MEMORANDUM FOR RECORD
PROBLEM:
Tremont~-f'
Utah, sighting.
FACTS AND DISCUSSION:
On 15 Dec 52 Lt A.G. Flues telephoned Lt Malcom Ross, USN, at the Of
fice of Naval Research, University of Afinnesota. The purpose was to deter
mine whether pillow balloon releases could account for the Tremon~..,_,Utah,
incident of 2 Jul 52.
Lt Ross had seen the Tremon-tP1n'ovies and it was his opinion, as well as
that of Lt Lewis, ONR, that the objects photogr~phed were pill-0w balloons.
However, Lt Ross said that the Navy had not .f:el~ased any pillow balloons in
or near that area at that time. Lt Ross po~nted out that General Mills, Inc.,
Minneapolis, is, in so far as he knows, the ·sole manufacturer of pillow bal
loons and suggested that ATIC contact-1,±'~ J. R. Smith of General Mills to
determine what organizations and ageheies had purchased pillow balloons. Lt
Ross also stated that in the winter of 1952, the 11 Crusade for Freedom" pur
chased many pillow balloons from General Mills. These were sent to various
cities in the United States and released periodically. Lt Ross did not know
the exact times, dates, or points of these releases, but he suggested that
ATIC contact the 11 Crusade for Freedom".
REOOMdENDATI0N:
That ATIAA-5 contact Mr. J. R. &iith and the 11 Crusade for Freedom"~
