The latest is "Ignoring History".

There is much that "ufologists" choose to ignore... One area of great importance, which virtually all "nuts and bolts" ufologists ignore, is history. They pay lip service to the idea that the "UFO phenomenon" has a past, but just barely. They are aware that people have been seeing strange things in the sky for millenia, but they would rather gloss over that subject, because these phenomena weren't interpreted as extraterrestrials, and they weren't called "UFOs." They were interpreted in the context of the myths and folklore of the era in which they appeared; a comet, for example, was interpreted as a "finger of doom" pointing at the earth, or a "celestial broom," come to sweep the earth clean of good and evil alike...
The phenomena that gave rise to various beliefs way back when stand apart from the interpretations placed upon them; perhaps a prosaic explanation of a certain account suggests itself to the modern mind, perhaps not. Precisely the same is true of "modern" UFO reports. A phenomenon giving rise to the modern ufo report may be utterly mundane in nature, or it may defy all attempts at explanation. The interpretations of these unexplained events, however, are born out of the propensity of human beings to interpret the unknown in terms of myth, of folklore, of the preternatural or supernatural. We are not so terribly different from our forebears.
