3307TH TRAINING SQUADRON (CONTRACT FLYING)
MARANA AIR BASE
Marana, Arizona

15 April 1952

SUBJECT: Sighting of Unidentified Aerial Object
TO: Whom it May Concern

On 3 April 1952, I landed T-6D number 406 at the Benson,
Arizona, airport at approximately 0745 for the execution of
"sround control" for student cross-country flights. I was in
the company of » Who is also a civilian instructor
at Marana Air Base.

Shortly after taxiing into position for the best observation

of aircraft which would be turning, over Benson airport and shutting

off my engine, we were joined by Mr. " SEERamaFIEES anager of
the airport. The position of my aircraft was in the NW corner
of the airport approximately 100 yards east of the hangar and
facing a direction of 255 degrees M,.

At approximately 0805, Mr. ; was assigned
the position of patrol, landed his T-6D aircraft and taxied in
close proximity to my aircraft and parked facing in the opposite
direction.

With my radio on and remaining seated in the front seat
of my aircraft I was awaiting radio transmission from the
students when Uv wR 6 22° my attention to a bright
object which appe e size of a bright star and
was prominent enough so that ones' attention was drawn to it
even though attention might be distracted mementarily. In other
words, there was no necessity to scan to relocate the object.
At the time my attention was called to this object I thought
nothing of it but when, approximately six or seven minutes later,
Mr ointed out the fact that it was still there, it
impressed me as being rather odd that any airborne object could
maintain the same position for this length of time. It occured
to me to take a fix on this object in relation to the top of
the canopy and take note of the time, which I did. The time
was 0823 (I time checked with the tower before take-off from

Marana) and the object was approximately two and one-half inches
above the canopy when I was centered in the seat.

During this time Mr -qgemnepenetic ir attention
had been drawn to the object. At approximately 0830 Mr. Logan

took off to see if he could get a better look; I kept in touch

with him by radio and I believe he climbed to 13,500 ft.
(elevation of Benson airport is 3500 ft.). He reported he could

see it slightly be estimated its altitude at from 30,000

zo 40,000 ft. Mr hen descended and landed again at
enson. .

During this time, and until it disappeared, I kept taking
sights on this object and it never moved the slightest fraction
in relation to the canopy of my aircraft, which during this
time, had not moved.

At 0914 Mr RR, 0 had been an intent observer of
this object, wa rom a position on the right side of the
fusilage and took up a position at the right wing tip. This
change of position took approximately fifteen seconds. When
he reached this new position he remarked that the object had
disappeared. I checked, using my sighting reference and found
the object had vanished. Two or three of the students had also
noticed the object while passing over Benson.

During the time of timed observation, from 0823 to O91,
this object did not change size, position, nor intensity and
vanished completely in approximately 15 seconds.

APPENDIX III “
a - 3 A-ril 1952

I, DESCRIPEION OF rNOTUENT

ba 3 April 1952 at 0815 MST, three civilian AF pilot instructors and several
other people observed an object fron the Benson, Arizona, airport. The object
war about the size of a bright ster but was prominent enourh to be continually
observed (1.e, not necessary to scan the sky to find 1t),

At 0823 MST, one of the instructors took a fix on the object by sitting in
a T=6 and siphting across the canony with the aircraft on a neasnetic heading of
255° at the tinc. Fixes were taken at intervels until 0914 et t which time the
objcet diseppeared, The object dii not nove during the 51 agian hes period, How
the object disan-eared is not known as cne of the obsorver'’s attention was dis-
tracted for about 15 seconds and wien he locked up the ob; ect t was gone.

One of the instructors flew a T-6 up to 13,500 ft. in an ettempt to better
observe the object, however, there wes no relative change in the size,

Several cadets flying T-6's in the area also observed the object,

II, STATUS OF TEc INVESTIGATION

The excellent forethought of the instructor to take continual fixes on the
object has eliminated the possibility of the object being an aircraft or balloon

since no motion was observed. In addition, an investigation was made and it was
deternined that there were no balloons in the area.

It is possible that the object was a bright planet. This is doubtful,
however, since a planet would appeer to move some in 51 minutes.

The approximate elevation of the fix: has been requested, In the original
report it was given as "two inches above the canopy". This angle will depend
on height of the pilot, height of seat, etc, When this information 1s received,
a nearly exect fix can be obtained and know astronomical becies checked,

15 April 1952

SUBJECT: Sighting of Unidentified Aerial Object

TO: Whom it May Concern

On 3 April 1952, Squadron TI, Class 52-G, was assigned a trianguler
cross=country navigational flight, viz., Marana - Winkleman - Penson -
Sell - Marana, Arizona. Each of tha above Arizona cities represented a
turn, ---At-each-turning-point there was assigned ea tean of instructors
for the purpose of acting as radio communication center, checking cach
cadat ag he flew over. One aircraft was held in readiness to petrol the
erea in the event ono of the cadets. missed the turning point. This air-
ercft was termed the Patrol. Ship.

My duties this date consisted of flying the Patrol Ship at the
Benaon, Arizona turning point. I landed at Benson Airport approximately
at 0515. Soon after I landed, one of cur cadets flew over at an sltitude
of approximately 10,000 ft and called in over the radio, giving his ship
number, nome, and that he was enroute to tha next turning point. For
positive identification he was requested to turn left or right (T do not
remember exactly) and we spotted this alreraft by vision. This pro-
cedure necessitated our vision to be constantly directed upward.

My MUP one of our instructors, spotted an object in the
sky and directed our attention to it. It was a bright, silvery object,
hanging motionless in the sky at an altitude I would guess to be some-

where above 50,000 ft. It was not exactly round, but rather oval in
appearance,

I watched it for about thirty or forty minutes, and felt it peculisr
that it did not move, but rather hovered in that same spot where it had
been first observed.

A cadet by the na? aI fe over and 1 RRBs octet
him to the object, asking if he could see what it was. 2 endat came
back with, "Sir! It looks like a flying saucer".

At this time I decided to observe the object as closely as possible
so I took off and climbed to an altitude of 13,500 ft. I did not have
oxygen. At this altitude the object did not look lerger. It waa more
brilliant because the sky was clearer and bluor. I flew around for

about five minutes with the canopy open, then descended and landed,
The object was still there in the sky.

After a little tine, Mr. asked if I could see the object.

I looked upward, and could not, oni y 4) >
airport manager, looked and it was obvious that the object had disappeared,

It is the opinion of this individuel that the above described
Object, could have been a great deal higher than I have expressed in
this report. My judgment as to height is naturally based upon sone

know size of objects I am familiar with, I know what an airoraft looks
like at certain heights.

This object could have been any height from the earth's surface,

@l). depending on its size. Therefore, my guess as to altitude and sive
could be incorrect,
