Australian Department of Defense Paper on the Scientific and Intelligence Aspects of the UFO Problem

1947-196919 pp.Confidence: MEDIUMhigh

This is a nineteen-page analytic paper held in the National Archives of Australia (NAA: A13693, 3092/2/000) examining the scientific and intelligence aspects of the UFO problem, written from an Australian Department of Defense viewpoint and recommending that another government department assume responsibility for UFO investigation. It reconstructs the U.S. handling of UFOs from the 1947 Arnold sighting through Project SIGN, GRUDGE, and BLUE BOOK, the Robertson panel, and the Condon report, and includes a detailed event chronology (Appendix A).

Key excerpts

“The body of the report prepared between March 1952 and early 1953, although biased in favour of a natural explanation for UFO's, nevertheless showed mathematically that the evidence favoured an explanation that was scientifically unknown. This section of the 116 page report was not released to the public other than as a copy to be consulted, assuming the reader knew of its existence. (p. 4)”
