Project 10073 Record Card — St. Louis, Missouri, 17 November 1955

This document consists of a Project 10073 record card and an associated teletype report regarding an unidentified aerial phenomenon sighting that occurred on November 17, 1955, in St. Louis, Missouri. Two witnesses, a 64-year-old semi-retired man and a 60-year-old housewife, reported observing twelve objects in the sky. The objects were described as round and flat, with a dark underside and a silver top. They were flying in a formation of three abreast and four deep. The witnesses observed the objects for approximately 45 seconds, noting that they made no sound and appeared to tip from a horizontal to a vertical position while moving from left to right. The initial observation was made at a 75-degree elevation in the northeast, with the objects eventually disappearing over the horizon in the same direction. The weather was reported as clear with the sun shining. Military intelligence units, including the Air Technical Intelligence Center (ATIC) and the Air Defense Command (ADC), were notified of the event. The official record card lists the conclusion as 'UNIDENTIFIED (Birds??)', while the teletype report suggests a 'possible cause of sighting new type of aircraft in formation.' The report explicitly notes that there was no vibration or signs of power units observed, and that there was no radar contact.
