Condon Report — Scientific Study of Unidentified Flying Objects

The University of Colorado study, directed by physicist Edward U. Condon and published in 1968–69, was the Air Force’s contracted exit from the saucer business. Condon’s summary said there was no evidence of a threat or of extraordinary science, and that universities should not spend more on the subject. The National Academy of Sciences endorsed that summary.

Inside the same book, case investigators left a number of reports unidentified. Critics, including some who worked on the study, said the conclusion was written before the cases were. The document is both: a public scientific report, and the paper that closed Blue Book’s era.
