Station 8 followed an object for six consecutive frames, during
which time the azimuth angle changed uniformly from 58019'30"
to 58°26'30". The elevation changed uniformly from 47°32'20"
to 47°25

during which time the aximuth angle changed uniformly from

27 April pictures and made a repor copy of which I am

that triangulation effected from pictures taken on
24 May because pictures were taken from two stations. The

2. Captain elated from which still vivid, his experience
of an encounter with an UF0 on 29 May 1950. He was flying (in the left
seat of the cockpit ofa DC-6. The airplane had left Washington Airport
at about 9:10 p.m. and was steadily climbing towards 20,000 level.
The weather was clear aloft t but the ground covered by haze. There
was a full moon about 250 above the horizon. He was headed 240°(mag)
suddenly shouted: "Watch it, watch it!" and drew his attention
to an UFO ahead of them, growing rapidly bigger. It was a brilliant
bluish light. To avoid possible collision they sharply banked and
veered about 45 off their ourse to right while the object passed
by on their left side slightly higher in opposite direction from an
11 o'clock position to clock parent position. During this
maneuver UFO happened pass betweer observers and the upper

As the object had passed behind their wing pilots banked the plane
to the left and returned towards their old course. Even so, the copilot

Much later learned that "Hank Myers, later pilot President
Truman's plane, was flying an AAL airplane on the same evening and ob-
served a brilliant bluish object between Nashville and Knoxville at such
a time that it could well have been the same UFo".
3. The possibility that the UFO een by and his copilot was
a meteor was emphatically discounted by both. Capt. does not
believe that seemingly erratic apparent movement of the object t could
have been an illusion produced solely by the three veering maneuvers of
their own aircraft. The observation of the bright light being at what
they called the rear of the oblong or cigar shaped silhouette of the
object as it passed for fleeting fraction of a second i in front of the

A saucer incident that might have become a classic Unknown
occurred in Denver at 10 A.M. on a summer's day in 1950. A man
was sitting on the shady porch of his house, reading. Beyond the
porch roof the sun shone brightly. Glancing up from his book,
he was startled to see a formation of perhaps a dozen spherical
objects, shining iridescently, traveling toward the distant mountains.
As he watched, those in the front of the procession seemed to vanish
instantly while others appeared out of nowhere to join the parade
at the rear. Measuring their size against the mountain background,
he decided they were “immense” and they moved at fantastic speed,
covering the thirty or so miles to the mountains in a matter of five
or six seconds.

Too stunned to take action, he was still numb from shock when
he heard a faint “Hello,” and looked up—to realize that the little
girl across the street was blowing soap bubbles. If the man had
jumped up when he first saw the objects and had rushed into the

house to telephone the nearest saucer club, he might never have.
