This is the final report of the Scientific Study of Unidentified Flying Objects, conducted by the University of Colorado under Air Force contract F44620-67-C-0035, with Edward U. Condon as scientific director and Daniel S. Gillmor as editor. It was submitted to the National Academy of Sciences on 15 November 1968 for review. The report includes field studies, photographic and radar analyses, case studies, historical chapters and appendices such as the Robertson Panel report and the Twining letter.
Chapter 3 Direct Physical Evidence Roy Craig Several types of physical effec.ts have been presented as evidence that an object of unusual nature had been present at a giv~n location. Such effects consist of: (1) markings on ground, vegetation, or objects with which an UFO, as something from an UFO, reportedly made direct or indirect physl~al contact; (1) material residue allegedly deposited from or by an UFO; and (3) articles or portions of articles manufactured by intelligent beings, but reportedly not produced by known cultures. A fuurth known conceivable type of physical evidence, consisting of a non-earthly or captured "flying', saucer," would be most impressive as evidence. The exis~ence of this type of evidence has been suggested by some rep0rters, SUCl as Moseley (1967), who reported the claim that a captured flying saucer was held at a military base in Ohio, and A11en (1958), who pre- sented a photograph of n tiny humanoid creature and four adult Earth residents, claiming that the creature was a crewms'l of a S1ucer which crashed near Mexico City in 1950. During the course of this study, how- ever, no indication was found that this fourth type of evidence has ever existed. 1, Markings Allegedly Made By UFOs Claims of evidence of the first type are common. UFO reports contain numerous descriptions, often vn th support lllg photographs of saucer "nests" .,- areas where soil, grass, cattails, or other vegeta- tion had Leen flattened, burned, broken off, or blown away, alleg~dly by an UFO that lanJed or hoverlJd there.
