Editing Aerial Phenomenon Research Group (APRO) (section)

== Focus on the scientific method ==
APRO stressed scientific field investigations, and had a large staff of consulting Ph.D. scientists. A notable example was James McDonald of the University of Arizona, a well-known atmospheric physicist, and perhaps the leading scientific UFO researcher of his time. Another was James Harder of the University of California, Berkeley, a civil and hydraulic engineering professor, who acted as director of research from 1969 to 1982. McDonald and Harder were among six scientists who testified about UFOs before the U.S. House of Representatives Committee on Science and Astronautics on July 29, 1968, when they sponsored a ''one-day'' symposium on the subject.

Astronomer [[J. Allen Hynek]] cited APRO and [[NICAP]] as the two best civilian UFO groups of their time, consisting largely of sober, serious minded people capable of valuable contributions to the subject.
