In November 1970, the UFO subcommittee of the American Institute of Aeronautics and Astronautics (“AIAA”) published a statement entitled “UFO, An Appraisal of the Problem” in its journal, Astronautics and Aeronautics, criticizing the conclusions of the Condon Report and encouraged further study of the UFO problem. It concluded that it found it “difficult to ignore the small residue of well-documented but unexplained cases which form the hard core of the UFO controversy”.
