TO WHOM IT MAY CONCERN:

On the afternoon of 25 May 1949, I was in the Supply and Salvage

Yard with Colonel Petersen and Mr,. Shaughnessy of the Air Inspector's
ffice, and:Lt Gable and Mr. Van Leeuwen of Base Salvage, While we

were standing in the yard discussing the condition of the Salvage Yard, |
I heard an airplane overhead, which sounded to me to be quite high. I.”
Looked into. the sky in the direction from which’ the sound seemed to be
coming and.could not discern.the plane. However, in scanning the sky,
I observed a-globular object traveling slightly east of south, at what
I estimated to be apvroximately the same speed that a C-L7 travels... ak
renarked to. the company in general that I sawa globular object and Lt,
Gable, after asking me the general direction, stated that he saw it
also, He also remarked that he saw one a while ago traveling in the
game general direction, I only saw the one and did not know that he
had seen one previously until I called his attention to the one 1 saw,
We discussed the probability of its being a weather balloons.

With no ‘basie for my judgment other than the fact. that when 1 first
saw it, 1 expected to see a plane, I estimated it to be at least 11,000
feet above sea level. The first view lasted possibly 15 seconds, after
which I lost. sight of it, then some 15 to 30 seconds later 1 saw it the
sacond time for possibly 10 seconds, With north as zero, I estimate —-
the first sight was at  otclock, Mr. Shaughnessy stated that he glanced
at his watch when I mentioned it and the time was 1407. "

The object seemed to me to be over the west slope of the Wasatch: .
Range and slightly south of due east of Hill Field, which if my impress-
ion of the -heighth and distance was correct would indicate that the. “<
obj eqt ‘wae..consid derabiy larger than a weather balloon,.

TO WHOM IT MAY CONCERN:

This is in relation to foreign objects I sighted in the air in
the vicinity of Hill Air Force Base at approximately 14,05 M on 25 May

199. rs

I was at the West Salvage Yard of Hill Air Force Base, escourting
Lt Colonel Petersen and party on an inspection visit and Mr, ggg
of the Air Inspectors Office and 1 stopped for a moment to discuss some-

thing or other, While talking with Mr. GQ I was watching an F-51
cruising south of the field, approximately eight miles, when ‘ sighted

a dull silver circular object which at first looked as if it were follow
ing the F-51, I thought it might be an aerial gunnery sleeve of some kind,
but the object was going approximately 0 “PH faster than the F=-51 and
seemed to be much father away and higher, Then the F-51 started to turn to
the left and the object went straight ahead until it was out of sight.

I turned to Mr. GOW and asked him to look, and pointed to the
direction I had seen it and asked him if he could see anything. He said
"No, I can't see anything there, but look over there." To the north of
the path of the first object and also going southeast, was another
circular object. The side away from the sun looked dark blue and the
other side was silver colored and flashed, as if reflecting sunlizht,
It boked like it was lower thanthe first object, traveling southeast
from the field and could be seen more clearly than the first ovject,

It was about the size of a full moon. Mr. g@iand I watched it for
maybe a minute until it disappeared from view and we wondered if it
might be a weather balloon at that time of day with a perfectly clear
sky except for a few scattered clouds far to the south,

We walked over to Colonel Petersen and told him what we had seen

and he advised us to call the OSI and let them know s0 they could check
on whether they were weather balloons or what: they might have been,
