Project 10073 Record — Holt, Michigan, 21-22 July 1964

This document is a Project 10073 record concerning a UFO sighting in Holt, Michigan, on the night of July 21-22, 1964. A civilian witness reported observing a single, bright, white object for four to five minutes. The object was described as having a beveled, sharply outlined appearance, moving erratically, and hovering. The witness noted a loud, shrill sound, which was later identified in official correspondence as being of higher intensity than a standard aircraft engine. The report includes a formal letter from Major Hector Quintanilla, Jr., of the Aerial Phenomena Branch at Wright-Patterson AFB, addressed to the Michigan State Police. Major Quintanilla explains that the sighting was likely an aircraft conducting low-level photographic missions, similar to those reported in the Lansing area during May 1964. These aircraft reportedly fly at altitudes of approximately 500 feet with landing lights illuminated. The correspondence acknowledges the assistance of TSgt David Moody and Bill Powers from Northwestern University in investigating these events. The document also contains a blank U.S. Air Force Technical Information questionnaire and handwritten notes identifying Michigan State Police officers, including Cpl. James Arndt and Sgt. Gordon Grenwis, who were involved in the local investigation. The official conclusion suggests the phenomenon was an aircraft, noting that many such missions carry a security classification due to the specialized equipment or operational nature of the flights.
