A phenomenon is abroad in the land. Since shortly after the beginning of recorded history, but particularly during the past two decades, many people have reported visual observations of phenomena which they interpret as objects so intricate in their structure and proficient in their maneuvers that they far surpass the current human technology. The apparent objects are usually in the sky, but in a few cases they are on the ground or landing or taking off from the ground. Although they may not be flying and they may not be objects, they are called unidentified flying objects: UFO's for short.

What is the significance of these strange, typically aerial phenomena? There are many extremely important implications in the area of psychology. Perhaps the most obvious is the possibility that the UFO's may be purely psychological phenomena such as hallucinations. Of much greater importance, however, could be the psychological questions of interpretation. These are valid regardless of what elicits the response in the witness -- a real spaceship from Mars or a spotlight shining on a gossamer cloud.

The number of witnesses to these phenomena has increasedtremendously in recent years (probably a sizable fraction of 1% of the world's population has been involved in "good" sightings), therefore the phenomenon is of obvious sociological importance. It could influence the relationships between nations or programs of space exploration. It might even, given the proper circumstances, develop into a panic of severe proportions. There is ample justification from the sociological standpoint for a detailed study of the UFO phenomenon.

My interest developed from the field of exobiology. If the UFO's are extraterrestrial spaceships guided by intelligent beings (as many of their witnesses insist), then they are of the most pressing interest to the exobiologist. Current speculation about life on Mars (Jackson and Moore, 1965; Salisbury, 1962, 1966) would be naive indeed if such were the case. Although they would have virtually no significance to exobiology if they are not extraterrestrial, the possibility that they might be seems great enough to merit at least a preliminary investigation.

We might well consider the UFO's from the standpoint of the philosophy of scientific method. Even if the scientific community at large were sincerely interested in the study of the phenomena, it would encounter many difficulties in knowing what approach to take. UFO sightings are events which usually cannot be repeated. The astronomer may also witness such events, e.g., the flares on Mars (Salisbury, 1962; Ley, Willy and Werner Von Braun, 1960), but at least he is a trained observer, and none of his colleagues are likely to doubt his word. In the case of the UFO's, although many observers may be highly trained in certain aspects of contemporary modern life, few, if any, could claim much competence as carefully schooled UFO observers! Frequently, they are not trained to differentiate between observation and interpretation, and often there is a strong tendency for all but close friends to doubt their word. Here, then, is a phenomenon of nature which could, and should, be of extreme interest to the scientist. But it is a difficult one for even him to study. How do we study events which cannot be repeated and which are recorded only through the minds of observers who can scarcely resist the temptation to enlarge their stories and to intermingle the facts with their own interpretations and psychological responses ?

About all we can do at present is to evaluate the reports, although sufficient desire might make more than this possible (in the Exeter sighting described below, observers could have actually waited, fully equipped with high-speed cameras and other devices, for the return of the objects). Professor J. Alien Hynek (1966), the Director of the Observatory at Northwestern University, and for the past 18 years consultant to the Air Force in their study of UFO sightings, has often stated that to make progress we must accept the fact that the UFO's do exist -- as reports. The Air Force and several private groups have accumulated bulging files of these reports, containing everything from detailed interviews to the remnants of pancakes submitted by a witness who claimed he had received them from a space man! These reports and the many which will be obtained in the future (using hopefully better means of information gathering) are the data with which we must work, and the only data so far available. What can we do with them?

One obvious approach is to propose as many possible interpretations as can be devised and then to evaluate the data in terms of these hypotheses. The process will be a circular one, in which hypotheses are formulated on the basis of the data, and the data are then re-examined in terms of the hypotheses. In the following paragraphs, five hypotheses are discussed and then a few representative sightings are considered. The subject has been reviewed by several authors in book form, often competently, but virtually always with some degree of prejudice (for: Hall, 1964; Keyhoe, 1960; Lorenzen, 1962, 1966; Michel, 1958; Vallee, 1965; Vallee and Vallee, 1966 -- against: Menzel and Boyd, 1963).

Vaisseaux spatiaux extraterrestres ou autres machines

Although earlier observers usually interpreted the UFO's in terms of miraculous religious events, most UFO observers during the past 19 years have suggested that the objects which they observed were extraterrestrial spaceships.

Can we eliminate the spaceship hypothesis in any rigorous scientific manner? Logically one might think of two approaches: either we must show in each and every instance ever reported that the object was not an extraterrestrial spaceship, or we must show by some sort of scientific logic that it is impossible for extraterrestrial beings to visit us.

Obviously, we cannot show in every case that a purported UFO was not an extraterrestrial spaceship. The data may not be available, and the events cannot be repeated. Furthermore, in several instances, very detailed data do exist in relation to a sighting, and yet it cannot be rigorously stated that the UFO was not an extraterrestrial machine.

Nevertheless, this approach has been followed in an attempt to eliminate this hypothesis, notably by Professor Donald Menzel, Director of the Harvard Observatory (Menzel and Boyd, 1963) and by the United States Air Force. Menzel is aware of the logical limitations, but he takes a statistical approach. He reasons that since many sightings can be positively eliminated as extraterrestrial spaceships, those which cannot could be if only more data were available. This is an excellent example of the inductive form of reasoning which has been so productive in science. Can we confidently apply it in relation to the UFO phenomena? To do so, the cases for which ample data exist and which prove not to be spaceships must be representative of the class as a whole. To many of us this seems unlikely, since other cases fortified with considerable data cannot be eliminated as extraterrestrial machines, and in many ways they appear to have little in common with the cases which can. On purely formal grounds, then, we cannot be absolutely convinced by Menzel's approach.

It is also logically unreasonable to say with absolute certainty that it is impossible for extraterrestrial beings to visit us. Although we know a great deal about the universe, we do not yet know enough to make such an all-inclusive negative statement. Nevertheless, many of the arguments are highly compelling, and two are especially worthy of our attention. The first argument is that the UFO's contravene the laws of nature, or more properly, that they are contrary to our experience. It is first assumed that they could not originate within our solar system because only the earth harbors intelligent life, and then it is reasoned that because of the extreme distances between stars they could not be visitors from some other planetary system. My initial contact with the UFO problem came because of my doubts in relation to the first assumption (Salisbury, 1962; 1964; 1966).

Certainly we have no conclusive or even compelling evidence that Mars might support an intelligent civilization. We do, however, have a number of observations which seem to be in agreement with this assumption. The network of lines referred to as the canals still defies explanation in terms of nonintelligent phenomena, although such an explanation may well be apparent when we obtain more data about Mars. The satellites of Mars, with their almost perfectly circular, equatorial orbits and their small size have certain of the characteristics of artificial satellites. Brilliant flares of light occasionally seen on the surface of Mars are too short in duration and too bluish-white in spectral quality to be similar to our volcanoes, yet they are too long in duration to be readily explainable as meteorite impacts. An occasional associated white cloud would seem to eliminate them as reflections. It is even possible, if one is willing to stretch the imagination a bit, to find evidences [sic] for intelligence in the Mariner photographs of Mars. These ideas have recently been discussed in considerably more detail elsewhere (Salisbury, 1966).

There was an interesting correlation from 1948 to 1957 in the number of UFO sightings per unit time and the closeness to the planet Mars (Fig. 1). This was shown by Vallee and Vallee (1962; 1966) to be expected on statistical grounds less than one time in a thousand. Both Venus and Jupiter are far more prominent in the skies than Mars (both have often been misinterpreted as UFO's), and yet no such correlation exists with their apparent brightness in the skies and the number of UFO sightings.

New Guinea Event

Assuming that there is no intelligence on Mars and that the UFO's would have to cross interstellar space, can we really state with confidence that this is an impossibility? Do we know so much? Of course we do not. We are even searching for possible solutions to the problem of interstellar travel. Perhaps the roost compelling "impossibility" argument is the reported physical activity of certain UFO's (Menzel and Boyd, 1963). In several "good" sightings (those which, for reasons discussed below, do not readily fit any of the remaining four hypotheses), UFO's have appeared to accelerate at tremendous rates or even make right-angle turns while traveling at speeds of several hundred or thousand miles per hour. Although they move in the atmosphere at velocities which surely exceed that of sound, no sonic booms are heard (they are often essentially silent) nor do they appear to burn up with frictional heat. Le sceptique dit : Etant donné que nous avons encore beaucoup à apprendre de notre univers, nous ne nous attendons sûrement pas à ce que les lois fondamentales soient rejetées. Que nous puissions les affiner comme Einstein l'a fit, c'est vrai, mais l'inertie est l'interie, et un virage à angle droit à plusieurs milliers de miles par heure est une simple impossibilité physique.

This may be the most compelling argument against the spaceship hypothesis, but there are two counter-arguments. First, one can simply reject the above statement. I do not see how Newton's laws could be so flagrantly violated, but others (Lorenzen, 1962; Michel, 1958; Vallee and Vallee, 1966) have come up with various suggestions. Perhaps inertia is the gravitational interaction between an object and all other objects in the universe. If this gravitational attraction could some way be severed (some mysterious antigravity shield surrounding the spacecraft for example!), then right-angle turns at high speeds might be feasible. Would the surrounding antigravity field also nullify the sound barrier problem? Some think so. I haven't the faintest idea, but we could be wrong about what is impossible. Second, one might remember that not all UFO's perform "impossible" feats. The topic is sufficiently interesting if only one UFO proves to be a spaceship from Mars!

Another argument against the spaceship idea concerns the lack of formal contact with the UFO occupants. Since visiting spaceships ought to be piloted by some sort of intelligent beings, wouldn't it be reasonable to expect that they would desire contact with other intelligent beings, namely us? Or why hasn't a flying saucer landed on the United Nations Building to establish formal diplomatic relations?

This argument assumes that we can understand the motives of an extraterrestrial being. Of course we cannot. How could we know the minds of such beings? To inductively extrapolate from our own current sociological approaches to those of other intelligent. entities would be to commit the logical sin of extrapolation in a most flagrant manner. It is easy to imagine several reasons why the extraterrestrials might not want to contact us. Did they plant us here as a colony many thousands of years ago and are carefully observing our evolutionary development? Do they envy us for our natural resources and want to conquer us, although present logistic problems make such an effort impossible? Are they waiting for us to straighten out our wars and race problems? Are they simply uninterested in us as contemporaries, preferring to observe us as specimens? Entomologists study the honeybees very carefully but make no diplomatic contact with the queen!

Imagine the Aborigines of Central Australia, who are still in the stone age and who have not even developed the bow and arrow. They have had no contact at all with modern civilization. What happens when a jet plane flies overhead and one of them observes it? When he tells of the huge, shiny bird that didn't flap its wings, had no feet, made an ear-splitting roar, and even had smoke coming out of its tail, surely his fellows assume that he is crazy. Or if the phenomenon becomes so common that it must be accepted as real, they could hardly be expected to deduce from it the conditions of our modern civilization, let alone our motives. "Why," they might ask; don't the intelligent beings who guide this mighty bird land and trade bone nosepieces with us?" Actually, many of the Aborigines, even those who have come in contact with civilized men, still interpret the airplane in a religious context, as witness the establishment of the cargo cults among these peoples (Worsley, 1959).

We cannot, then, eliminate the spaceship hypothesis, although some of the arguments against it are quite impressive. We should, in deference to the scientific method, examine with a completely open mind any evidence which might be marshalled in favor of the hypothesis. Let us consider the four alternatives to it

Phénomènes conventionnels mal interprétés

Given certain special circumstances, nearly anyone can be confused and amazed by the appearance of some conventional object which under other circumstances might cause no bewilderment whatsoever. What psychological factors lead to such misinterpretations? In various instances, reported UFO's have clearly been demonstrated to be balloons, kites, birds, conventional aircraft, artificial satellites, planets and stars, meteors, clouds, natural electrical effects such as ball lightning (Klass 1966), and optical effects such as reflections, mirages, sundogs, and refractions caused by inversion layers in the atmosphere (see Menzel and Boyd, 1963, and Air Force files). Let us consider the level of certainty in classifying a given sighting here.

Often, the sighting may be placed here with absolute certainty. A balloon reported as a UFO was never out of sight of its launchers. A perplexing light in the sky takes form as an airplane as it gets closer.

My children woke me at 6:00 a.m. in Tubingen, Germany, saying that they were watching a hovering UFO over the city. I grabbed my binoculars and watched the brilliant light move rather rapidly both toward us and away from us and even from side to side. After about a minute, I decided to make my observations more precise, backed up against a doorway, and aligned the object with a spot on the window frame. Upon doing this, it stopped moving, and we were soon able to identify it as Venus, then the morning star. Its lateral motions were apparently illusions due to our own movements, and its rapid approach and retreat were due to a thin, rapidly moving layer of mists which caused it to change intensity.

Within the last year I have positively identified UFO's over Fort Collins, Colorado (pointed out to me usually by phone) as a weather kite, the planet Venus, and the stars Vega, Capella, Betelguese, and Sirius. Some of the stars close to the horizon flashed red, green, and white, and only a star chart and much discussion could convince the viewer that he was not observing a spaceship.

In many other cases, data are not quite complete enough to be positive, but one can state with a high degree of certainty that a given UFO was quite likely such and such a conventional object or phenomenon.

In the most interesting cases, the sighting seems absolutely to defy explanation in these terms.

One important conclusion becomes apparent: There is a very high noise level in UFO observations. This is exactly what one might expect. People do become excited by news stories and thereby predisposed to such experiences themselves. We cannot, however, from this high noise level write off the entire phenomenon as belonging to this category of conventional objects misinterpreted. Sagan (1963) attempted to do this by pointing out the great diversity which occurs within the sightings. This might well be only the noise. Even if spaceships are visiting us, many people are still seeing conventional objects and interpreting them as spaceships.

The sightings which do not fit well into the conventional-objects-misinterpreted category have certain characteristics concerned primarily with the detail which is observed and with the nature and reliability of the witnesses. Sometimes other evidence is also available.

If only a moving light is seen at a great distance, one can hardly be tempted to run out and meet our big brothers from Mars. Even a disc or a globe with fairly sharp-appearing edges might well be an optical effect of some sort. A report is more impressive when the object is seen at close hand, especially landed on the ground. A very distinct shape with highly distinct edges and a solid, often metallic-appearing surface is described. Windows or other markings may be apparent. Lights are frequently an associated part of the observation, and sometimes (both day and night) the brilliance was said to be so high that the observer found it difficult to continue looking at the UFO. Occasionally, one part of the UFO is described as being in motion relative to other parts, (The rim of a disc may be rotating around the disc.) "Occupants," both humanoid and otherwise, have been reported in conjunction with UFO's, landed and flying. The quality of a sighting is always enhanced when the time of observation is long enough for the observer to consciously consider what he is observing while he is observing it. A light that moves by in less than 5 seconds can hardly produce a very impressive account. In some cases UFO's have been observed for 1 or 2 hours or even longer.

We are primarily concerned with witnesses. Their background and training are especially important, and it is valuable when a single sighting is described by more than one witness. The likelihood of hoax is decreased if the witnesses were unknown to each other before the sighting.

In some cases an account may be supported by various forms of supplementary evidence. There are many cases in which photographs have been taken while a UFO was witnessed by several apparently competent observers. Holes have been left in the ground where a UFO had supposedly landed or vegetation has been damaged or on fire. Occasionally (rarely), radioactivity has been detected. In one case a fence was magnetized where a UFO had passed over it. Many strange samples have been left, such as Liquid residues, "angel's hair," and other materials.

In no case, of course, are these things by themselves conclusive, since virtually any sort of evidence could be fraudulently produced. We remain dependent upon the reliability of the witnesses, but sometimes these secondary evidences can contribute to an evaluation of the sighting.

Many radar sightings of UFO's are on file. In a few cases, a UFO has been simultaneously observed by radar and by witnesses, both on the ground and in an aircraft. Menzel and Boyd (1963) have clearly pointed out, however, that radar evidence is far from positive proof. There are many natural atmospheric and other phenomena as well as imperfections in radar instruments which can produce so-called radar angels. We must consider the argument from both sides, however. Just because radar angels are not necessarily UFO's, we are still not entitled to conclude that any unusual blip on the screen is a radar angel. We should certainly not conclude that UFO's cannot be extraterrestrial spaceships, because if they were, our radar net would pick them up. The fact of the matter is, our radar net does pick up many returns which are not identifiable in terms of known aircraft (e.g., apparent objects moving several thousand miles per hour through the atmosphere). Many of these are undoubtedly radar angels in the true sense of the word, but we can't say that some are not spaceships from Mars!

A secondary form of supporting evidence is that of pattern. While Sagan (1963) fails to see any pattern because of the noise, other investigators feel that many patterns can be established from the reports. Figure 1 (UFO's and Mars oppositions) is an example of such a pattern. Various other patterns have also appeared. Michel studied the sightings in France in 1954 and found that occasionally (Fig. 2) they appeared to fall upon great circle arcs of the earth's surface (Michel, 1958). It is extremely difficult (Menzel, 1964; Vallee, 1964) to evaluate the significance of such a pattern. In many cases, the lines could be due purely to chance. In the example illustrated, however, with six points upon a single line, one can't help but be somewhat impressed.

New Guinea Event

Circumstances of the 6 sightings on the line were very briefly as follows:

  1. Vichy, afternoon: Football players practicing in a stadium and spectators saw an elliptical, cigar-shaped object cross the sky swiftly and silently.
  2. Gelles, early night: The witnesses saw a luminous, cigar-shaped object cross the sky at fairly high speed and without noise.
  3. Ussel, about 11 p.m.: A luminous red object rose above the horizon and dived, at high speed, toward M. Cisterne, who was driving his tractor back to the barn. The object approached so closely that he jumped from the tractor and lay terrified in the field. The object hovered a few yards above the road, and in front of the tractor, remaining motionless for several minutes in complete silence. Surroundings were illuminated with a reddish light. The UFO then flew over the tractor and disappeared over the horizon in a few seconds. Two other people also saw the object, and leaves at the top of an ash tree, near where the object reportedly had hovered, were dried and curled.
  4. Tulle, 11 p.m.: M. Besse, with the aid of high-powered binoculars, watched a luminous object move rapidly in the sky, changing color from reddish to white and then to green.
  5. Lencouacq, nightfall: A single witness watched a luminous object arrive at high speed in silence, hover above a meadow, and then leave again at high speed.
  6. Bayonne, afternoon: Many people watched three elliptical objects, metallic in appearance, hover in the sky, and then move away very rapidly.

If all of these criteria are met for a given UFO report, then it is highly likely that we are not dealing with a conventional object misinterpreted. The detail usually precludes this. In such a case, the UFO could be an extraterrestrial spaceship or it could fit into one of the categories discussed below.

Phénomènes psychologiques

Can the UFO's be pure figments of the mind -- hallucinations, dreams, and the like? Probably there are cases for which this is the proper explanation, but it is a difficult one to apply to situations in which many witnesses describe with reasonable uniformity a single UFO. In such cases, the psychological explanation would have to fall back on areas such as extrasensory perception, which are really not much more respectable in modern science than spaceships from Mars. In cases in which radar observes the object at the same time that it is observed visually and/or it is photographed, we would have to postulate that one mind can project an object into the heavens in such a way that instruments such as radar and the camera detect it. This would be as exciting as spaceships!

Certainly we do not know all there is to know about the operation of the human mind, so this hypothesis cannot be completely eliminated. And even if the UFO's arc spaceships, psychological factors play an important part in the phenomenon. Nevertheless, this hypothesis is not really satisfying. Probably the most detailed study of the UFO's by a psychologist was carried out by Jung (1959). He was able to document a great many extremely fascinating psychological Implications of the UFO. In his final conclusion, however, he could only state that psychological explanations were not sufficient for the phenomenon as a whole.

Canulars ou mensonges

An obvious and straightforward explanation of the UFO's is that the witnesses are lying or that the object is a hoax. Yet the Air Force, always acutely aware of this possibility, explained only a very small percentage of the cases which they investigated in this way. Often it is very difficult to imagine that a hoax is involved. The witnesses give all of the outward signs of being extremely sincere: often they are emotionally upset by their recent experience. Frequently, their background and general competence seem to argue strongly against the idea of hoax. Furthermore, in sightings in which hundreds and even thousands of witnesses are involved (and a few such sightings are on record), one must reject the idea that all the witnesses were lying. If a hoax were involved, it would have to be the object itself.

Before completely eliminating this explanation, we must remember that a hoax can be amazingly effective. I saw the great Blackstone on a stage apparently pass a rapidly moving handsaw blade directly through the neck of an assistant in a trance. A block of wood below the neck was sawed in half amidst much noise and flying sawdust Yet this was admittedly a hoax. Would it be possible to some way cause an illusion in the sky which could completely fool hundreds of witnesses? I cannot absolutely say that it would not. On the other hand, in many cases, producing such an illusion would appear to be almost as great a feat as building a flying saucer itself.

One aspect of the UFO story does seem to be deeply involved in hoax. This is the so-called contactee cult. Many people now located over much of the world claim to have had direct contact with the flying-saucer people. (Adamski and Leslie, 1958; UFO International).

Perhaps the contactee is informed by mental telepathy that he should report promptly to a certain lonely spot in the desert. Upon obeying, he is met by a flying saucer whose occupants are, as a rule, beautifully humanoid and who. frequently take him into their confidence by allowing him to photograph themselves and their craft, inviting him in for a look at the control panels, and perhaps taking him for a quick spin, sometimes to Mars or Venus but best of all to the mysterious planet on the other side of the sun, unobservable from mother earth.

Everything about these stories seems to cry hoax. The proof is typically a series of photographs (which could easily be fraudulent) and copious quantities of pseudoscience. Someone who had really contacted visitors from another world should surely be able to do better than that. Why should visitors from another world bother with such obscure representatives of the human race, anyway? Their message is always that man must cease his wars or be destroyed, but why should such an important message be given to someone who is bound to be considered a liar when he delivers it?

It is interesting to consider the possibility that the contactees are genuine. When considering the UFO phenomenon, all sorts of wild alternatives come to mind. If the extraterrestrials wanted to be ignored by the scientific community on earth, they could hardly choose a better and more effective way than the delivering of profound messages to the souls who presently claim contact!

Armes secrètes

It is possible that secret devices being tested by earthly governments are misinterpreted as extraterrestrial machines. That this explanation might account for the phenomenon as a whole is, however, quite unreasonable. To begin with, the performances of the UFO's makes our present rockets appear puny indeed. Could any modern government suppress such a capability for nearly 20 years (since 1947)?

Most convincing is the fact that the UFO phenomenon goes way back into history. UFO enthusiasts, for example, often cite the first two chapters of the Book of Ezekiel in the Old Testament as an excellent example of a flying saucer sighting, (Menzel and Boyd, 1963, indicate that it was probably a sundog, but this is a far-fetched explanation for the details reported by Ezekiel.)

Vallee (1965) documents the sightings previous to 1947. He states that he has on file more than 300 UFO sightings prior to the 20th century, although he apologizes because he has never had the time to make a thorough search. He considers his cases to be only a small sample of those which might be available. They were carefully chosen for their high quality, roughly conforming to the criteria of good sightings described above. Some 60 of these 300 accounts occurred previous to 1800, and the remainder were recorded during the 19th century. The great majority of these more recent accounts were recorded in the scientific literature, particularly that of astronomy (often in the annals of the various astronomical observatories). It is important to emphasize that these are accounts which are not readily explainable as natural phenomena.

Classic, for example, are the observations in Nuremberg (14 avril 1561) and in Basale (August 7, 1566) which have been analyzed in some detail by Jung (1959). Both of these sightings involved large inclined tubes in the sky from which spheres originated, an event occurring sometimes in more recent times (Vallee, 1965, cites 13 examples between 1959 and 1964). Spheres and discs appeared to fight each other in aerial dances. The inhabitants of these two relatively large cities observed this strange phenomenon for a long interval of time on the dates given.

A great attempt was made to consider the scientific accounts of the 19th century in terms of the natural universe. They were referred to as interesting cases of ball lightning or bolide meteors. Nevertheless, the descriptions are of discs and wheels and the like, and the behavior follows very closely that of the modern UFO. These "meteors" would move slowly, appear to hover, change directions, accelerate at great speeds, have an apparent diameter two or three times that of the full moon, etc. In one instance, called ball lightning, an object slowly emerged from the ocean, moved against the wind, hovered close to the ship from which it was observed, and then rushed away in the sky and disappeared in the southeast (for details, see Vallee's book, 1965).

Sightings during the early part of this century were relatively few. The so-called Miracle of Fatima (Vallee, 1965; Walsh, 1947), which took place on October 13, 1917, in a field at Fatima, a small village some 62 miles north of Lisbon, Portugal, is a fascinating tale, to say the least. Today it would be considered a contactee story, since three children were supposedly contacted at monthly intervals (always on the 13th of the month), beginning in May, by a beautiful, "transparent" woman dressed in white, who arrived in a globe of light. Following the first visit, other witnesses besides the children observed strange events (a buzzing noise, etc.), but only the children saw the "vision." At the time of the miracle itself, some 70,000 people were gathered in the field by Fatima to wait for the promised sign. It had been raining when suddenly the "sun" appeared through the dense cloud cover. It was a strange sun, however, looking like a flattened disc with a very definite contour, not appearing as a dazzling object, but rather having a clear, changing brightness which one could compare to a pearl. The disc began turning, rotating with increasing speed as the crowd began to cry with anguish. It then began falling toward the earth "reddish and bloody, threatening to crush everybody under its fiery wake." After an interval of dancing before the crowd, it retreated back through the clouds and disappeared forever. It would be difficult to imagine a sighting which fits the above criteria better than this one. It is also difficult to imagine that the Fatima "sun" was a secret weapon being developed by Russia or the United States!

Bien que Vallée (1965) attire notre attention sur une vague fascinante d'observations en Scandinavie durant l'Eté de 1946, il n'arriva à personne à cette époque de les considérer comme des vaisseaux extraterrestres, mais comme des fusées secrètes développées par la Russie ou les Etats-Unis. Les observations actuelles remontent à celle de Kenneth Arnold. D'autres meilleures observations existent pour la même période, et même plusieurs jours avant (dès avril), mais Arnold a fait courrir son histoire dans les journaux, le terme "soucoupe volante" fut coined, et l'attention du monde fut focalisée sur le phénomène.

Arnold vit une formation de disques argentés volant d'un pic ou d'une arête à un autre autour du Mont Rainier dans l'état de Washington. En chronométrant le temp écoulé d'un répère au sol à un autre, il parvint à estimer leur vitesse à au moins 1200 miles/h. Menzel et Boyd (1963) "expliquent" l'observation d'Arnold par un mirage issu de couches d'inversion dans l'atmosphère qui fit apparaître les pics comme étant séparés des montagnes sous eux. Vraisemblablement, leur mouvement apparent serait dû au mouvement de l'avion d'Arnold. Une 2nde explication proposée par ces auteurs est que Arnold avait vu les nuages de forme lenticulaire qui surviennent parfois dans la région. Ils présentent des images de tels nuages (qui ressemblent exactement à des nuages en forme de lentilles et pas du tout aux objets décrits par Arnold). Ils jettent ensuite des aspersions sur la fiabilité d'Arnold comme témoin en décrivant en détails ses actions suivantes afin d'obtenir de la publicité, etc. Arnold est soutenu dans son histoire, cependant, par le fait qu'elle correspond exactement au schéma des observations de cette période. Divers auteurs (Hall, 1964 ; Lorenzen, 1962) ont compilé ces événements, et parmi ceci un thème récurrent est celui des formations de disques volants. De telles observations sont rares, ou essentiellement absentes, des signalements des années plus récentes.

Il est intéressant de se poser la question de combien d'apparitions de ce type ont été observées et non signalées. L'oncle de ma femme, M. Earl Page, alors résident de Kennewick (Washington), a observé le une formation de 6 ou 8 disques argentés dépasser son petit avion à une vitesse fantastique. Melle Page et son fils étaient présents et virent les objets, qui flottèrent en groupe pendant 1 s ou 2, puis se stabilisèrent... alternant entre ces 2 modes. Les Pages volaient vers le Nord au-dessus du Lac Utah. M. Page raconta son histoire à quelques amis qui se moquèrent de lui, et à partir de là n'en parla plus à personne.

Telle ou telle des observations de formations d'objets semblables à des soucoupes pendant l'été de 1947 pourraient peut-être être dismissed from the mind. Un grand nombre d'observations indépendantes, cependant, constituent un motif plutôt impressionnant.

Le cas de Chesapeake Bay, 14 Juillet 1952

Actions signalées des disques de la Baie de Chesapeake

Ceci est l'une des observations les mieux documentées dans les dossiers, impliquant des vitesses extrêmement élevées et un changement aigü de direction (fig. 3). Le 1er officier William B. Nash et le 2nd officier William H. Fortenberry pilotaient un vol commercial de New York à Miami, approchant Newport News (Virginie). A 20 h 12 (juste après l'obscurité) une lueur rouge brilliante apparut soudain à l'Ouest. Elle se révéla bientôt comme 6 objets en forme de pièce de monnaie volant en formation en ligne. Ils luisaient avec une couleur rouge-orangée brillante à leur sommet, et furent estimés à 100 pieds de diamètre et 15 pieds d'épaisseur. Ils se déplaçèrent rapidement vers l'avion, at one point breaking slightly in their perfect formation alors que les 2ème et 3ème objets wavered légèrement et dépassèrent presque le leader. Ils firent un virage à l'unisson sur la tranche et inversèrent leur position dans la formation, le dernier objet montant en première position et les autres le suivant. Ils inversèrent alors brusquement leur direction, moving off somewhat to the right avec à nouveau le leader d'origine en tête. Le virage fut exécuté presque comme des balles rebondissant sur un mur sans wavering ou arc apparents. 2 autres objets raced out de dessous l'avion et prirent des positions 7 et 8 dans la formation. Ils diminuèrent de brilliance juste avant de faire le virage ; les objets 7 et 8 étaient de loin les plus brillants alors qu'ils approchaient la formation ; et pendant 1 bref intervalle ou 2 l'ensemble des 8 arrêtèrent de clignoter puis s'illuminèrent à nouveau. Ils sped off, montant à une altitude supérieure à l'avion, puis 1 par 1 mais au hasard leurs lumières cessèrent de clignoter et l'observation fut terminée. En répétant leur observation mentalement, les pilotes estimèrent qu'elle n'avait duré que 12 à 15 s environ.

New Guinea Event

Menzel et Boyd (1963), après avoir considéré de nombreuses explications possibles pour l'observation, concluèrent que les pilotes devaient avoir vu les disques illuminés produits par un projecteur de recherche rouge brillant à travers des couches de brumes presque transparentes. Charles Maney (1965) correspondit avec Menzel pendant plusieurs mois, considerant toutes les explications possibles qui pourraient venir à l'esprit. Apparemment Menzel aurait facilement accepté plusieurs explications si Maney n'avait pas une par une clairement démontré leur non-plausibilité. Les pilotes eux-mêmes rejetèrent totalement l'hypothèse de Menzel du projecteur de recherche, indiquant qu'ils étaient familiers de tels phénomènes, et que ce n'était tout simplement pas ce qu'ils avaient observé. Les détails décrits ci-dessous sont certainement difficiles à réconcilier avec l'hypothèse de projecteur de recherche. La durée extrêmement courte de l'observation, cependant, pose la question de la précision absolue du récit. Certains points se sont-ils développés avec la discussion et le souvenir ? De plus, les vitesses des ovnis calculées entre 6000 et 12000 miles/h à travers l'atmosphère dense à 2000 pieds et incluant une inversion de direction instantanée, sont, pour dire le moins, extrêmement difficiles à accorder avec nos concepts actuels de l'univers. Des images de lumières peuvent effectuer ces manoeuvres, mais comment pourraient-être réaliser certaines des autres manoeuvres signalées par les 2 pilotes ?

Ce cas est présenté comme un exemple des problèmes rencontrés par un chercheur sur les ovnis. Résoudre une observation telle que celle-ci à la satisfaction de tout le monde nécessiterait de remonter dans le temps.

Ile de Trindade, 16 Janvier 1958

La Figure 4 montre une photographie prise par M. Almiro Barauna, un photographe professionnel, depuis le pont de l'Almirante Saldanha, un navire de la Marine Brésilienne. Plusieurs ovnis ont été vus dans le voisinage de l'Ile de Trindade (un possession brésilienne au large de la côte africaine) pendant sa réactivation comme base navale en relation avec l'Année Géophysique Internationale. Dans le cas rapporté ici, plusieurs marins aux extrémités opposées du navire repérèrent simultanément l'objet s'approchant et commencèrent à crier la nouvelle à tous les autres. Rapidement les quelques 100 marins à bord, dont divers officiers, se mirent à regarder l'objet. M. Barauna se préparait à prendre des photographie et avait son appareil prêt.

Les encarts sont des aggrandissements jusqu'au point de l'évidence du grain comme en Figure 4. Notez que l'objet apparaît sombre sur le fond, un effet impossible à obtenir par la technique habituelle de la double exposition. L'image pourrait avoir été prise et développée en la présence de témoins — bien qu'ils n'aient pas vu les objets !

Il prit 6 images, dont 2 ne purent montrer l'objet. Il expliqua qu'en raison de l'excitation il fut bousculé durant ces 2 là et qu'elles montraient seulement le point du navire et l'océan. Une chambre noire fut improvisée sous le pont, le film fut développé, et l'objet dessus fut identifié par les marins (Lorenzen, 1962).

Ceci est une excellente observation en raison du nombre de témoins impliqués et de l'excellente qualité des images (en particulière la troisième, celle montrée dans la figure). Des objets conventionnels peuvent difficilement expliquer l'observation.

Menzel et Boyd (1963) et apparemment l'United States Air Force considèrent l'observation comme un canular. Sur les hypothèses disponibles, seule celle-ci et celle de machines extraterrestres semblent pouvoir s'appliquer. L'explication du canular doit également probablement échouer si l'objet fut réellement observé par 100 marins. Menzel et Boyd racontent l'histoire différemment (leur version est basée sur un rapport d'amis astronomes de Menzel à Rio de Janeiro qui n'enquétèrent pas personnellement sur l'incident), indiquant que seuls Barauna et deux ou trois de ses amis proches déclarent avoir vu l'objet. Ceci bien que des journalistes aient interviewé les marins après que l'Almirante Saldanha accoste quelques semaines plus tard. J'ai reçu plusieurs rapports sur l'observation, dont une conversation personnelle avec le Dr. Alavio Fontes, un médecin de Rio de Janeiro qui enquêta sur le cas de manière approfondie. Ces rapports soutiennent complètement la version selon laquelle virtuellement tous les marins ont observé l'objet.

Evidemment, notre évaluation de l'histoire doit reposer sur cet aspect. Les photographies, bien que très convaiquantes, pourraient être frauduleuses. Pour prouver cela j'ai passé plusieurs jours à tenter de les reproduire et réussit assez bien comme indiqué en Figure 5. Nous restons avec la question de la véracité des témoins.

New Guinea Event

Driving home from a hunting trip, Mr. and Mrs. Arthur Strauch and their son Gary (age 16), and Mr. and Mrs. Donald Grew, all of Gibbon, Minnesota, sighted a hovering object and got out to observe it. Binoculars were used, and Mr. Strauch took one photograph on an 804 Instamatic Kodak camera using Ektachrome X film. The photograph is shown in Figure 6 along with an artist's conception of the sighting. The object moved toward the witnesses almost directly overhead, making a high-pitched whining sound and traveling at very high speed. It disappeared in the southeast within seconds.

Much detail was observed, several witnesses were present, ample time was available, a photograph was taken, and hence this instance meets the criteria nicely.

Socorro, Nouveau Mexique, 24 Avril 1964

New Guinea Event

Le patrouilleur Lonnie Zamora suivait un excès de vitesse lorsqu'il vit une flamme bleue au Sud-Ouest. Il reconnut la zone comme une contenant une remise à dynamite et où des adolescents essayaient parfois de de faire accélérer leurs voitures jusqu'aux steep slopes. He decided to investigate. Driving over a mesa (Fig. 7), he caught sight of something which he interpreted as an automobile standing on end with two children or small adults dressed in white clothing and standing by it. He radioed Patrolman Sam Chavez, asking for assistance, and continued down through a gully where he lost sight of the object. Coming up across the next mesa, he parked and got out of his car, moving toward the gully to see the object. It was immediately apparent that he was not observing an automobile wreck. There was a hemispherical object standing on four legs and suddenly an ear-splitting roar. Thoroughly frightened, he turned and ran, collided with the hood of his car, and then threw himself on the ground, noticing again that the object was rising in a slanting trajectory toward the southwest. As it rose, it displayed a blue flame.

Upon investigation of the site, four distinct, rather deep impressions were found in the ground where Zamora claims to have seen the landing gear. Two smaller round depressions were in the place where a ladder was placed, leading to a marking on the object which could have been a door. Bushes below where the object had been were burning. Detailed investigations were carried out by the Air Force and by several private flying saucer investigating groups.

The sighting is a good one in terms of detail and primary evidence. A landing with observed humanoid "occupants" is also of interest. It is bad in only one respect: namely, that Zamora was the sole witness (one or two leads appeared, but other witnesses could never be located), but his apparent sincerity was impressive. Investigators studied the surrounding area for tracks of possible perpetrators of a hoax but could find none, although the ground was soft. The sighting is typical of many similar reports, particularly in France and Brazil, but occasionally also in the United States.

Evénement de Nouvelle Guinée

Les observations furent semblables les 2 soirs. Le soir du 27, le père W. B. Gill, un enseignant et missionnaire de l'Eglise Anglicane en Nouvelle Guinée, sortit du réfectoire à 18 h 45, regardant en l'air et voyant Venus puis le grand objet scintillant. Alors qu'il regardait, quelques 39 autres le rejoignirent (5 étaient des enseignants, 2 étaient des aides médicales, les reste des indigènes ; 28 témoins adultes signèrent une déclaration). L'objet et 2 autres qui stationnaient à une grande distance sont montrés dans la figure (voir ci-contre) comme une vue d'artiste (les témoins n'avaient pas d'appareils photos mais firent des croquis au crayon durant l'observation). Alors que l'ovni stationnait à côté, des formes humaines apparurent sur le "pont supérieur" et semblaient travailler sur quelque chose. Occasionnellement, il y avait un fin rayon de lumière bleue brillante projeté vers le ciel. L'objet lui-même émanait de l'orange, et les "hommes" semblaient être vêtus en une sorte d'habits argentés. Le plus grand nombre vus en même temps était de 4. Lorsque l'une des figures sembla jeter un oeil sur la foule, Gill fit un signe du bras, et la figure lui retourna le même geste. Gill et certains des indigènes levèrent alors leurs bras, et 2 des figures sur l'objet firent de même. L'objet descendit mais n'atterrit pas. L'observation durant jusqu'à 7 h 20 lorsque le projecteur bleu disparut et que l'objet se déplaça dans un nuage.

Les témoins, the time, et les détails font de ceci une observation exceptionnellement bonne, une des meilleurs enregistrées. La seule explication disponible autre que le vaisseau spatial paraîtrait à quiconque un canular complexe perpétré par Gill et l'ensemble de ses associés.

Exeter (New Hampshire), 3 septembre 1965

Une observation remarquable eut lieu assez récemment dans le New Hampshire et fut étudiée et documentée par pluisieurs enquêteurs sur les ovnis mais en particulier par M. John G. Fuller, chroniqueur pour le Saturday Review. Il a assemblé des résultats sous forme d'un livre (Fuller, 1966), et un récit préliminaire fut publié dans le magazine Look (22 février 1966). Les observations sont remarquables non seulement en raison de leur nature mais au sens tout à fait réel en raison de l'enquête de M. Fuller.

Les observations de base eurent lieu aux premières heures du matin (entre 2 h 00 à 4 h 00 environ). Le patrouilleur Eugene Bertrand de Exeter had checked on a parked car and found a woman who told him that a huge and silent airborne object had trailed her from the town of Epping 9 miles away. The object had brilliant flashing red lights and kept within a few feet of her car. Developing tremendous speed, it had disappeared among the stars. The patrolman could not believe the story and had not even taken the woman's name.

When Bertrand checked into the police station, Norman Muscarello had just arrived and told his story. He had also seen a large dark object with brilliantly flashing lights hover above a field through which he had been walking on his way home. Patrolman Bertrand accompanied him back to the scene. Although nothing could be seen at first, horses on a nearby farm and dogs in nearby houses began making a great deal of noise, and then Muscarello screamed, "I see it, I see it!" Patrolroan Bertrand turned and observed the brilliant roundish object moving toward them like a leaf fluttering from a tree. Its red lights along the sides were so brilliant that the entire area was bathed in light. It came within about 100 feet of the two witnesses, hovering with a rocking motion, absolutely silent. The lights seemed to be dimming or pulsating from left to right and then from right to left, taking about 2 seconds for each cycle. The lights were so brilliant that it was difficult to make out the shape of the object itself. It darted, turned rapidly, slowed down, and performed other such maneuvers.

Patrolman David Hunt had heard the radio conversation between Bertrand and the station in Exeter and drove to the site, witnessing the object for a few minutes before it disappeared, A B-47 flew over shortly after, providing an extreme contrast to the object which they had previously witnessed.

In Fuller's study of the case, he was able to find some 60 different people who had witnessed similar objects over a period of several days or weeks in the fall of 1965. Muscarello was so impressed by his sighting that he and his mother waited on a mountainside nearly every evening for 3 weeks following the event. On one of these evenings, they again witnessed the object. Other people in the area would park by high tension lines (in the Exeter sightings, the objects were frequently associated with power lines) and watch for the objects, occasionally being rewarded with the sight of one.

This sighting is not only a good one because of the detail, the number of witnesses, and the several occasions involving comfortable intervals of time, but it adds one other extremely encouraging note. If Muscarello and other New Hampshire residents could go out and watch for the objects, occasionally being able to see them, why couldn't properly equipped scientific investigators do the same? Except for the Fatima incident, none of the other sightings have had much element of predictability. This may be simply because we have not taken the time or trouble to really look for it. Yet, it is not uncommon to find cases in which an object seen at one time returned on a later occasion (e.g., the New Guinea instance).

Serious scientific investigation of the phenomenon might be possible if it were desired by the scientific community. If a project could be set up by a number of scientists, it might be feasible to have everything in readiness for another wave of sightings such as that at Exeter or the subsequent one in the Michigan swamps. When such a wave appeared (and the proper kind of publicity might help in detecting it -- although it could also contribute to the generation of a wave of fraudulent sightings), the team of researchers might converge immediately upon the area and carry out some sort of previously planned program of investigation. If the investigators themselves were too busy to remain for periods of weeks to months, local people could be hired and trained in the proper techniques, Such a procedure might eventually reward us with the kind of tangible data with which science is used to dealing.
