Project 10073 Record: UFO Observation, 2 August 1966, Oak Lawn, Illinois

This document contains a Project Blue Book record regarding a UFO sighting reported by a civilian in Oak Lawn, Illinois, on August 2, 1966. The witness, an amateur astronomer, observed a single object at approximately 10:15 p.m. The object was described as white, changing to red, and appearing round. The witness reported that the object made abrupt movements, wobbled, and pulsated red light twice before moving at a high speed. The witness estimated the object's speed at 600 mph and its altitude at 30,000 feet. The observation lasted approximately 10 seconds. The witness explicitly stated that the object was not an aircraft. Following the report, the Foreign Technology Division of the U.S. Air Force, under the direction of Major Hector Quintanilla Jr., sent a letter to the witness on March 24, 1967, requesting that they complete a formal FTD Form 164 questionnaire, as the initial information provided was insufficient for a scientific evaluation. The witness subsequently completed the questionnaire, providing detailed sketches and descriptions of the event, including the object's path relative to Polaris and Midway International Airport. The official conclusion recorded on the Project 10073 record remains 'INSUFFICIENT DATA FOR EVALUATION'.
