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.

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.
