“Rarity has nothing to do with reality.’ (V.A. Firsoff, a modern leading 
  astronomer).
  It is now not as hard as formerly to discuss 
  Ufology with the public today, there are more open-minded people who are 
  finally aware that something is occurring in our skies, than there were a 
  decade ago.
  
  It is no longer necessary to convince average people of the existence of these 
  craft; the main objections to overcome are the typical questions: “Why don’t 
  they contact our leaders?” and “How can they come here from another inhabited 
  planet, given the enormous distances, and the probability that the speed of 
  light may be the greatest possible velocity attainable?”
  
  Of course, these questions must remain unanswered for the time being. We are 
  faced with the fact of their presence in our environment; how they got here, 
  is a matter that is useless to toss around, for no one knows the answers.
  
  What is very important, is their motives for such an invasion of our air 
  space. And here, I am obliged to refer readers to a most impressive book by 
  A.L. Webre and P.H. Liss, called The Age of Cataclysm (Sanford J. Greenburger 
  Associates, 757 Third Avenue, New York; 1974; Berkley Medallion Books, New 
  York; 1975); for, in part II, section 2, of this most sober, and sobering, 
  book on earthquakes, one finds a section surprisingly devoted to the activity 
  of higher intelligent powers in our environment, which manifest themselves by 
  means of UFO sightings, by the production of advanced psychics, and also by 
  apparitions of figures interpreted as being the Blessed Virgin Mary — all in 
  locations that are close to the trajectories of the UFOs.
  
  This book is of extreme importance, and should be perused carefully by every 
  reader possessed of intellectual curiosity.
  
  At first, I was of the opinion that the Ufonauts were simply curious visitors 
  from another solar system. I wish this were the whole story; but it isn’t. 
  There seems to be much more to all this, as will become plain to anyone who 
  delves into the vast amount of published evidence, and who interviews the 
  thousands of witnesses: it would appear that someone, from somewhere, is 
  carrying out a reconnaissance, — a constant, but now an intensified, 
  monitoring of the human race and its environment;
  
  Samples of minerals, flora, fauna and humans (as well as animal blood in 
  quantities), are being regularly taken away by the beings, mostly along 
  certain straight-line trajectories that encircle the globe; and many of the 
  witnesses are displaying symptoms indicative of mental or psychological 
  tampering — while a few are even dying in mysterious ways.
  
  Often, UFOs are seen during freak lightning storms; and a great number of 
  electrical black-outs have occurred, just as unidentified strange-looking 
  craft were sighted passing over those vicinities.
  
  It has also been noticed, over the years, that the UFOs show an interest in 
  reservoirs and freshwater lakes, radio antennae, electric power transmission 
  lines, ancient burial mounds and modern cemeteries, and school playgrounds 
  where children are congregated.
  
  Moreover, the UFO that was seen by three nurses at a window of the Cowichan 
  District Hospital in Duncan, B.C., one New Year’s Day some five or six years 
  ago, was concentrating on what was happening in the children’s ward, according 
  to one of the nurses whom I interviewed.
  
  What is, for me, possibly the most worrying aspect of the phenomenon, is the 
  frequency of witnesses’ reports wherein a significant time-lapse occurred, 
  during which the witnesses seem to have been in a total unconsciousness (or 
  trance?); often, such cases have become known (as, especially, in the Hills’ 
  case, in New Hampshire) as a direct result of the sudden and repeated 
  nightmares suffered subsequently by the witnesses, who felt led thereby to 
  consult psychiatrists; the latter uncovered the incidents from the memories of 
  the patients, by using hypnosis techniques.
  
  Of course, hypnosis is not completely reliable in such cases; but the very 
  frequency of similar cases from every country, cannot but indicate that the 
  reports were by no means imaginary.
  
  It is, to me, the mental or psychological effects in certain witnesses that 
  apparently contain a most important clue. It is believed that if a person is 
  subjected to a strong electro-magnetic force-field, his SSP (suprasensory 
  perception, known less correctly as ESP) will be triggered artificially; in 
  fact, Dr. Karlis Osis has published some announcements of work that is being 
  conducted precisely in this area.
  
  The UFOs seem to be surrounded by such a force-field, for they have on 
  countless occasions stalled the motors of cars (but seldom of diesel engines), 
  extinguished the headlights and radios, and even drained the batteries, 
  leaving the tops of these sometimes in an almost liquid condition.
  
  Some witnesses even reported that metal objects, such as the rings on their 
  fingers, became intolerably hot, until the UFO sped off. Train crews (e.g. on 
  B.C. Rly., C.N. Rlys., & C.) have repeatedly reported that the presence of a 
  UFO impeded radio communication between locomotive and caboose.
  
  Thus, it could be inferred that, when a witness displayed certain symptoms of 
  clairaudience, of clairvoyance, or of telepathy (i.e. psychic, or SSP powers), 
  this might be a by-product of a force-field surrounding an unidentified craft 
  in the general vicinity.
  
  (There have been occasions when, apparently, a UFO switched off this 
  force-field, and hence no effect was noted on cars’ engines, etc. This has 
  usually been concurrent with reports of soundless craft, as compared with 
  craft that emitted a buzzing or other kind of sound).
  
  In areas of concentrations of sightings and landings, some people have 
  reported psychic phenomena occurring at the time of the UFOs’ visits, and 
  poltergeist infestations in some houses have occurred with some frequency, at 
  such times and in such places.
  
  It has even been reported that, where UFO ‘flaps’ have occurred (i.e. 
  concentrations of sightings and landings in an area), a few people displayed 
  an abnormal rise in their I.Q., whereas certain other people appeared to be 
  displaying something resembling symptoms of demonic possession.
  
  Although no one knows the real cause of all this, it is possible to hazard a 
  guess that it could all boil down to electromagnetic fields of force acting 
  upon the psyche. A great deal of research is needed in this area.
  
  For this reason, investigators have had to concern themselves seriously with 
  the matter of tampering with people’s brains: is it accidental, a mere 
  by-product of the force-field, or can it be deliberate? If deliberate, this 
  could mean they are meddling with our affairs, and manipulating us for reasons 
  of their own. This might have serious consequences for the whole planet: 
  political sociological and even religious.
  
  A reader may at this point prefer to scoff; uninformed as he may be, this is 
  only natural. However, I should warn him that I, too, used to be a scoffer, 30 
  years ago. It was not until one of my professors rebuked me for my ignorant 
  skepticism, that I decided I had better look into the phenomenon – if only so 
  as not to make a fool of myself, by making foolish objections.
  
  The attitude of a properly educated person in the face of the unexplained 
  should surely be that of enquiry, not of ungrounded and ignorant skeptical 
  rebuttal: comparatively recently, a leading British Astronomer-Royal stated 
  that the very idea of space-travel was “utter bilge”.
