Ruppelt, Edward J (1956). The Report on Unidentified Flying Objects (1st ed.). Doubleday & Company. p. 62. Archived from the original on 2010-01-12. Shallet's article - He pointed out how the "furor" about UFO reports got so great that the Air Force was "forced" to investigate the reports reluctantly. He didn't mention that two months after the first UFO report ATIC had asked for Project Sign since they believed that UFO's did exist. Nor did it mention the once Top Secret Estimate of the Situation that also concluded that UFO's were real. In no way did the article reflect the excitement and anxiety of the age of Project Sign when secret conferences preceded and followed every trip to investigate a UFO report. This was the Air Force being "forced" into reluctantly investigating the UFO reports.
