Meeting of OSI Advisory Group on UFO

This memorandum, dated January 21, 1953, summarizes the findings of an ad hoc panel of scientific consultants convened by the CIA's Office of Scientific Intelligence (OSI) between January 14 and 17, 1953, to review the 'Unidentified Flying Objects' problem. The panel, which included experts such as Dr. Robertson, Dr. Luiz-Alvarez, Dr. S. Goudsmit, Dr. Thornton Page, and Dr. J.A. Hynek, reviewed evidence provided by representatives from ATIC, the Navy photo interpretation lab, and the Air Force Directorate of Intelligence. The panel reached four primary conclusions. First, they determined that there was no evidence to suggest that UFOs posed a physical threat to the security of the United States. Second, they found no evidence that UFOs utilized any unknown fundamental scientific principles. Third, the panel stated that the subject of UFOs was not of direct intelligence interest, though it remained of indirect interest regarding the broader mysteries of the universe. Finally, the panel identified that UFOs were of operational interest for three specific reasons: the potential for interference with air defense systems due to intentional enemy jamming or the inability of personnel to distinguish between radar anomalies and actual aircraft; the potential for interference with air defense communication lines; and the possibility that an enemy could use the subject for psychological warfare to disrupt the defense efforts of the general public. The document concludes by noting that these findings did not fully address the specific needs outlined in Appendix A, and that a further written statement from the panel to the AD/SI was anticipated.
