(MS, Engineering), Gerald M. Rothberg (PhD, Physics), Herbert J. Strentz (MA, Journalism), and James E. Wadsworth (BA, Behavioral Science).

The hard core of the report is Section CR IV, which presents 59 cases. In this work, the Director took no part; one Principal Investigator worked on two cases, another Principal Investigator on one case; the Co-Principal Investigator took no part; the Project Coordinator worked on eight cases; one Research Associate (Dr. Levine) worked on eight cases; Dr. Rothberg on one case; and Mr. Wadsworth on 17 cases. Important contributions to case studies were made by Roy Craig (PhD, Physical Chemistry) and William K. Hartmann (PhD, Astronomy), who are listed simply as “staff members.” Craig and Hartmann each worked on 14 cases.

The next most important section is Section CR III, which presents six summaries of the work of the Colorado Project, together with a review of opinion polls by Aldora Lee (PhD, Social Psychology). None was written by the Director, one by a Principal Investigator (Roach), none by the Research Associates. Three chapters were written by Craig, one by Hartmann, and one by Gordon Thayer (BS, Physics).

Section CR V, dealing with historical aspects of UFO phenomena, comprises three chapters, and Section CR VI, dealing with “The Scientific Context,” comprises 10 chapters. Of these 13 chapters, one was written by the Director. The remaining 12 chapters were written by staff members not previously listed in this discussion.

Concerning Sections CR III to V. it is seen that a substantial contribution was made by one Principal Investigator (Roach) and by the Project Coordinator. The remainder of the staff made no contribution to the Report or only specialized contributions. Section CR I, “Conclusions and Recommendations,” and Section CR II, “Summary of the Study,” were written by the Director. This breakdown is summarized in Table 1.

Another important part of any scientific study is the definition of the scope of the study and definitions of the principal terms involved. Condon states (Condon & Gillmor, 1968, p. 1) that “The emphasis of the study has been on attempting to learn from UFO reports anything that could be considered as adding to scientific knowledge.” His conclusion (Condon & Gillmor, 1968, p. 1) was that “nothing has come from the study of UFOs in the last twenty years that has added to scientific knowledge. . . . Further extensive study of UFOs probably cannot be justified in the expectation that science will be advanced thereby.”

The key definition is given by Condon as follows:

An unidentified flying object (UFO, pronounced OO-FO³) is here defined as the stimulus for a report made by one or more individuals of something seen in the sky (or an object thought to be capable of flight but seen when landed on the earth) which the observer could not identify as having an ordinary natural original, which seemed to him sufficiently puzzling that he undertook to make a report of it to the police, to
