Documents / Hearing transcript
This is the printed transcript of an April 5, 1966 hearing of the U.S. House Committee on Armed Services on unidentified flying objects. Air Force Secretary Harold Brown testified that 9,501 of 10,147 sightings from 1947 through 1965 had been identified and that no threat or extraterrestrial evidence had been found. The record includes the Scientific Advisory Board ad hoc committee report recommending university studies and the Air Force's marsh gas explanation for the Dexter and Hillsdale, Michigan sightings. Members also questioned J. Allen Hynek and Maj. Hector Quintanilla about the Exeter, New Hampshire case.
6007 many of us firmly believed that, like some fad or craze, it would subside in a matter of months. Yet in the last 5 years, more reports were submitted to the Air Force than in the first 5 years. Despite the seeming inanity of the subject, I felt that I would be derelict in my scientific responsibility to the Air Force if I did not point out that the whole UFO phenomenon might have aspects to it worthy of scientific attention. What we have here is a signal-to-noise ratio problem: There is indeed a fantastic amount of noise, represented by the many misidentifications of familiar objects seen under unusual or surprising circumstances—balloons, birds, satellites ' meteors, air- craft, stars—yet, in all scientific honesty, one is led to ask whether there might not indeed be a signal somewhere in the noise. As a scientist, I must be mindful of the lessons of the past; all too often it has happened that matters of great value to science were over- looked because the new phenomenon simply did not fit the accepted scientific outlook of the time. Thus, the evidence of fossiles for biologi- cal evolution was overlooked; X-rays were overlooked, meteorites were overlooked as astronomers steadfastly refused to accept stories of stones which fell from the sky. Therefore, I have set aside for further study some 20 particularly well-reported UFO cases which, despite the character, technical com- petence and number of the witnesses, I have not been able to explain. I have done this to illustrate that neither I nor the Air Force hide the fact there are unexplained reports, and to illustrate also that the Air Force does not maintain, contrary to some public opinion, that re- porters of UFO's are lacking in intelligence or are objects fit only for ridicule. For of these reports, 10 are from scientists and highly trained indi- viduals, 5 are from members of the Armed Forces and members of the police force, and 5 are reports made by reliable American civilians. In my view, the reliability of the observers was above average in all 20 cases. The recent cases in Michigan have not been included in this particular collection since I feel that they are subject to simple, albeit somewhat unusual, explanation. I cannot prove beyond doubt that this is the case, but these two now famous reports illustrate the method the Air Force has used with great success in finding logical explanations for the great majority of the reports. We have used as a working hypothesis, when first confronted with a report, that a conventional explanation existed, either as a misiden- tification or an otherwise well-known object or phenomenon, a hallu- cination, or a hoax. This has been a very successful and productivehypothetsis. One must be aware, however, that complete adherence to one hypothesis may turn out to be a roadblock in the pursuit of research endeavors. As the saying goes, "If one digs too intently for coal he is apt to miss diamonds." Scientists should never be guilty of poverty ofhypotheses. And in dealing with the *truly puzzling cases, we have tended either to say that, if an investigation had been pursued long enough, the misidentified object would have been recognized, or that the sighting had no validity to begin with. The UFO public, on the other hand, is equally prone to poverty of hypotheses: Either UFO's mean utter bilge and nonsense, or they
