Project 10073 Record — Marengo, Indiana, 4 February 1969

This document contains a Project 10073 record regarding a UFO sighting reported in Marengo, Indiana, on February 4, 1969. The primary witness, a 16-year-old male, reported observing a single, round, black object for approximately eight minutes. The witness, who was accompanied by his sister, Rena Bell, described the object as having a large, bright light and three smaller lights around its edges. He estimated the object to be 50 feet in diameter, traveling at 500 mph at an altitude of 600 feet. The witness noted that the object emitted a humming sound and appeared to veer away from an airplane that was in the vicinity. The witness stated that the object eventually moved toward the east and disappeared behind some trees. The Air Force, specifically the Aerial Phenomena Office of the Foreign Technology Division, reviewed the report. Lt. Colonel Hector Quintanilla, Jr. determined that the information provided was initially insufficient for a scientific investigation, leading to the request for the witness to complete an AF Form 117. The final conclusion recorded in the Project 10073 file is that the object was a 'Possible AIRCRAFT,' noting that its flight characteristics and duration were similar to those of an aircraft.
