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.

73 an unknown moving at speeds estimated at about 7000 mph. It is an interesting case, one that came to light for somewhat curious reasons. A low overcast pre- cluded any visual sightings from control tower personnel, so this is not a radar- visual case. I found no conventional explanation to account for it. It has to be stressed that there are many ways in which false returns can be seen on radarscopes, resulting not only from ducting of ground returns but also from interference from other nearby radars, from internal electronic signals within the radar set, from angels and insects (weak returns), etc. Hence each case has to be examined independently. After studying a number of official evaluations of radar UFO cases, I get the impression that there would probably be more radar Unknowns if there were less tendency to quickly explain them away by qualitative arguments that overlook pertinent quantitative matters. Even at that, there are too many conceded unknowns in official files to be ignored. A famous case in UFO annals involved a B-29 over the Gulf of Mexico, where several unknowns were tracked on the airborne scopes and were seen simul- taneously by crewmen, moving under the aircraft as they passed by (Refs. 4, 10, 25). This one is still carried as Unidentified in official files. Still another famous combined radar-visual case, which Hynek has termed "one of the most puzzling cases I have studied," occurred between Rapid City and Bismarck on August 5, 1953. It involved both ground and airborne radar and ground and airborne visual sightings, but is far too long and complex to recapitulate here. Perhaps the above suffices to indicate that UFOs are at times seen on radar and have been so seen for many years. The question of why we don't hear a great deal about such sightings, especially with newer and more elaborate surveillance radars, is a reasonable question. Some of the answers to that one are posed by the statement of Dr. Robert M. L. Baker, Jr., in these proceedings. Other parts of the answer must be omitted here. WHY AREN'T THERE NUMEROUS PHOTOS OF UFO'S IF THEY REALLY EXIST? Here is a question for which I regard available answers as still unsatis- factory. I concede that it does seem reasonable to expect that there should, over the past 20 years, be substantially more good photos than are known to exist. Although I do not regard that puzzle as satisfactorily answered, neither do I think that it can be safely concluded that the paucity of good photos disproves the reality of the UFOs. Many imponderables enter into consideration of this question. 1. Some general considerations If one had reliable statistics on the fraction of the population that carried loaded cameras with them at any randomly selected moment (I would guess it would be only of the order of one per cent) and had figures bearing on the proba- bility that a UFO witness would think of taking a photo before his observation terminated, then these might be combined with available information on num- bers of sightings to attempt crude estimates of the expected number of UFO photos that should have accumulated in 20 years. Then one would need to weight the data for likelihood that any given photo would find its way to some- one who would make it known in scientific circles, and then this figure might be compared with the very small number of photos that appear to stand the test of the exceedingly close scrutiny photos demand. A general rule among serious UFO investigators with whom I have been in touch is that the UFO photo is no better than the photographer (Hall). Many hoax photos have been brought forth. A UFO photo can be sold; this attracts hoax and fraud to an extent not matched in anecdotal accounts. Many photos have been clearly established as fraudulent in nature; far larger numbers seem so suspicious on circumstantial grounds that no serious investigator gives them more than casual attention. An interesting, even if very crude check on the likelihood of securing photos of UFOs from the general populace is afforded by fireball events. On April 25, 1966, a fireball rated at about magnitude —10, arced northward across the northeastern U.S. From the total geographic area over which this fireball was visually detected, the population count is about 40 million persons. According to one account (Ref. 43), 200 visual accounts were turned in, and I infer that only 6 photos were submitted. The fireball was visible for a relatively long time as meteors go, about 30 seconds, and was, of course, at a great altitude (25 to 110 km). That 6 photos were submitted (at time of publication of the cited article)
