"Sighting of flying objects"

The location Yuma County Airport, February 4, 1953, time 1350 M.S.T.

I was using a theodolite to follow a pilot balloon, which was at 6,000 feet

Mean Sea Level, I took my eyes away from the eye piece for a few seconds,

returned my eye to the eye piece, and the balloon was out of the field.

The readings were 53 degrees elevation, and direction from me 157 degrees,

time 1550 M.S.T. I then saw one object going upward, and surving to the

West. I had a clear sky background, and although it moved through the

field rapidly was able to see it clearly, and follow the flight. About

20 seconds after sighting the first object a second object came into the

field, and swooped upward and across the path of the first object. The

first object flew toward the West, while the second object swooped across

or near the path of the first object three to four times, going out of the

field about two times for a moment. The two objects passed near the lower

portion of the sun, and were traveling westward, the second object below

and behind the first object, when a Cirrus cloud came into the theodolite

field, I lost sight of the two objects. The exact position at that time,

elevation angle 29.1 degrees and direction from the instrument 204.1 degrees,

The time 1355 M.S.T., after having followed the two objects through the

32 power theodolite for a period of 5 minutes with a clear sky background.

The objects were both the same size, as nearly as I can figure one minute of are in also. The objects were almost round, a solid, dull, pure white color, with a thin white mist completely edging each object.

I am a Meteorological Aid employed with the United States Weather Bureau, having followed balloons through a theodolite for the past ten years. I also hold a private pilots license, and having flown in military and still aircraft frequently in the past ten years.

I am absolutely certain of what I have seen through the theodolite described in the foregoing paragraphs.

SUMMARY: (Enter concise summary of report. Give significance in final one-sentence paragraph. List inclosures at lower left. Begin text of report on AF Form 112—Part II.)
On 4 February 1953, Mr. Stanley H. Brown, 403 22nd Avenue, Yuma, Arizona, a meteorological aid for U. S. Weather Bureau was searching for a lost weather balloon with the aid of a theodite. At 1350 MST he sighted a solid white, oblong object at a direction of $ 157.2^{\circ} $ and elevation of $ 53.3^{\circ} $.
The object was a solid white color, oblong in shape and appeared to be covered by a small thin, white mist. The size of the object was 1 minute of arc.
It appeared as ascending straight up then leveled out in a long swoop at an elevation of $ 53.3^{\circ} $. Some 20 seconds later this object was joined by a second object, exactly the same as the first in size, color and shape. Object No 2 appeared from the left below and crossed No 1 to a position above. It then crossed No 1 again to a position below. This was done several times. In doing so, No 2 left the field of theodolite twice but re-entered and remained behind and slightly below object No 1. The changes in direction of object No 2 were smooth swooping turns. As the objects moved rapidly across the horizon, they remained the same relative size.
They both disappeared simultaneously at an angle of $ 204.1^{\circ} $ at an elevation of $ 29.1^{\circ} $. At $ 204.1^{\circ} $ the sky was covered by cirrus clouds at approximately 25000 ft. The clouds obscured the objects and they were immediately lost from sight. At the time of original sighting there was a clear sky background. The objects were lost momentarily when they passed near the sun. They reappeared on the edge of the sun.
The objects remained in vision for approximately 5 minutes. Coordinates of the theodolite are lat. $ 32^{\circ} 40 $ minutes N and long. $ 114^{\circ} 36 $ minutes N.
Mr. Brown was looking for his lost weather balloon with the aid of the theodolite at a 6000 foot level when the objects were first sighted. He did not find his balloon. He was standing at an elevation of 199 feet on the south side of the Yuma County Airport terminal building. Mr. Brown states that the objects moved much more rapidly than any balloon he has ever sighted in his 10 years experience as meteorological aid. The objects moved against the winds aloft which were from the west. Surface wind was from the north at 5 N.
Mr. Brown feels strongly that he actually saw a solid object other than any known aircraft. There was no glimmer or reflection from the sun. There are no other witnesses.
Mr. Brown called the 4750th Air Base Group at Yuma County Airport and then reported it to Security Control at Los Angeles Air Traffic Control.
Mr. Brown was aware that there were aircraft in the area but they were not in the immediate area of vision.
