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.

Dr. SAGAN. That is just what I was going to say. Certain velocity
and altitude limitations.
Mr. BOONE. With that I agree. But I don't think we make many
sightings at that altitude. We do have a problem here of what you
want to look at. So in fact I think the thrust of Dr. Baker's argument
here was that most of the Air Force equipment do not supply the
material you would like to have.
So you are going to have to go to a much lower altitude, and you
are going to have to check a much larger number of targets.
Dr. SAGAN. I may have misunderstood, but my understanding was,
since all of these "uninteresting," trajectory objects are thrown away,
we have no way of knowing at the present time whether there are or
are not large numbers of interesting objects at altitudes above 90,000
feet.
Mr. BOONE. What this means is you check each one and determine
its trajectory, and then throw it away, so it no longer becomes a sim-
ple task of saying "Oh,I only want to look at the unidentified ones."
I have to check each one, and discard it.
Dr. SAGAN. Isn't that being done already?
Mr. BOONE. No,it doesn't do it below certain altitudes.
Dr. SAGAN. Right.
Mr. BOONE. All right. Certain targets are picked up at certain
ranges, are they not?
Dr. SAGAN. Right. So therefore the suggestion is that within the
altitude range,that is being used anyway by the surveillance radar
Mr. BOONE. You complicate the procedure.
Dr. SAGAN. Slightly.
Mr. BOONE. The procedure is used but it involves the software again
which is much more difficult to add to the systems than I believe is
being presented. It can be done, there is no question it can be done.
Dr. HARDER. I would agree the amount of effort that goes into the
relative softwares, although by no means a $100 million project, it is
not a very simple project.
Mr. RousH. Dr. McDonald,do you have a comment?
Dr. MCDONALD. Yes. I would underscore another one of the points,•
the general points that Dr. Baker made. I think it addresses itself to
the question raised. Both scientists and members of the public are quite
aware we have many monitoring radar systems, optical and so on.
This question is raised often, why aren't ITFO's tracked? The point
one is struck with in studying each of these systems in turn is the large
degree of selectivity that is necessarily built into them. Good examples
were cited by Dr.Baker.
It has to be kept well in mind that even systems like SAGE when
they were developed necessarily had to have programed into them
certain speed limits both lower and upper, certain safe requirements
like if the target was on an outbound path it could be ignored. In
almost every monitoring system you set up, whether for defense or
scientific purposes, if you don't want to be snowed with data, you in-
tentionally built selectivity in, and then you do not see what you are
not looking for.
Consequently, this point is important,that despite our many sensing
and monitoring systems, the fact that they don't repeatedly turn up
