McDonald, a senior atmospheric physicist (University of Arizona), “considered the best reports to be evidence of extraterrestrial visitation” and stressed “the need for a serious scientific study.”

On the Condon Report’s inadequate case selection:

“The report analyses only about ninety cases, a tiny fraction of the significant and scientifically puzzling UFO reports now on record.”

On its weak analysis:

“Specious argumentation, and argumentation of scientifically very weak nature, abound in the Report’s case-analyses.”

On misrepresentation:

Some cases exhibited “disturbingly incomplete presentation of relevant evidence; in a few instances, such defects seem little short of misrepresentation.”

On the conclusions-vs-evidence gap (the core indictment):

“Despite all of the above, those who prepared the Report ended up with about a dozen … of their cases in their ‘Unexplained’ category. Some are extremely significant UFO cases … yet these Unexplained UFOs appear to have been casually ignored by Condon.”

His characteristic framing (well-attested across his lectures): the extraterrestrial hypothesis was, in his assessment, the “least unlikely” explanation for the best-documented cases — offered as the strongest scientific hypothesis given the data, paired with insistent calls for rigorous study, not as a maximalist certainty.
