l. 'The attached color slide, taken by a Canadian tourist while visiting
the United States, was forwarded to ATIC by your of fic The picture
was taken at Leadville, Colorado on 4 June 1960, and is reported to
show an unidentified flying g object which the witness also reported
seeing.
2. Utilizing measurements from the slide, and info ration provided by
the witness concerning the witness concerning his photograp his photographic equipment pmenc, the I ollowing facts •llowing facts
were determineds
a. The estimate of the elevation (45) of the object as reported
by the witness is far out of line. T by the witness is far out of line. The average elevation is much The average elevation is much
closer to 20. closer to 20o.
b. The b. The witness reported that the shutter speed setting for the witness reported that the shutter speed setting for the
picture was l/5o0. This means that the object traveled through the picture was 1/500. This means th ob ject traveled through the
entire field, approximately 45 in that time. This works out to an that time. This works out to an
angular velocity of 22,5o0 degrees per second. At a distance of angular velocity of 22,500 degrees per second. At a distance of
10 miles this represents a linear velocity of approximately 2000
nautical miles per second,. l20,Oo0 nautical miles per minute or mawtioolr od 100
7,200,000 knots. If the object is assumed to be l00 nautical miles .
from the witness, add another zero to the linear velocities. If the
witness could see this object, he must have no trouble at all watching
bullets which "slow" along at such relatively low speeds as approxi-
mately lloo feet per second. If such an object were to be seen at
all, it would appear as a flash.
c. Utilizing the speeds for l0 nautical miles distance and the
average of the l-3 seconds that the witness reported the object in
view, this object would then have traveled approximately 4000 nautical
miles.
d. The slide gives indication that the camera was not pointed at
the object as would be expected under the circumstances, but was level
with the horizon.

e. The object is in the middle of the photograph and yet the
supposed trail left by the object is in two directions from points on
the object located diametrically. This discounts the possibility of
the object making the trail.
f. There is no evidence of an attempt by the photographer to
follow the object (panning).
g. The witness reported that there was no sound from the object.
If the object had been moving as fast as already indicated in this
correspondence, sound would probably have been in evidence due to the
probable intensity and apparent closeness of the object. Meteors which
travel at the relatively slow velocities of 45 miles per second are
heard on occasion.
From the evidence available, the ATIC conclusion is that the twin
disc-like object on the slide is probably a lenticular cloud. The
picture was probably taken through a window and the streak which was
mistaken for a trail i is due to streaks on this glass.
4. Further analysis of this sighting by ATIC would be enhanced by Further a analysis of this sighting by ATIC would be enhanced by
determining the following from the witness: determining the following from the witness:
b. Was the picture taken through a closed - i window? window?
