U.F.O. Sighting Report — Chicago, Illinois, 1 December 1965

This document is a formal sighting report filed with the 928th Troop Carrier Group, Medium (Reserve) of the United States Air Force at O'Hare International Airport, Chicago, Illinois. The report details an observation made on 1 December 1965 at 0155 Zulu by a 22-year-old civilian witness. The witness observed a single, bright orange, oblong object at the intersection of Madison Avenue and Ridgeland Avenue in Oak Park, Illinois. The object was described as being approximately the size of a paperback book when held at arm's length. The witness noted that the object featured a series of windows or panels that tapered toward the end of the object. The object followed a straight flight path and was visible for 5 to 10 seconds before it was obscured by a building. The witness reported that the object's light went out and then came back on. No sound was associated with the object, and no physical evidence or photographs were obtained. The weather was reported as clear. The investigating official, Ernest M. Hegeler, a Civilian Aircraft Dispatcher, noted that the witness appeared confident in his account. Hegeler further remarked that he had personally observed aerial night advertising in the area in recent weeks and suggested that the reported object could potentially be the same type of phenomenon.
