Final Personnel Record for Newhouse, Delbert C., U.S. Navy, 1957
🏛️ Department of War
This file contains the final personnel record of U.S. Navy Chief Warrant Officer Delbert C. Newhouse, who left naval service as a Chief Warrant Officer 4, then the highest Warrant Officer grade. In July 1952, Newhouse recorded 16mm motion-picture film near Tremonton, Utah; the film later became the subject of a Project Blue Book investigation. Project Blue Book was the U.S. Air Force program active from 1952 to 1969 that investigated the nature and origin of unidentified flying objects (UFOs). In addition to documenting routine assignments and training, the file records Newhouse’s career progression as a Photographer’s Mate, a Navy enlisted specialty responsible for photography and related imaging work. Project Blue Book investigators characterized Newhouse as an expert photographer based on his naval experience.

Project Blue Book Photo File Relating to Tremonton Film, Utah, 1952
Department of War
During its investigation of a July 1952 film of an incident reported near Tremonton, Utah, Project Blue Book examined whether the objects recorded on film might have been “pillow balloons.” Project Blue Book was a U.S. Air Force program active from 1952 to 1969 that investigated the nature and origin of unidentified flying objects (UFOs). In December 1952, investigators contacted General Mills, Inc., the only known manufacturer of pillow balloons at the time, to determine whether a balloon release could account for the incident. The file includes example imagery of pillow balloons supplied by General Mills Research Laboratories. In late December 1952, Project Blue Book personnel, balloon specialists, and representatives from General Mills reviewed the Tremonton footage. The group’s consensus was that the objects closely resembled pillow balloons in flight and behaved consistently with that explanation. One General Mills representative was less convinced, noting that the objects appeared somewhat too bright and seemed to maneuver too rapidly. The reviewers also questioned previous angular-velocity calculations suggesting that the objects moved at a high rate of speed because those calculations depended on the unverified assumption that the camera operator had held the camera still during filming. Subsequent efforts to identify a pillow-balloon release in the Tremonton area were unsuccessful. The file also considered seabirds as a possible explanation, citing similar films showing seabirds as bright points of light under comparable conditions. Later Air Force assessments favored the seabird attribution.
Project Blue Book File on Tremonton Film, Utah, 1952
Department of War
This document records the Project Blue Book investigation and subsequent assessments of an incident near Tremonton, Utah, on July 2, 1952. Project Blue Book was a 1952-1969 U.S. Air Force program to investigate the nature and origin of unidentified flying objects (UFOs). The file describes the Air Force’s assessment of the principal witness, Delbert C. Newhouse, a U.S. Navy Warrant Officer specializing in photography, as honest and reliable, and as an expert with more than 1,000 hours of aerial-photography experience. Newhouse reported observing 12 to 14 reflective objects and recorded the event on color motion-picture film using a handheld Bell & Howell Auto Master camera. The file reflects an evolving Air Force assessment of the imagery over several years. Early documentation considered several possible explanations, including sunlight reflecting from birds or balloons, and a mirage effect, and did not identify the objects conclusively. Later assessments became more confident that the objects were seabirds reflecting sunlight, citing identifiable seabirds and similar films showing seabirds as bright points of light under comparable conditions. However, the film’s limited detail and lack of fixed reference points prevented reliable determination of the objects’ distance, size, altitude, or linear speed from the film alone. AARO Comment: The file contains conflicting references to the film format. Several documents describe a 35mm film, while contemporaneous submission documentation identifies the original as a 50-foot roll of processed 16mm Kodachrome color motion-picture film recorded with a handheld Bell & Howell Auto Master camera. Newhouse reported exposing approximately 30 feet of the roll during the incident and using the remaining film later that day to record unrelated mountain scenery in Idaho. Other records show that 35mm positive and negative duplicate blowups were produced from the original 16mm material. The file also indicates that the original film was duplicated for preservation, citing its deteriorating condition. The footage retained by the National Archives and Records Administration and presented in this collection as DOW-UAP-PR159 is a digitization of a 16mm print.
Transcript of a Presentation by Captain Edward J. Ruppelt, 1952
Department of War
This document is a transcript of a March 1952 presentation by Captain Edward J. Ruppelt outlining the U.S. Air Force’s reorganized investigation into unidentified flying objects (UFOs). The presentation previews prospective technical methodologies, such as diffraction-grating photography and radar-scope synchronization, that were subsequently incorporated into Project Blue Book, a U.S. Air Force program active from 1952 to 1969 that investigated the nature and origin of UFOs. Ruppelt explains that out of approximately 800 historical cases reviewed by the Air Force, approximately 20% remained unexplained after technical analysis. These unresolved reports were sourced from credible military personnel, commercial pilots, and other qualified technical observers. He highlights geographic report concentrations around sensitive national security and nuclear weapons installations (including Los Alamos, Albuquerque, and Oak Ridge National Laboratories) and notes recurring anomalous characteristics, including silent high-speed flight and radar detections indicating unconfirmed air speeds between 1,000 and 3,500 miles per hour. Emphasizing that the Air Force found no conclusive evidence regarding the nature or origin of the phenomena, Ruppelt underscores the national security need for a systematic physical data collection effort to better evaluate these sightings.
U.S. Air Force Flying Discs File, 1952
Department of War
This file is an archival collection of U.S. Air Force Director of Intelligence records relating to reported “flying disc” incidents during the period from September through December 1952. Drawn from multiple governmental and non-governmental sources, it compiles a wide range of material associated with reported sightings and official handling of those observations, rather than presenting a single analytical conclusion on the nature or origin of “flying discs.” The contents include correspondence, memoranda, reporting forms, case summaries, distribution and routing material, and other administrative or intelligence-related documentation tied to flying-disc reporting and review during that period. Pages 26-36 of the file refer to an incident reported near Tremonton, Utah, in July 1952, in which a U.S. Navy Warrant Officer recorded film of unidentified objects that the Air Force later assessed were likely seabirds. Overall, the file is a broad documentary collection reflecting how such reports were recorded, circulated, and evaluated in late 1952.
