Report of Information on Unconventional Aircraft - 13 Dec 1950

This document collection comprises official military correspondence and intelligence reports regarding an Unidentified Aerial Phenomena (UAP) sighting that occurred on December 13, 1950, near Winooski, Vermont. The primary report, originating from the 4700th Air Base Group at Stewart Air Force Base, details a message received from the First Army regarding a cigar-shaped object observed over Lake Champlain. Four witnesses, including a mill hand, a store clerk, a student, and a housewife, reported seeing the object at approximately 2100 hours. According to the accounts, the object was orange-red in color, estimated to be four to five yards in length, and traveled from Canada southward before executing a sharp 'L' pattern turn toward White Face Mountain. The witnesses noted that the object moved faster than any conventional aircraft and emitted a large, fiery trail, though no sound was heard. The weather conditions at the time were described as having a light haze with visible stars and moon. The information was initially relayed to L/Sgt J.W. Flynn of the Vermont National Guard at Fort Ethan Allen. Subsequent intelligence assessments by the 1st District Office of Special Investigations (OSI) noted that the reliability of the witnesses remained unknown and that no photographs or physical evidence were available. The report was submitted in compliance with AFCSI Letter No. 85, dated October 23, 1950. The documentation also includes a separate, unrelated reference to a sighting in Utah, which was dismissed by the District Commander due to conflicting weather reports from the Hill Air Force Base weather station, illustrating the standard procedure for evaluating such intelligence reports during this period. The documents are marked as Confidential and include instructions for downgrading at three-year intervals.
