Condon Report

Comprehensive scientific study of unidentified flying objects conducted by the University of Colorado from 1966 to 1968 under physicist Edward U. Condon, commissioned by the U.S. Air Force to provide independent academic assessment of UFO phenomena and determine whether continued official investigation was scientifically warranted.

The study emerged from growing criticism of Air Force UFO investigations, particularly Project Blue Book, which faced accusations of inadequate scientific methodology and predetermined debunking conclusions. The Air Force contracted with the University of Colorado to conduct an objective review of UFO reports using rigorous scientific standards and multidisciplinary analysis.

Condon’s team investigated 91 UFO cases using expertise from astronomy, physics, meteorology, psychology, and other relevant fields, employing both field investigation and laboratory analysis of physical evidence including photographs, radar data, and material samples. The investigation included both recent reports and historical cases from military and civilian sources.

The final 1,485-page report concluded that further systematic study of UFO reports was not likely to advance scientific understanding, finding no evidence that UFO phenomena represented extraordinary or extraterrestrial technology. However, the study acknowledged that approximately 30% of investigated cases remained unexplained by conventional phenomena.

Critics, including astronomer J. Allen Hynek, argued that Condon’s executive summary misrepresented the study’s actual findings and that many unexplained cases deserved continued scientific attention. The report nevertheless provided the Air Force with academic justification for terminating Project Blue Book in 1969, effectively ending official U.S. government UFO investigation for decades.
