Project 10073 Record Card — Wheaton, Illinois, 20 May 1956

On May 20, 1956, a civilian witness in Wheaton, Illinois, reported observing an unidentified aerial object for approximately 25 minutes. The object was described as round, bright, and white to pink in color, appearing to be the size of a dime held at arm's length. The witness noted that the object was drifting toward the northwest. The incident was reported to the 755th Aircraft Control and Warning Squadron (ACWRON), which subsequently initiated a formal inquiry. The military communication, transmitted via teletype on May 21, 1956, provided detailed parameters of the sighting, including the observation conditions, which were noted as clear with 15 miles of visibility. The report was processed under the designation UFOB 1676. Following an investigation by the 755th ACWRON, the military concluded that the sighting was, in all probability, caused by the planet Venus. This conclusion was recorded on the Project 10073 record card, which serves as the primary summary document for the event. The documentation includes the original teletype message sent to various Air Defense Command and intelligence units, confirming the details of the observation and the subsequent identification of the object as a celestial body.
