This document is the National Academy of Sciences panel review of the University of Colorado report on unidentified flying objects, copyrighted 1969 and filed as an attachment in an Office of the Secretary of Defense release. The panel, chaired by Gerald M. Clemence, judged the study's scope adequate and its methodology sound. It concurred that further extensive UFO study is not justified and that extraterrestrial visitation is the least likely explanation. A directory listing of UFO organizations such as NICAP and APRO is appended.

or man-made ;:ilenomena, twelve provided insufficient data for analysis,
and seven were considered to be possible fabrications; none proved to
be "real objects with high strangeness.")
Technically trained personnel were utilized by the University.
The University group included a sub-group on field investigations of
UFO reports; their narration and interpretations of cases are reasonable
and adequate. Leading groups were engaged under contract for specialized
work -- e.g., Stanford Research Institute on radar anomalies and a subsidiary
of the Raytheon Corporation for photogrammetric analyses. Divergent
views of those few scientists who have looked into UFOs were taken into
account. The history of the subject was also surveyed, including the
experiences in some other nations. Finally, extensive use was made
of many specialists in various public and private laboratories.
The Report makes clear that with the best means at our disposal, positive
correlation of all UFO reports with identifiable, known phenomena is
not possible. No study, past, current or future, can provide the basis
for stating categorically that a familiar phenomenon will necessarily
be linkable to every sighting. The Report is free of dogmatism
on this matter. It is also clear, as one goes through the
descriptions of UFO sightings, whether in the Report or in other literature,
that while some incidents have no positive identification with familiar
phenomena, they also have no positive identification with extraterrestrial
visitors or artifacts.
We think the methodology and approach were well chosen, in accordance
with accepted standards of scientific investigation.
III. FINDINGS
The study concludes (a) that about 90 percent of all UFO reports
prove to be quite plausibly related to ordinary phenomena, (b) that
little if anything has come from the study of UFOs in the past 21 years
that has added to scientific knowledge, and (c) that further extensive
study of·UFO sightings is not justified in the expectation that science
will be advanced thereby. At the same time it is emphasized in the
Report that (c) is an opinion based on evidence now available.
The Report's findings and evaluations -- essentially eight !n number,
presented in its first section -- are concerned with official secrecy
on UFOs, UFOs as a possible defense hazard, the future governmental
handling of UFO-sighting reports, and five of them relate to the question
of what if any further investigation of UFOs appear warranted in the
light of the study. We paraphrase and summarize these findings and·
evaluations be:ow, appending our comments.
1. On secrecy. Is the subject "shrouded in official secrecy"?
The study found no basis for this contention.
We accept.this finding of the study.
