Project Blue Book File on Tremonton Film, Utah, 1952

This U.S. Air Force Project Blue Book file compiles 1952 and 1953 messages, memos and reports on the movie film Navy Chief Photographer Delbert C. Newhouse shot on 2 July 1952 near Tremonton, Utah. It records interviews with Newhouse's family, requests about the film, and Navy and General Mills balloon experts judging that the objects closely resembled pillow balloons. It also covers internal debate about releasing the film to the press. Unrelated reports from Phoenix, Lexington and Highland Park sightings are included too.

From the source:Release of 2026-09-18 Incident: 7/2/52, Tremonton, Utah. 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.

sufficiently to permit determination of the angular velocity of objects
which cross the field of view? (Reference particularly the si ngle object
which crosses field; photographer states that camera was held motionless
while object crossed field of view.)
j. Determine patterns of flight from position plots for each
frame , then:
(1) Is there any recurring pattern in the relative
position of the objects?
(2) Do they maintain same relative positions in formation
during any maneuvers, particularly violent maneuvers?
( 3) Is relative position maintained coincidental with
movement about their axes?
(4) If undulating motion is present among a number of
objects which are maintaining a semblance of formation,
do those objects undulate in phase? Ditto for tumbling
motion?
(5) Is there any indication of abrupt changes in direction
of flight path through fairly large angles (e . g. 900 or
more during interval of 2 or 3 frames)?
(6) Do any objects appear to remain motionless at the same
time that others move about?
(7) Can all objects be accounted for at all times or do
some literally disappear while still well within field
of view?
6. Although CPO Newhouse did not request that the film be returned
to him, it is reco:imnended that the final footage (of the mountain scenery) be
returned to him immediately and that he be asked if he . is willing to accept
a duplicate of the initial footage in lieu of the original. If his reply
is affirmative, suggest the duplicate be forwarded whenever available,
7, Request advice of the analytical results as soon as available .
