VALLEE/MICAP/PARANET CLASSIFICATION AND RATING SYSTEM In order to encompass the full range of phenomena one finds in the modern literature, it is important to acknowledge that UFOs are related in significant ways to other anomalies. It is the rule, rather than the exception, to find significant UFO sightings preceded or followed by other anomalies, notably the poltergeist variety. The following classification scheme, created by Dr. Jacques Vallee, is being adopted by ParaNet and MICAP. AN Rating - ANOMALY - These do not specifically deal with UFO Reports: AN1 - are anomalies that do not have lasting physical effects, such as amorphous lights or unexplained explosions. AN2 - are anomalies with lasting physical effects, such as some poltergeist phenomena, apports (materialized objects), and areas of flattened grass. AN3 - are anomalies with associated entities. This class could include reports of ghosts, yetis, and other instances of cryptozoology as well as elves and spirits. AN4 - are those anomalous reports in which witnesses experienced personal interaction with entities in the reality of the entities themselves. They include near-death experiences, religious miracles and visions, and many cases of out-of-body experiences. AN5 - are those anomalous reports of injuries or deaths, such as spontaneous combustion or unexplained wounds. Also, cases of permanent healing often described in the literature of the paranormal. MA Rating - MANEUVER - are best classified according to the apparent behavior of the object rather than the circumstances independent of it, such as daylight or night, or radar rather than visual observation: MA1 - gathers those UFO observations that involve an object with a discontinuous trajectory (such as drop, a maneuver, or a loop). MA2 - includes those cases that give rise to physical effects in addition to a discontinuous trajectory. MA3 - contains the cases of objects with discontinuous trajectories when beings are observed on board. Some of the "airship" cases of the late nineteenth century were in this category, as well as the famous 1959 sighting by Father Gill of New Guinea. MA4 - covers instances of maneuvers accompanied by a sense of transformation of reality for the percipient. MA5 - is a maneuver as a result of which the witnesses suffer permanent injury or death. FB Rating - FLY-BY: FB1 - is a simple sighting of a UFO "flying by" in the sky, the category most frequently reported. FB2 - is a flyby accompanied by physical evidence. FB3 - is a flyby of an object accompanied by the observation of beings on board. Although rare, this type of observation is reported occasionally. FB4 - is a flyby where the witness experienced a transformation of his or her reality into the object or its occupants. FB5 - would be a flyby as a result of which the witnesses would suffer permanent injuries, as in the celebrated Cash-Landrum case in Texas, which can be found in the literature. In that case, two women and a boy were hurt by the effects of a bright object that flew above them without landing or stopping. CE Rating - CLOSE ENCOUNTERS: CE1 - is a report where the object comes within 500 feet of the observer, but no interaction is involved with the observer or the environment. CE2 - is a report similar to CE1, however it leaves a physical record of its visit in the form of landing traces. CE3 - is a report where one or more animated entities are present in proximity to an UFO. The term "animate" is not used to allow for the possibility of robots or something other than "flesh and blood." CE4 - is a report that encompasses the "abduction" report, where the witnesses report extensive contact and physical interaction with the entities inside their craft. CE5 - is a report that involves CE4, with additional permanent physiological injuries, effects or subsequent death. THE SVP CREDIBILITY RATING NO classification system is complete without a way of assigning credibility or "weight" to an observation. Using a three digit code to indicate the weight of a UFO case, it can be determined how credible the report is using source reliability, site visit and possible explanations. first digit: source reliability (S): 0 Unknown source or unreliable source 1 Report attributed to a known source of uncalibrated reliability 2 Reliable source, secondhand 3 Reliable source, firsthand 4 Firsthand personal interview with the witness by a source of proven reliability second digit: site visit (V): 0 No site visit, or answer unknown 1 Site visit by a casual person not familiar with such phenomena 2 Site visit by persons familiar with such phenomena 3 Site visit by a reliable investigator with some experience 4 Site visit by a skilled analyst third digit: possible explanations (P): 0 Data consistent with one or more natural causes 1 Natural explanation requires only slight modification of the data 2 Natural explanation requires gross alteration of one parameter 3 Natural explanation requires gross alteration of several parameters 4 No natural explanation possible, given the evidence A rating of 222 or better (meaning that each of the three digits is two or higher), indicates the events reported through a reliable source in which a site visit has been made and where a natural explanation would require the gross alteration of at least one parameter.
