Project 10073 Record Card — Chicago, Illinois, 31 August 1960

This document is a Project 10073 record card and associated correspondence regarding a UFO sighting in Chicago, Illinois, on August 31, 1960. The report was forwarded by Captain Richard N. Woda of the 3245th Operations Group to the Air Technical Intelligence Center at Wright-Patterson Air Force Base. The witness, an insurance agent with a college degree, reported observing a light in the northeastern sky from a third-floor apartment overlooking Lake Michigan starting at 11:35 PM. The witness initially observed one light, which was described as stationary and hovering, with a brightness comparable to a distant automobile headlight. At approximately 12:45 AM, four additional objects appeared, and all five seemed to form an arc. The witness reported an unceasing whirling sound associated with the objects, noting that this sound was also heard during the daylight hours of the previous and following days, though no visible sources for the sound were identified. The objects were described as solid with colors of green, yellow, and red, and were viewed through eyeglasses and binoculars. The sky was reported as clear with no wind. The official comments on the record card suggest that the objects were likely the star Capella, which was rising in the NNE horizon at that time, and that the witnesses were looking over the lake toward that direction.
