Project 10073 Record: Sighting in Chicago, Illinois, 17-18 June 1966

This document contains records related to a UAP sighting in Chicago, Illinois, on 17 and 18 June 1966. The witness, identified as a policeman, reported observing objects in the sky near 26th Street and Kostner Avenue. In the initial report, the witness described approximately 12 white lights arranged in a horizontal line, which blinked on and off consecutively. The objects were reported to be traveling west at an altitude of 500 to 800 feet, before changing direction to the south, then east, and finally north. The observation lasted approximately 10 minutes. A subsequent report, dated 21 June 1966, provided a different description, noting three cylindrical objects ringed with square lights at an altitude of 2,000 feet. The witness stated the objects moved ahead and then stopped moving in a circle. The Air Force, through Major Hector Quintanilla, Jr. of Project Blue Book, informed the witness on 10 August 1966 that the information provided was insufficient for evaluation and requested the completion of FTD Form 164. The official conclusion for the initial report was 'Aircraft (possible)', while the final evaluation for the 18 June report was 'Insufficient data for evaluation'.
