The proponents of UFOs offer up impressive quantities of principally eyewitness data, which although largely subjective and circumstantial in nature, is nevertheless quite intriguing.... Many of the high-quality sighting reports involve certain objective aspects, which, to an open-minded bystander, are quite impressive.
As a full-time, and serious-minded, UFO investigator, I strongly side with the proponents. It seems indisputable that the phenomenon is real, and that it falls outside the scope of "normal" human experience.
Strong evidence suggests that we are dealing with a phenomenon that is being caused by palpable, solid objects whose characteristics are not of human design, and whose behavior is suggestive of intelligent control.
