Project 10073 Record — Dixon, Illinois, December 1963

This document contains a Project 10073 record regarding a civilian sighting of four unidentified flying objects in Dixon, Illinois, in December 1963. The witness, a heavy equipment engineer at the Medusa Cement Plant, reported observing four flying saucers at 1245 PM. According to the witness, the objects were initially fuchsia in color, approximately 40 feet in diameter, and were observed at altitudes between 400 and 1500 feet. The witness described the objects as moving in a line, with one object performing a dive from 1500 feet to 400 feet before climbing at a 90-degree angle. The witness reported the objects made a sound like wind closing in behind a large bullet or electric motors, and noted that they changed color to chrome before turning invisible. The witness also claimed the objects appeared to be gravity-free. The official conclusion recorded on the Project 10073 form is 'Psychological.' The file also includes correspondence from August 1965, in which the witness wrote to President Lyndon B. Johnson regarding the sighting. The Air Force responded to the witness, explaining that the investigation of unidentified aerial phenomena is the responsibility of the Air Force under Project Blue Book. The response stated that in 18 years of investigations, no evidence had been found that UFOs represented extraterrestrial vehicles or posed a threat to the United States, and that all reported phenomena were attributed to man-made objects, atmospheric conditions, or celestial bodies.
