he saw this strange elliptical object go across the from about ten degrees
* to the northeast of the horizon to about forty degrees above the southwest
horizon where it was cut off by the roof of the Sears store. The duration
of the sighting was only three or four seconds, and the object moved about fifty
or sixty degrees during that time. The statement made in his original letter
that the object was moving from looo to 3000 seconds of arc per second at a time
is erroneous; he was basing that on any miscalculation of Baker-Nunn camera
tracking rates. had been one of the men I employed as a satellite

to the object which was not fuzzy. It seemed cocked
seemed to be a demarcation between top and bottom. When asked what he
would have put up in the sky to simulate the object, he said he would
put t up two pearly white picnic plates glued together. He said object
had no bumps on it at all. He has idea at all of what it might have
been. He said that if it was an aerodynamic in nature, it should have
been in a turn because of its cocked position, but it flew in a com-
pletely straight t line. He tried visualizing it as a sweptback plane
but could not. The hind end was just about the same shape as the front---
a pretty good oval. He looked for a trail, he looked for an
apparent change in shape. He could see aircraft at great distances and
identify them. He saw three twin-engine Fairchilds. He saw transports
coming in towards Hanscom and he heard a transport shortly afterwards
but no sound from this object. He did not obse through a window but
was leaning out of the car trying to point out transports t son
immediately.
I quizzed him about the l000 to 3000 seconis of are per second, and he admitted
that this was a gross miscalculation since this would give only about two degrees
for the total duration of the sighting, and this is entirely out of question.
He also quickly dismissed the idea that it might have been a gull
He said this occurred to him at the time he was making the sighting, but it did not
jibe with the facts.
So we have another unidentified that falls in the general pattern of rapidly flying
discs in straight trajectories. Despite the shortness of the observation, consider

weight must be given to the excellence of the observer who, in this case, was
trained for specific tracking of objects in the sky.
He will be in Washington during his State Department training, and if any furthe
questions arise, I can get touch with him there.

Sir:
On Wendsday May 26 I observed something
which I can only y class as an unidentified flying object.
Below given are the notes I made immediately after
the sighting:
Place: Car-park in front of s Sears Roebuck Store, Mass.
Ave., Cambridge.
Time: 19:43 hrs. [I checked my wrist-watch against
WCRB time signal at 20:1 hrs. after sighting.J
Met. Conditions: Estimated 5/10 cumulus. base est.
2,500', vertical development. Visibility
unlimited.
Appearance of object: Very thin ellipsoid as seen,
onnoximatelvs 5:1 Would
correction from DST.] First
Speed: Appeared equivalent Estimating
from a different datum I should guess it at between
1000 to 300 seconds r second.
Time visible: Disregarding short periods when object
appeared behind clouds I probably tracked i t for 35
to 40 of arc at which point i dissapeared behind the
roof edge of the Sears store.
