🇺🇸 USAF — Project Blue Book
A round object the size of a baseball was observed in Detroit, Michigan, in August 1956. The witness, a 29-year-old woman, saw it while walking in her yard. The object had a yellow-white color and remained visible for an unknown duration. Although no photos or radar were used, the presence of weather balloons in the area was noted. This led to the consideration that the object might have been a balloon, although it was not confirmed with certainty.
The sighting was recorded as a ground visual and no further details such as trajectory or speed were reported. The Air Force reviewed the case and classified it as "possibly balloon," without reaching a definitive conclusion. This type of report reflects the uncertainty surrounding many sightings in the 1950s, when technology and communication were not as advanced as today.
