Project 10073 Record: Sighting Report - Greenfield, Wisconsin, 26 March 1966

This document contains the official Air Force record and subsequent correspondence regarding a UFO sighting reported in Greenfield, Wisconsin, on March 26, 1966. The witness, a housewife, observed a single, round, orange-red object with a dome and a glow for approximately five to seven minutes between midnight and 12:07 A.M. The object was initially stationary before descending with a swaying motion. The report was processed under Project Blue Book and Project 10073. The investigating officer, 1st Lt. Frank L. Howe of HQ Chicago ADS (SAGE), noted that the object's altitude was approximately that of air traffic or balloons. However, the official conclusion reached by Major Hector Quintanilla, Jr., Chief of Project Blue Book, was 'Insufficient Data.' This was due to the witness failing to return the required FTD Form 164 within 30 days of the request. The file includes a formal letter from Major Quintanilla to the witness, dated April 5, 1966, requesting the completion of the form to facilitate further evaluation. A handwritten annotation on the primary record suggests an inquiry into the position of the moon at the time of the sighting, questioning if it was rising or setting, which may have been a potential explanation for the observation.
