PROJECT 10073 RECORD - Waterloo, Iowa Sighting

This document is a Project 10073 record detailing a UFO sighting that occurred in Waterloo, Iowa, on September 17, 1967. The primary witness, a 42-year-old lawyer, observed a yellow, golf-ball-sized object moving in level flight at a constant speed at an altitude of 300 feet. The observation lasted for two separate intervals of 10 and 5 minutes. The witness used 7x35 binoculars to aid in the observation. The report notes that three other sightings were reported to the Waterloo Airport between 0115Z and 0200Z, all of which were described as similar. An investigation was conducted by contacting the UFO officer at the Waverly Air Force Station. The officer confirmed that the control tower had not seen anything and expressed that he was almost positive the object was a balloon. The official conclusion recorded on the document is 'Probable (BALLOON)'. The report includes weather data and notes that no physical evidence was found and no unusual aerial phenomena were detected by local radar, which reported only normal traffic.
