Ruppelt</a>, by the end of 1951, several high-ranking, very influential USAF generals were so dissatisfied with the state of Air Force UFO investigations that they dismantled Project Grudge and replaced it with Project Blue Book in March 1952. One of these men was Gen. <a href="/wiki/Charles_P._Cabell" title="Charles P. Cabell">Charles P. Cabell</a>. Another important change came when General <a href="/w/index.php?title=William_Garland_(Air_Force_Officer)&amp;action=edit&amp;redlink=1" class="new" title="William Garland (Air Force Officer) (page does not exist)">William Garland</a> joined Cabell's staff; Garland thought the UFO question deserved serious scrutiny because he had witnessed a UFO.<sup id="cite_ref-swords103_5-0" class="reference"><a href="#cite_note-swords103-5"><span class="cite-bracket">&#91;</span>5<span class="cite-bracket">&#93;</span></a></sup> </p><p>The new name, Project Blue Book, was selected to refer to the blue booklets used for testing at some colleges and universities. The name was inspired, said Ruppelt, by the close attention that high-ranking officers were giving the new project; it felt as if the study of UFOs was as important as a college final exam. Blue Book was also upgraded in status from Project Grudge, with the creation of the <a href="/w/index.php?title=Aerial_Phenomenon_Branch&amp;action=edit&amp;redlink=1" class="new" title="Aerial Phenomenon Branch (page does not exist)">Aerial Phenomenon Branch</a>.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">&#91;</span>6<span class="cite-bracket">&#93;</span></a></sup> </p><p>Ruppelt was the first head of the project. He was an experienced airman, having been decorated for his efforts with the Army Air Corps during <a href="/wiki/World_War_II" title="World War II">World War II</a>, and having afterward earned an aeronautics degree. He officially coined the term "Unidentified Flying Object", to replace the many terms ("flying saucer", "flying disk" and so on) the military had previously used; Ruppelt thought that "unidentified flying object" was a more neutral and accurate term. Ruppelt resigned from the Air Force some years later and wrote the book <i>The Report on Unidentified Flying Objects</i>, which described the study of UFOs by the United States Air Force from 1947 to 1955. American scientist <a href="/wiki/Michael_D._Swords" title="Michael D. Swords">Michael D. Swords</a> wrote that "Ruppelt would lead the last genuine effort to analyze UFOs".<sup id="cite_ref-swords102_7-0" class="reference"><a href="#cite_note-swords102-7"><span class="cite-bracket">&#91;</span>7<span class="cite-bracket">&#93;</span></a></sup> </p><p>Ruppelt implemented a number of changes: He streamlined the manner in which UFOs were reported to (and by) military officials, partly in hopes of alleviating the stigma and ridicule associated with UFO witnesses. Ruppelt also ordered the development of a standard questionnaire for UFO witnesses, hoping to uncover data that could be subject to statistical analysis. He commissioned the <a href="/wiki/Battelle_Memorial_Institute" title="Battelle Memorial Institute">Battelle Memorial Institute</a> to create the questionnaire and computerize the data. Using case reports and the computerized data, Battelle then conducted a massive scientific and statistical study of all Air Force UFO cases, completed in 1954 and known as "<a href="#Project_Blue_Book_Special_Report_No._14">Project Blue Book Special Report No. 14</a>" (see summary below). </p><p>Knowing that factionalism had harmed the progress of <a href="/wiki/Project_Sign" title="Project Sign">Project Sign</a>, Ruppelt did his best to avoid the kinds of open-ended speculation that had led to Sign's personnel being split among advocates and critics of the <a href="/wiki/Extraterrestrial_hypothesis" class="mw-redirect" title="Extraterrestrial hypothesis">extraterrestrial hypothesis</a>. As Michael Hall writes, "Ruppelt not only took the job seriously but expected his staff to do so as well. If anyone under him either became too skeptical or too convinced of one particular theory, they soon found themselves off the project".<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">&#91;</span>8<span class="cite-bracket">&#93;</span></a></sup> In his book, Ruppelt reported that he fired three personnel very early in the project because they were either "too pro" or "too con" one hypothesis or another. Ruppelt sought the advice of many scientists and experts, and issued regular <a href="/wiki/Press_releases" class="mw-redirect" title="Press releases">press releases</a> (along with classified monthly reports for military intelligence). </p><p>Each U.S. Air Force Base had a Blue Book officer to collect UFO reports and forward them to Ruppelt.<sup id="cite_ref-Blum_9-0" class="reference"><a href="#cite_note-Blum-9"><span class="cite-bracket">&#91;</span>9<span class="cite-bracket">&#93;</span></a></sup> During most of Ruppelt's tenure, he and his team were authorized to interview any and all military personnel who witnessed UFOs and were not required to follow the <a href="/wiki/Chain_of_command" class="mw-redirect" title="Chain of command">chain of command</a>. This unprecedented authority underlined the seriousness of Blue Book's investigation. </p><p>Under Ruppelt's direction, Blue Book investigated a number of well-known UFO cases, including the so-called <a href="/wiki/Lubbock_Lights" title="Lubbock Lights">Lubbock Lights</a>, and a widely publicized 1952 radar/visual case over <a href="/wiki/Washington_D.C." class="mw-redirect" title="Washington D.C.">Washington D.C.</a> According to <a href="/wiki/Jacques_Vall%C3%A9e" title="Jacques Vallée">Jacques Vallée</a>,<sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">&#91;</span>10<span class="cite-bracket">&#93;</span></a></sup> Ruppelt started the trend, largely followed by later Blue Book investigations, of not giving serious consideration to numerous reports of UFO landings and/or interaction with purported UFO occupants. </p><p>Astronomer <a href="/wiki/J._Allen_Hynek" title="J. Allen Hynek">J. Allen Hynek</a> was the scientific consultant of the project. He had been with Projects Sign and Grudge. He worked for the project up to its termination and initially created the categorization which has been extended and is known today as <a href="/wiki/Close_encounter" title="Close encounter">Close encounters</a>. He was a pronounced skeptic when he started, but said that his feelings changed to a more wavering skepticism during the research, after encountering a minority of UFO reports he thought were unexplainable. </p><p>Ruppelt left Blue Book in February 1953 for a temporary reassignment. He returned a few months later to find his staff reduced from more than ten, to two subordinates. Frustrated, Ruppelt suggested that an Air Defense Command unit (the 4602nd Air Intelligence Service Squadron) be charged with UFO investigations. </p> <div class="mw-heading mw-heading4"><h4 id="Robertson_Panel">Robertson Panel</h4><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Project_Blue_Book&amp;action=edit&amp;section=4" title="Edit section: Robertson Panel"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/Robertson_Panel" title="Robertson Panel">Robertson Panel</a></div> <p>In July 1952, after a build-up of hundreds of sightings over the previous few months, a series of radar detections coincident with visual sightings were observed near the National Airport in Washington, D.C.

The Robertson Panel first met on January 14, 1953 in order to formulate a response to the overwhelming public interest in UFOs. </p><p>Ruppelt, Hynek, and others presented the best evidence, including movie footage, that had been collected by Blue Book. After spending 12 hours reviewing 6 years of data, the Robertson Panel concluded that most UFO reports had prosaic explanations and that all could be explained with further investigation, which they deemed not worth the effort. </p><p>In their final report, they stressed that low-grade, unverifiable UFO reports were overloading intelligence channels, with the risk of missing a genuine conventional threat to the U.S. Therefore, they recommended the Air Force de-emphasize the subject of UFOs and embark on a debunking campaign to lessen public interest. They suggested debunkery through the mass media, including <a href="/wiki/The_Walt_Disney_Company" title="The Walt Disney Company">Walt Disney Productions</a>, and using psychologists, astronomers, and celebrities to ridicule the phenomenon and put forward prosaic explanations.<sup id="cite_ref-11" class="reference"><a href="#cite_note-11"><span class="cite-bracket">&#91;</span>11<span class="cite-bracket">&#93;</span></a></sup> Furthermore, civilian UFO groups "should be watched because of their potentially great influence on mass thinking ...

The 4602nd AISS was assigned the task of investigating only the most important UFO cases with intelligence or national security implications. These cases were deliberately siphoned away from Blue Book, leaving Blue Book to deal with the more trivial reports. </p><p>General <a href="/wiki/Nathan_F._Twining" title="Nathan F. Twining">Nathan Twining</a>, who started Project Sign in 1947, was now Air Force Chief of Staff. In August 1954, he was to further codify the responsibilities of the 4602nd AISS by issuing an updated Air Force Regulation 200-2. In addition, UFOs (called "UFOBs") were defined as "any airborne object which by performance, aerodynamic characteristics, or unusual features, does not conform to any presently known aircraft or missile type, or which cannot be positively identified as a familiar object." Investigation of UFOs was stated to be for the purposes of national security and to ascertain "technical aspects." AFR 200-2 again stated that Blue Book could discuss UFO cases with the media only if they were regarded as having a conventional explanation. If they were unidentified, the media was to be told only that the situation was being analyzed. Blue Book was also ordered to reduce the number of unidentified to a minimum. </p><p>All this work was done secretly. The public face of Blue Book continued to be the official Air Force investigation of UFOs, but the reality was it had essentially been reduced to doing very few serious investigations and had become almost solely a public relations outfit with a debunking mandate. To cite one example, by the end of 1956, the number of cases listed as unsolved had dipped to barely 0.4 percent, from 20 to 30% only a few years earlier. </p><p>Eventually, Ruppelt requested reassignment; at his departure in August 1953, his staff had been reduced from more than ten (precise numbers of personnel varied) to just two subordinates and himself. His temporary replacement was a <a href="/wiki/Noncommissioned_officer" class="mw-redirect" title="Noncommissioned officer">noncommissioned officer</a>. Most who succeeded him as Blue Book director exhibited either apathy or outright hostility to the subject of UFOs or were hampered by a lack of funding and official support. </p><p>UFO investigators often regard Ruppelt's brief tenure at Blue Book as the high-water mark of public Air Force investigations of UFOs, when UFO investigations were treated seriously and had support at high levels.<sup id="cite_ref-clark_12-1" class="reference"><a href="#cite_note-clark-12"><span class="cite-bracket">&#91;</span>12<span class="cite-bracket">&#93;</span></a></sup> Thereafter, Project Blue Book descended into a new "Dark Ages" from which many UFO investigators argue it never emerged.<sup id="cite_ref-clark_12-2" class="reference"><a href="#cite_note-clark-12"><span class="cite-bracket">&#91;</span>12<span class="cite-bracket">&#93;</span></a></sup> However, Ruppelt later came to embrace the Blue Book perspective that there was nothing extraordinary about UFOs; he even labeled the subject a "Space Age Myth". </p> <div class="mw-heading mw-heading3"><h3 id="Captain_Hardin_era">Captain Hardin era</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Project_Blue_Book&amp;action=edit&amp;section=6" title="Edit section: Captain Hardin era"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>In March 1954, Captain Charles Hardin was appointed the head of Blue Book; however, the 4602nd conducted most UFO investigations, and Hardin did not object.

By this logic, a <i>possible</i> <a href="/wiki/Comet" title="Comet">comet</a> became a <i>probable</i> comet, while a probable comet was flatly declared to have been a misidentified comet. Similarly, if a witness reported an observation of an unusual balloon - <i>like</i> object, Blue Book usually classified it as a balloon, with no research and qualification.

Hynek's plans came to naught. </p><p>During Friend's tenure, ATIC contemplated passing the oversight of Blue Book to another Air Force agency, but neither the Air Research and Development Center nor the Office of Information for the Secretary of the Air Force was interested. </p><p>In 1960, there were U.S. Congressional hearings regarding UFOs.

Ruppelt wanted their experts to assist them in making the Air Force UFO study more scientific. It was the Battelle Institute that devised the standardized reporting form. Starting in late March 1952, the Institute started analyzing existing sighting reports and encoding about 30 report characteristics onto <a href="/wiki/IBM" title="IBM">IBM</a> <a href="/wiki/Punched_cards" class="mw-redirect" title="Punched cards">punched cards</a> for computer analysis. </p><p>Project Blue Book Special Report No. 14 was their massive statistical analysis of Blue Book cases to date, some 3200 by the time the report was completed in 1954, after Ruppelt had left Blue Book. Even today, it represents the largest such study ever undertaken. Battelle employed four scientific analysts, who sought to divide cases into "knowns", "unknowns", and a third category of "insufficient information." They also broke down knowns and unknowns into four categories of quality, from excellent to poor. E.g., cases deemed excellent might typically involve experienced witnesses such as airline pilots or trained military personnel, multiple witnesses, corroborating evidence such as radar contact or photographs, etc. In order for a case to be deemed a "known", only two analysts had to independently agree on a solution. However, for a case to be called an "unknown", all four analysts had to agree. Thus the criterion for an "unknown" was quite stringent. </p><p>In addition, sightings were broken down into six different characteristics—color, number, duration of observation, brightness, shape, and speed and then these characteristics were compared between knowns and unknowns to see if there was a statistically significant difference. </p><p>The main results of the statistical analysis were: </p> <ul><li>About 69% of the cases were judged known or identified (38% were considered conclusively identified while 31% were still "doubtfully" explained); about 9% fell into insufficient information. About 22% were deemed "unknown", down from the earlier 28% value of the Air Force studies.</li> <li>In the known category, 86% of the knowns were aircraft, balloons, or had astronomical explanations. Only 1.5% of all cases were judged to be psychological or "<a href="/wiki/Crackpot_(person)" title="Crackpot (person)">crackpot</a>" cases. A "miscellaneous" category comprised 8% of all cases and included possible hoaxes.</li> <li>The higher the quality of the case, the more likely it was to be classified unknown. 35% of the excellent cases were deemed unknowns, as opposed to only 18% of the poorest cases.</li></ul> <p>(More detailed statistics can be found at <a href="/wiki/Identified_flying_object" class="mw-redirect" title="Identified flying object">Identified flying objects</a>.) </p><p>Despite this, the summary section of the Battelle Institute's final report declared it was "highly improbable that any of the reports of unidentified aerial objects ... represent observations of technological developments outside the range of present-day knowledge." A number of researchers, including <a href="/wiki/Bruce_Maccabee" title="Bruce Maccabee">Bruce Maccabee</a>, who extensively reviewed the data, have noted that the conclusions of the analysts were usually at odds with their own statistical results, displayed in 240 charts, tables, graphs and maps. Some conjecture that the analysts may simply have had trouble accepting their own results or may have written the conclusions to satisfy the new political climate within Blue Book following the Robertson Panel. </p><p>When the Air Force finally made Special Report #14 public in October 1955, it was claimed that the report scientifically proved that UFOs did not exist. Critics of this claim note that the report actually proved that the "unknowns" were distinctly different from the "knowns" at a very high <a href="/wiki/Statistical_significance" title="Statistical significance">statistical significance</a> level. The Air Force also incorrectly claimed that only 3% of the cases studied were unknowns, instead of the actual 22%. They further claimed that the residual 3% would probably disappear if more complete data were available. Critics counter that this ignored the fact that the analysts had already thrown such cases into the category of "insufficient information", whereas both "knowns" and "unknowns" were deemed to have sufficient information to make a determination. Also, the "unknowns" tended to represent the higher quality cases, q.e. reports that already had better information and witnesses. </p><p>The result of the monumental BMI study was echoed by a 1979 French <a href="/wiki/GEIPAN" title="GEIPAN">GEPAN</a> report which stated that about a quarter of over 1,600 closely studied UFO cases defied explanation, stating, in part, "These cases ... pose a real question."<sup id="cite_ref-Randles2202_36-0" class="reference"><a href="#cite_note-Randles2202-36"><span class="cite-bracket">&#91;</span>36<span class="cite-bracket">&#93;</span></a></sup> When GEPAN's successor <a href="/wiki/GEIPAN" title="GEIPAN">SEPRA</a> closed in 2004, 5800 cases had been analyzed, and the percentage of inexplicable unknowns had dropped to about 14%.
