Vapor trails will often appear to glow with fiery red or orange streaks when reflecting sunlight. After burners are frequently reported as UFOs. 7 The astronomical category includes bright stars, planets, comets » meteors, and other celestial bodies. When observed through haze, light fog,. or moving clouds, the planets Venus, Mars, and Jupiter have often been reported as un- conventional, moving objects. Attempts to observe astronomical bodies through hand-held binoculars under adverse sky conditions have been a source of many UFO reports. i The "other" category includes reflections, searchlights, birds, kites, blimps, clouds, sun-dogs, spurious radar indications, hoaxes, firework dis- plays, flores, fireballs, ice crystals,bolides, etc., as examples: large Canadian geese flying low over a city at night with street lights reflecting off their bodies; searchlights playing on scattered clouds, appearing as moving disc-like shapres. t The insufficient data category includes all sightings where essantial or . pertinent items of information-are. missing, making it impossible to form a” - : valid conclusion. These include corroboration of the sighting by an additional‘ witness; description of the size, shape or color of the object; direction and altitude; exact time and location; wind weather conditions, etc. This category is not used as a convenient way to get rid of what might be referred to as . "unidentified objects." However, if.there is not an additional witness or ir* the data received is insufficient or unrelated, the analysts must then place *” that particular report in this category.

Project Biue Book Special Report #14, covered UFO investigations from June 1947 to May 1955. Since that time, Air Force statistics show the percentage of unidentified sightings has been reduced to approximately 2 percent. e Air Force conclusions for*the thirteen years of UFO sightings involving over 6,500 reports are: first, there is no evidence that unidentified sightings were inimical or hostile; second, there is no evidence that unidentified sight- ings were interplanetary space ships; third, there is no evidehce that these unidentified sightings represented technological developments or principles outside the range of our present day scientific knowledge; fourth, there is no evidence that these unidentified sightings are a threat to the security of the Approved For Release 2004/03/26 : CIA-RDP81R00560R000100040013-4 = -he oe MO]
