In response to the Condon Committee's conclusions, Secretary of the Air Force Robert C. Seamans, Jr. announced that Blue Book would soon be closed, because further funding "cannot be justified either on the grounds of national security or in the interest of science. As Michael Hall writes, "Ruppelt not only took the job seriously but expected his staff to do so as well. By the time he was transferred from Blue Book in 1963, Friend thought that Blue Book was effectively useless and ought to be dissolved, even if it caused an outcry amongst the public. One of these men was Gen. Charles P. Cabell. The apparent irresponsibility and the possible use of such groups for subversive purposes should be kept in mind.
If they were unidentified, the media was to be told only that the situation was being analyzed.

Letter to Major Hector Quintanilla, Jr. 2 Dec. 1965. Each U.S. Air Force Base had a Blue Book officer to collect UFO reports and forward them to Ruppelt. About 22% were deemed "unknown", down from the earlier 28% value of the Air Force studies. Vandenberg subsequently dismantled Project Sign. As a result of the Condon Report (1968), which concluded there was nothing anomalous about UFOs, and a review of the report by the National Academy of Sciences, Project Blue Book was terminated in December 1969. Hynek was to later declare that Sleeper's letter was "the first time in my 20 year association with the air force as scientific consultant that I had been officially asked for criticism and advice [regarding] ... the UFO problem.". Inadequate use had been made of the Project scientific consultant [Hynek himself]. Also the "unknowns" tended to represent the higher quality cases, q.e. In his dissenting conclusion, Hynek described Blue Book's conclusions as absurd: in their reports, several of the police had unknowingly described the moon, Venus and the UFO, though they unknowingly described Venus as a bright "star" very near the moon. Blum writes that some of these official documents depart drastically from the normally dry and bureaucratic wording of government paperwork, making obvious the sense of "terror" that these UFO incidents inspired in many U.S.A.F.
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.  Raymond Fowler (of NICAP) added his own interviews with the locals, who saw Air Force officers confiscating newspapers with the story of UFOs and telling them not to report what they had seen. However, researcher Brad Sparks, citing research from the May, 1970 issue of NICAP's UFO Investigator, reports that the last day of Blue Book activity was actually January 30, 1970.  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 chain of command. 国防長官。ハーディング大将らが進めるプロジェクトを中止し、神経化学兵器の開発を進める。意向に沿わないハーディング大将を警戒している（第8話）。, ヘンリー・フラー（マット・オリアリー） In fact, there was actually little or no investigation of UFO reports; a revised AFR 200-2 issued during Gregory's tenure emphasized that unexplained UFO reports must be reduced to a minimum. 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 little serious investigation, and had become almost solely a public relations outfit with a debunking mandate.
