[BLANK] reported disc saucer observation — May 1955

Air Force program that investigated unidentified flying objects (UFOs). This study was undertaken primarily to categorize the available reports of sightings and to determine the probability that any of the reports of unidentified aerial objects represented observations of "flying saucers". In order to establish the probability that many of the reports of unidentified aerial objects represented observations of "flying saucers", it was necessary to make an attempt to answer the question "What is a 'flying saucer'?". However, it must be emphasized that this was only incidental to the primary purpose of the study, the determination of the probability that any of the reports of unidentified aerial objects represented observations of "flying saucers", as defined on Page 1. The text on the page describes various cases related to unidentified flying objects (UFOs). Each case discusses the characteristics and features of the reported UFO sightings. The text discusses the various conditions that the UFO cases do or do not satisfy, and provides details about the observed objects, such as their shape, presence of protrusions, rocket or jet pods, fins or rudders, and series of portholes or windows. (12) Case XII. It is not possible, therefore, to derive a verified model of a "flying saucer" from the data that have gathered to date. Out of about 4,000 people who said they saw a "flying saucer", sufficiently detailed descriptions were given in only 12 cases. Having culled the cream of the crop, it is still impossible to develop a picture of what a "flying saucer" is. In addition to this study of the good UNKNOWNS, an attempt was made to find groups of UNKNOWNS for which the observed characteristics were the same. On the basis of this evidence, therefore, there is a low probability that any of the UNKNOWNS represented observations of a class of "flying saucers".
