Project 10073 Record Card — Detroit, Michigan, 27 August 1956

This document is a Project 10073 record card and associated teletype report detailing a UFO sighting that occurred on 27 August 1956 in Detroit, Michigan. A 29-year-old female witness, identified as a sales lady, reported observing a single, round, yellow-white object while walking in her yard. The object was described as being the size of a baseball. The report indicates that the observation was made via ground visual, and no radar contact or photographic evidence was obtained. The military investigation, conducted under the guidelines of AFR 200-2, concluded that the object was likely a weather balloon. This conclusion was supported by information provided by a Captain in the USAF, who noted that weather balloons were active in the area and had been launched from either Selfridge Air Force Base or Willow Run. The documentation includes technical details regarding the weather conditions at the time, noting scattered clouds at various altitudes. The report was processed by the 661st ACWRON at Selfridge Air Force Base and forwarded to the Air Technical Intelligence Center at Wright-Patterson Air Force Base for evaluation.
