Over the past eighteen years I have acted as a scientific consultant to the U.S. Air Force on the subject of unidentified flying objects - UFO's. As a consequence of my work on the voluminous air force files and, to a greater extent, of personal investigation of many puzzling cases and interviews with witnesses of good repute, I have long been aware that the subject of UFO's could not be dismissed as mere nonsense.

Science is not always what scientists do.

Each wave of sightings adds to the accumulation of reports which defy analysis by present methods... An investigative process in depth is necessary here if, after twenty years of confusion, we want some answers.

When the long awaited solution to the UFO problem comes, I believe that it will prove to be not merely the next small step in the march of science but a mighty and totally unexpected quantum jump.

I have begun to feel that there is a tendency in 20th Century science to forget that there will be a 21st Century science, and indeed a 30th Century science, from which vantage points our knowledge of the universe may appear quite different than it does to us. We suffer, perhaps, from temporal provincialism, a form of arrogance that has always irritated posterity.

As a scientist I must be mindful of the past; all too often it has happened that matters of great value to science were overlooked because the new phenomenon did not fit the accepted scientific outlook of the time.
