UFO Observation Inquiry and Response — Bessemer, Michigan, December 1966

This document consists of a correspondence exchange between an unidentified civilian in Bessemer, Michigan, and the United States Air Force's Project Blue Book office at Wright-Patterson Air Force Base. In a letter dated December 1, 1966, the civilian witness reported observing an unidentified object in the north-northeastern sky on clear nights during October and November 1966. The witness described the object as being positioned 45 degrees above the horizon and moving slowly to the south. The witness requested information or pamphlets on unidentified flying objects to share with their eighth-grade science class. On December 19, 1966, Colonel Louis DeGOES, Director of Technology and Subsystems, responded to the inquiry. He informed the witness that the provided information was insufficient for evaluation and requested that the witness complete an attached FTD Form 164. To assist the witness, the Air Force enclosed a brochure on Project Blue Book, which included articles by Dr. Carl Sagan and Dr. Charles Smiley, as well as an extract from Wernher von Braun's book, 'First Men to the Moon.' The official conclusion recorded on the FTD form for this case is 'INSUFFICIENT DATA FOR EVALUATION.'
