This document contains a Project 10073 record regarding a civilian sighting of an unidentified aerial phenomenon in Chicago, Illinois, on May 26, 1966. The witness, a 52-year-old individual, reported observing a stationary, yoyo-shaped object with white lights on its top, bottom, and sides for approximately 8 to 10 minutes.

The observer noted that no other individuals on the road appeared to notice the object. The report includes a follow-up letter from Major Hector Quintanilla, Jr., Chief of Project Blue Book, dated July 28, 1966, informing the witness that the initial information was insufficient for evaluation and requesting the completion of an attached FTD Form 164. The document also includes a questionnaire filled out by the witness and a comment from C.W. Salmonson, a civilian aircraft dispatcher, who noted that the witness believed certain pictures published in the Chicago's American newspaper on May 29, 1966, were similar to the object she observed. The official conclusion recorded for the incident is 'Other (CONFLICTING DATA)'.
