BTW, I don’t think I’ve ever known, where does your certainty of conviction come from re UFO stuff generally?
And how would you summarize it?
The problem with studying transient phenomena — including UFO encounters — is that they don’t generally show up at convenient times, and are not reproducible in the precise laboratory sense. They have to be studied in total, in order to find common characteristics. Anything the gubmint may have locked away about sightings, crashes, etc are otherwise unremarkable, and can’t tell us anything about planetary origin etc.
That DVD set is somewhat interesting, not too lurid and tabloidy, decent depth, and isn’t merely regurg’ing the well-known stuff (although some of that has been covered as well).
