1947.
This is to advise that two arIJ\1 officers reparted to the
Office of the Director of Intelligence, headquarters Alaskan Departnent,
at 1''ort Richardson, Alaska, that they had witnessed an object passing
through the air at a tremendous rate of speed which could not be judged
as to miles per hour .
The first officer stated that his attention was attracted to
this airborne object, and he in turn pointed it out to the second of
ficer. The object appeared to be shaped like a sphere and did not give
the inpressi on of being saucer-like or co~arable to a disk. The first,
officer stated that i t would be impossible to g:i,ve minute details con
cerning the object, but that it appeared to be approximatel y two or three
feet in diameter and did not l eave any vapor trail in the sky. ,--

Both officers atteapted to determine the approximate altitude
of the object, and from a weather group stationed nearby it was de
termined that cloud .formations at the time the object was sighted were~
"scattered above 10,000 .feet. 11 The object was noted to be traveling
belc:M' the cloud formation .
The first officer stated that in his opini on the object ap
peared to be metallic and was silver in color, nuch like the color of
many airpl anes .
• The second officer stated substantial ly tbe same facts and
also pointed out that the object renained within his vision for ap
proxi.nately 15 to 20 seconds. When sighted, the object was traveling
due south at a speed considerabl y in excess of any plane . The second
officer stated that the object appeared to him to be approximately 10 μfeet in diameter and compared it to half the size of a full moon on an
ordinary night . The seco~ officer based the altitude at approximately
the same as the first officer except for the fact that due to the size
be believed the object to be, he estimated the altitude to be only
approximately 3,000 or 4,000 feet . The object appeared broadside to
the second officer, and no evidence of a spinning motion or reflection
was noted. As to the color, the secoxt~ pointed out that it
appeared to be a dull retal finish.9 ~ -. . (J
