Project 10073 Record Card and Related Correspondence — Hazel Green, Wisconsin, April 1960

This document details a UFO sighting reported on April 11, 1960, near Hazel Green, Wisconsin. The report, filed by 1st Lt. Robert P. McKay, Jr. of the Air Technical Intelligence Center (ATIC), describes an incident involving three 'brilliant elongated discs' observed by a family on a farm. The witnesses reported that the objects, which were described as having the size of a large transport aircraft, were initially seen in an abreast formation before changing to a triangle and then a trail. The objects were observed for four to five minutes, moving from the northeast to the northwest while hovering and moving slowly. The witnesses claimed to have captured the event on 8mm color film. The report notes that the sighting was initially brought to the attention of the Air Force by a reporter from the Dubuque Telegraph Herald. Despite the claims of photographic evidence, the film was never received by ATIC, leading investigators to conclude that the claim was invalid. Major F. H. Willcox, in his analysis, suggested that the objects were likely light-colored kites flown by children, noting that such kites are common at that time of year and can be moved in 'patterns' that might be misinterpreted by observers. The final evaluation of the report by the Air Force was that it was 'prob soft' and likely the result of exaggeration, possibly influenced by prior publicity regarding UFO sightings in the area. The document includes technical weather data for the time of the sighting, indicating clear conditions with high instability between 3,000 and 6,000 feet, but no other unusual meteorological or astronomical activity was identified.
