This is the printed record of a July 29, 1968 symposium on unidentified flying objects held by the Committee on Science and Astronautics of the U.S. House of Representatives, chaired by Rep. J. Edward Roush. The committee heard statements from six scientists: J. Allen Hynek, James E. McDonald, Carl Sagan, Robert L. Hall, James A. Harder and Robert M. L. Baker. It also printed papers from Donald Menzel, Stanton Friedman, Frank Salisbury and others. Hynek argued that puzzling UFO reports from competent witnesses deserve serious scientific study.

He estimated its speed to be in the neighborhood of 100 to 200 mph, yet no engine
noises of any kind were audible. It appeared dark against the bright cloud
background, but bright when it was seen against blue sky. No obvious explana-
tion in conventional terms seems to fit this sighting.
7. Many other sightings by both professional and amateur astronomers could
be listed. Vallee (Ref. 17) discusses in detail a November 8, 1957 observation
by J. L. Chapuis of Toulouse Observatory in France of what appeared through
a small telescope to be a yellowish, elliptical body, with distinct outlines, leaving
a short trail behind it. It was seen by other observers in three separate locations,
executed maneuvers entirely excluding meteoric origin, and was regarded as an
unexplainable phenomenon by all of the witnesses. Hall (Ref. 10) lists nine
examples of astronomer sightings of unidentified objects, several of which are
quite striking. Ruppelt (Ref. 5) remarks that an astronomer working under con-
tract to the official UFO investigatory program interviewed 45 American astrono-
mers during the summer of 1952, of whom five (11 per cent) had seen what they
regarded to be UFOs. Although the sample is small, that percentage is well
above the population percentage who say they have seen UFOs, which suggests
that perhaps astronomers may sight more UFOs than they report as such. In-
deed, with the recent publication of Ref. 7, further interesting information on
that 1952 poll is now at hand. The contract astronomer wrote at that time (Ref. 7,
Rept. 8), ". . . certainly another contributing factor to their desire not to talk
about these things is their overwhelming fear of publicity. One headline in the
nation's papers to the effect that 'Astronomer Sees Flying Saucer' would be
enough to brand the astronomer as questionable among his colleagues." Unfortu-
nately, we scientists are by no means as open-minded and fearlessly independent
as we are sometimes pictured. It is often quite difficult to persuade a scientist
to let his confidential report of a UFO sighting become a fully open UFO report;
and my own experience suggests that perhaps 'astronomers, as a group, are just
a bit more sensitive on this score than other scientists. At any event, perhaps
the above-cited cases will suggest that some astronomers have seen unidentified
flying objects.
METEOROLOGISTS AND WEATHER OBSERVERS LOOK AT THE SKIES FREQUENTLY.
WHY DON'T THEY SEE UFOS ?
1. Case 26. Richmond, Va., April 1947
To begin an answer to that rhetorical question, we might consider an observa-
tion made by a weather observer at the Richmond, Va., U.S. Weather Bureau
station, about two months before the first national publicity concerning UFOs.
Walter A. Minczewski, whom I located at the same Weather Bureau office where
he made the sighting in 1947, was making a pilot balloon observation, when
he spotted a silvery object that entered the field of his theodolite (which was
trained on the balloon he had released). In the account that Minczewski sent
me, he stated that "the bottom was flat and the top was slightly dome-shaped":
and when he tried to see it with naked eye, he could not spot it. (Typical pilot
balloon theodolites have magnifications of about 20 to 25, and angular fields
that are usually about a degree across.) It was a "clear bright morning" when
he spotted the object, and it lay to his NNE at an elevation of about
45 degrees. Whether Minczewski really saw the upper surface or formed his
mental impressions without realizing that the theodolite may have inverted the
image is now unclear, and my questioning did not settle that point.
Discussion.—A report of this sighting is in the official files, a circumstance
Which greatly surprised Minczewski, since he had discussed it only with his fel-
low workers. In the ensuing two decades, he has never again seen anything like
it. Clearly, the probability of an object crossing the small angular field of a
meteorological theodolite is quite low, if only chance were involved here. He
tried to track it but lost it, due to its high angular velocity, after about five or
six seconds, he recalled. No obvious conventional explanation suggests itself
for this early sighting.
2. Case 27. Yuma, Ariz., February 4, 1953
Weather Bureau observer S. H. Brown was tracking a pilot balloon at 6000
ft over Yuma at 1:50 p.m. MST on 2/4/53 when first one and then a second
unidentified object moved across his theodolite field, somewhat as in the pre-
ceding case. I obtained an account of this sighting from V. B. Cotten, Meteorolo-
gist-in-Charge at the Yuma station. The full account is too long for recapitula-
tion here. Both objects appeared to be of the order of a minute of arc in diameter
