Project 10073 Record Card — La Grange, Illinois, 15 September 1963

This document contains a Project 10073 record card and associated correspondence regarding a UFO sighting reported by a 17-year-old civilian in La Grange, Illinois. On September 15, 1963, at 18:15 DST, the witness observed a single, extremely bright, yellow-orange object for approximately 35 minutes. The witness described the object as having a 'flat cigar' shape, which exhibited erratic movement, including hovering, climbing, and changing speed and direction. The witness noted that the object made no sound and appeared to move behind a radio tower. The witness, who identified themselves as having studied UFOs for three years, submitted a detailed U.S. Air Force technical information questionnaire in March 1964. The Air Force responded on May 27, 1964, via Major Maston M. Jacks, informing the witness that the object had been evaluated as a balloon. The correspondence also includes the witness's requests for information on UFOs for a science project and the Air Force's standard reply providing a fact sheet on Unidentified Flying Objects.
