Department of War · 2026-09-18 · 156 pages · text from the file's own layer

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.

500 ft. of altitude which could account for a high or low balloon, with relation
to the group, to proceed in an apparently- opposite direction.
If the objects are pillows, the consensus was that they- are not over
6,000 1 altitude, probably- much less. If this is so, they cannot possibly- have
been aloft for more than 12 hours, and this only if filled with warm air or
underinflated with gas or ballasted for a given altitude. There is a much
greater probability that they are ascending and have been released from a
nearly point not over 1/2 hour before.
None of the persons present placed much faith in the computations of
angular velocity, since all were predicated upon Newhouse's holding the camera
still.
Lt Flues went over to GMI later on and obtained. from J. R. Smith the names
and addresses of consignees who received. pillow balloons during the period Sep
51 - 2 Jul 52. Also Lt Flues picked up some photos of pillow balloons and the
flight tracks of three Navy Skyhook.a released in Sept 52 from Tillamook, Ore. Gen
eral Mills had no movies of pillows which approximated the Tremonton films aa
GMI 1s footage seemed to be, shot against cloud background and when the balloons
were lower. However, they will be launching pillows from Wendover, Utah, in
Feb 5.3 and will make movies then.
The course of action recommended was for ATIC to check all persons in the
western u.s. who received pillows. There were some other shipments to Gl1I home
and farm appliance stores, and J. R. Smith agreed to send ATIO the names and
addresses of such consignees.
