This Department of War release reproduces Project Blue Book records on the Tremonton, Utah film of 2 July 1952. In them, Navy Chief Photographer Delbert C. Newhouse explains how he filmed a group of bright objects near Tremonton. ATIC memos and a December 1952 travel report record Navy and General Mills balloon specialists judging that the objects closely resembled pillow balloons. A January 1953 memorandum discusses publicly releasing the film. The file also includes unrelated sighting reports from Phoenix and Massachusetts, plus material about Donald Keyhoe.

Photogrammetric• -2- Serial ~ ~sis ot "utah" Film This "utah" tilm clip together with a ''Montana" UFO tilm clip (~is ot Photographic Material, Serial 01) came into the possession of Green-Rouse Productions at Samuel Goldwyn Studios, 1041 North Fo:nDOsa Street, Hollywood, vho incorporated both tilm clips as s:f8n1t1cant evidence in a Documentary Film, "Unidenti.tied FqiDg <J,jects'1 tor release by United Artists to public theaters by May 9, 1956. A 35mm reprint ot the Newhouse "Utah" film was submitted by the Studio to Douglas Aircraft C~ tor e.xamin.Btion. Visual study ot the reprints on the Recordak and astronomical plate measuring engine revealed the toll.ow ing: the tilm comprises about 1,200 frames; on most ot the frames there appear JDBDY' round white dots, some elliptical. The dots often seem clustered in cODStellations, or formations which are recasnizable tor as long as seven teen seconds. A relatiTe motion plot (obtained tran an overlay vellmn trace on the Recor4ak) ot two typical formations are presented 1n figures 2a and 2b. The objects seem to cluster 1n groups ot two's and three's, see actual blowups, 4a, 5b, and 6c. On same t'remes they flare up and then disappear tran view in 0.25 secon4s or less and sometmes they appear as a rand~ scattered "tv1nkling" of dots. The dot images themaelTes show no stnicture; they are White and have no oolor ~inges. Exam1n.-tion under a microscope shO\ls the camera to be well focused as the e<!ges ot the inlagee are sharp and clear on many ot the properly exposed ~emes. .Angular diameters range from about 0.0016 to O.ooo4 radians. Their pattern of motion is essentially a curvi linear milling about as shown in tigure 2a and 2b. Sam.etimes the objects ap pear to circle about each other. There are no other objects 1n the field at v1ev- which might give a clue as to the absolute motion of the cluster. In the overlay trace, tigure 2, the trane ot reference is determined by a certain object whose relative motion during a sequence of frames remains rather constant (indicated 1n the figures). T'h.1e object is used as a refer- enae PQint and the lower edge ot the trame as abscissa. Assuming the camera to have been kept reasonabl;y uncanted., the abscissa vould be horizontal and the ordinate vertical. In the overlay trace, figves 3a and 3b, the particular frame 1tsell 1e used as the ref'erence. Assuming the camera vae held ste~ (there is an unconsciCIIJS tendency to pan with a lDGVing object) the coordinate system is (llasi-ti.xed. It is realized that both of these coordinate systems are in actuality moving, possibly possessing both velocity and accelerati011. No alt1t\14e or azimllth determination can be made because ot lack ot background. The only measurable quantities of interest &re theref'ore the relative angular distances between the objects and their time derivatives. Graphs ot two typical time variations ot relative angular separation and velocity are 1nclJ1ded as figures 7 and 8. The relative angular velocity is seen to vary t'rom zero to O.oo65 radians per second. The relative angular acceleration had a maximum value at 0.0036 radians per second squared. Bupposing the camera vas kept stationary the average angular velocities tor the object moving across the tield. are 0.039 and 0.031 radians per second tor tigu.res 3• and. 3b. The angular velocities in these sequences scmetimes vary erratic~ t'rcm 0.07 to 0.01 radians per second. This variation may be attributed in part to camera "JiggliDg" and in part to the object's DECLASSIFIED Authority NND 923007
