Project 10073 Record Card and Incident Report — Middlebury, Vermont, 12 September 1955

This document consists of a Project 10073 record card and a follow-up teletype report regarding an Unidentified Aerial Phenomenon (UAP) sighting on September 12, 1955, in Middlebury, Vermont. The primary witness, a housewife in Weybridge, Vermont, reported observing a single, shiny, white object described as being 'like a top' and 'half the size of a dime.' The object was observed for approximately five minutes, drifting slowly in a northeasterly direction at an estimated altitude of 4,000 feet. The sighting was reported to the State Police, and the information was subsequently relayed to military authorities. A second observation of the object was reported by workers at the State Hospital in Waterbury, Vermont, at 1435Z on the same day. Military authorities from the 37th Fighter Squadron were requested to investigate the area one hour later but were unable to locate any object. The official conclusion reached by the investigating officer was that the object was a weather balloon, specifically identified as MDH # 112, which was known to be in the area at the time and was also drifting in a northeasterly direction. The report notes that although jet aircraft from the 37th Fighter Squadron were conducting routine training flights in the vicinity at the time of the sighting and did not report seeing the object, the presence of the weather balloon remained the most plausible explanation for the event.
