This is Project Blue Book Special Report No. 14, "Analysis of Reports of Unidentified Aerial Objects," Project No. 10073, dated 5 May 1955. The study reduced about 4,000 sighting reports received by the U.S. Air Force between June 1947 and December 1952 to IBM punched cards and analyzed them statistically, including chi square tests comparing knowns with unknowns. It concludes that the reports very probably do not represent technological developments beyond present scientific knowledge, and it notes that no case produced physical evidence.

Case XII (Serial 3601.00)
, At 0535 on the morning of August 25, 1952, a musician for a radio
station was driving to work from his home when he noticed an object
hovering about 10 feet above a field near the road along which he was
driving. As he came abreast of the object, he stopped his car and got out
to watch. Having an artificial leg, he could not leave the road, since the
surrounding terrain was rough. However, he was within about 100 yards
of it at the point he was standing on the road. The object was not absolutely
still, but seemed to rock slightly as it hovered. When he turned off the
motor of his car, he could hear a deep throbbing sound coming from the
object. As he got out of the car, the object began a vertical ascent with a
sound similar to "a large covey of quail starting to fly at one time". The
object ascended vertically through broken clouds until out of sight. His
view was not obscured by clouds. The observer states that the vegetation
was blown about by the object when it was near the ground.
Description of the object is as follows:
It was about 75 feet long, 45 feet wide, and 15 feet thick, shaped like
two oval meat platters placed together. It was a dull aluminum color, and
had a smooth surface. A medium-blue continuous light shone through the
one window in the front section. The head and shoulders of one man, sitting
motionless, facing the forward edge of the object, were visible. In the
midsection of the object were several windows extending from the top to the
rear edge of the object; the midsection of the ship had a blue light which
gradually changed to different shades. There was a large amount of activity
and movement in the midsection that could not be identified as either human
or mechanical, although it did not have a regular pattern of movement.
There were no windows, doors or portholes, vents, seams, etc., visible
to the observer in the rear section of the object or under the object (viewed
at time of ascent). Another identifiable feature was a series of propellers
6 to 12 inches in diameter spaced closely together along the outer edge of
the object. These propellers were mounted on a bracket so that they
revolved in a horizontal plane along the edge of the object. The propellers
were revolving at a high rate of speed.
Investigation of the area soon afterward showed some evidence of
vegetation being blown around. An examination of grass and soil samples
taken indicated nothing unusual. Reliability of the observer was considered
good. .
