In their public statements (but not necessarily in their private statements), scientists express a generally negative attitude towards the UFO problem, and it is interesting to try to understand this attitude. Most scientists have never had the occasion to confront evidence concerning the UFO phenomenon. To a scientist, the main source of hard information (other than his own experiments' observations) is provided by the scientific journals. With rare exceptions, scientific journals do not publish reports of UFO observations. The decision not to publish is made by the editor acting on the advice of reviewers. This process is self-reinforcing: the apparent lack of data confirms the view that there is nothing to the UFO phenomenon, and this view works against the presentation of relevant data. There are at least 4,000 humanoid cases (researched by Albert Rosales), also known as Close Encounters of the Third Kind (CE-III), a term coined by J. Allen Hynek. Humanoid" means "having human form or characteristics." The term "Close Encounter of the Third Kind" means seeing or coming in contact with an entity of unknown origin. The encounter may or may not be related to the sighting of an unidentified craft. The beginning of the modern era, 1947 brought us "Roswell" and other interesting happenings. But humanoids had been seen before and crashes mentioned also in previous years. Following is a list of known humanoid encounters for 1947. Some early UFO cases involving occupants, such as those in the ’50s and ’60s, involved more often than not creatures that resembled human beings in most respects. In the Grey-and-Reptoid-haunted 1980’s, 1990’s, and today, it is almost heretical to suggest that any other possible form of occupant can emerge from a UFO. But human ufonauts remain an intriguing part of the picture, and their very existence has suggested very disturbing possibilities to certain investigators. Effects of UFOs upon the principal sensory organs have been explored elsewhere. It was found, in brief, that the visual experience involved images of metallic vehicles, including various structural details, which were sometimes surrounded by vivid displays in brilliant colors or dazzling halos. A study of their noises disclosed several distinct types and suggested the artificial stimulation of auditory sensations within the head. Finally, several unique odors noticed in the vicinity of UFOs were traced to specific chemical compounds that are formed in the atmosphere under the stimulus of radiant energy that is emitted by UFOs. Reception of signals by the eyes, ears, and nose have been accounted for, yet there remains a variety of ways in which the body responds to UFOs at short range.
