appeared over Alaska. The witness, a scientist who held the rank
of Commander in the United States Navy, was returning from the
North Pole on the daily Air Force Ptarmigan weather flight; his
mission had been to study the effect of the aurora on radio prop-
agation, for the Department of Defense. He described his ex-
perience as follows:
A Mirage of Sirius
"We were flying southwest of Point Barrow, Alaska, not far from
the Bering Strait, en route to Eielson Air Force Base in Fairbanks,
and our course was roughly southeast. The night was clear and the
stars shone brilliantly. I was looking out of the western bomb blister
when suddenly I saw a bright object shoot in at tremendous speed
from the horizon, directly toward the plane. At first I thought it was
a meteor or a fireball and I instinctively ducked, but the object came
to a sudden skidding stop about 3oo feet away, thereafter riding
along with our plane and keeping pace with our speed. I could
scarcely believe my eyes. The thing possessed greerr and red signal
lights that flashed back and forth, and something that looked like a
lighted propeller on the top. Beyond question, it was a flying saucer.
"I wondered if the thing might be a hallucination, brought on by
fatigue. After all, we had been in the air almost seventeen hours.
itself occasionally wove or dipped. My next thought was to eliminate
all possible chance that the thing was an internal reflection. I pulled
my fur parka up over my head and put my face smack against the
bulging surface of the blister that formed the window. Thus
shielded from all internal illumination, I could still see the glowing
object. I next drew a pencil from my pocket and held it out at arm's
length, and was surprised to find that the glowing disk was some-
what smaller than the eraser. I made a rapid calculation and con-
cluded that if the sphere was actually 3oo feet away, as it seemed,
then it was only a foot or two in diameter, not much larger than a
basketball. My next thought was whether one of the radio para-
chutes had somehow or other got attached to the plane by the
string. These objects, brilliantly lit by an electric light, can be quite
startling. But it had been ncarly half an hour since the last para-
chute release and the meteorologists were just getting ready to
lower another through the trap. I decided to call the meteorologist
to look at the thing. But before I could call out, as if it had read my
mind, the object suddenly took off at top speed and disappeared.

might be a secret Russian missile on reconnaissance. I kept my eyes
glued to the point where the saucer had disappeared and suddenly,
a couple of minutes later, it shot back toward the plane, more bril-
liant and spectacular than the first time.
"You can perhaps imagine my relief when I suddenly realized
what the object was, and at the same time realized that I had hit
on the answer to a great many flying-saucer reports of a similar
nature. Only someone familiar with the constellations could have
identified the object. It was a mirage of Sirius, the brightest star in
the heavens. Actually Sirius was slightly below the horizon at this
time, but the bending g of the light had raised the image above the
horizon and had diffused the beam into the saucerlike form. The
flashing red and green lights were common phenomena associated
with star twinkling, and the apparent structure, i including the
whirling propeller, resulted from distortion by the carth's atmos-
phere.
"But why had the image taken off the way it did, and then rushed
back? The moving plane of course was continually changing position
relative to the ground features. A mountain peak on the distant
horizon had briefly come between the plane and the star, obscuring horizon had briefly come between the plane and the star, obscuring
the light. The light was not cut off all at once, however. Thus as
the image dimmed it seemed to shrink, as though it were racing the image dimmed it seemed to shrink, as though it were racing
away. This temporary barrier also explained the sudden stops and away. This temporary barrier also explained the sudden stops and
starts and the tremendous instantaneous acceleration the object theobject
seemed to make at the instant it appeared. The large atmospheric seemed to make at tha instont it nberio
lens was simply focusing the light of the star in the general direction
of the plane and thus it was centered with my eye. That is why the
object seemed to duplicate the motion of the plane.
I watched the object for several minutes after its return. I was
able to get full confirmnation of this identification when the star rose
over the western horizon; it rose in the west because the southward
motion of the plane more than compensated for the westward ro-
tation of the star. And as Sirius came up from the horizon, the "flying
saucer" sank back into the brilliant hemisphere of stars, where it
belonged." (The witness in this case was the senior author of this
book.)
