutes under clear, dry, and windless weather conditions. The witness used a small telescope during the observation. Military communications included in the file show the report was routed through the 347th AC&W Squadron to the Air Technical Intelligence Center (ATIC) and other Air Defense Command units. The official conclusion recorded on the index card states that the length of the observation and the characteristics of the object point to a balloon sighting, despite the initial record card noting 'insufficient data for evaluation.'
