Project 10073 Record Card — Gimili RCAF Station, Canada, 5 November 1957

This document comprises a Project 10073 record card and associated teletype communications regarding an unidentified aerial phenomenon observed on 5 November 1957 at the Gimili RCAF Station in Canada. The sighting was reported by a civilian meteorologist who observed a single, round object, described as being the size of a pinhead. The object initially appeared white, then changed to red, and remained stationary before moving in a south-to-north direction. The observation lasted approximately five minutes. The report notes that the witness was monitoring for night-flying aircraft from the 916th Squadron at the time of the sighting. Official conclusions recorded on the card indicate that there was insufficient data to definitively identify the object, though it was suggested that it could have been a balloon. The comments section explicitly states that wind and launch data were missing, which prevented a more conclusive evaluation. The teletype correspondence confirms the transmission of this report from the 916th Squadron at Beausejour, Manitoba, to the Commander of the Air Technical Intelligence Center (ATIC) at Wright-Patterson Air Force Base and the Director of Intelligence at HED USAF. The document includes a hand-drawn sketch illustrating the relative positions of the observer at Gimili, the 916th Squadron location, and the direction of the object's movement relative to the wind. The Duty Director noted that there was no speculation as to the cause of the sighting beyond the possibility of a balloon, citing the lack of necessary meteorological or launch data to verify the object's nature.
