I understand your viewpoint but I suppose there are many for whom the reality is not yet proven - I know there are skeptics out there who dance around the line of acceptance, although yes, for those of us well into Ufology, there is really no question of craft being flown/operated that do not seem to have any human source.
I think that there probably is still work to do in tracking UFOs - perhaps that work will not make someone accept/not accept ufo reality but it could still provide some worthwhile data. I personally would be very interested in answers to the following:
1. maximum speed in atmosphere/above atmosphere (space).
2. Acceleration/deceleration values.
3. Average duration of flights.
4. Geographical distribution.
5. Any regular/common flightpaths.
6. Correlation with human activities/sites on ground.
7. Possible differences in propulsion methods if feasible to differentiate.
8. Craft/object sizes.
9. Differing modes of flight - e.g forgetting whether Lazar story is real or not but he mentioned modes of a saucer moving like a helicopter in as much as its aspect relative to the ground, and a further mode in which it would 'turn on it's side' (Omicron I think it was called).
These are just off the top of my head and while they might not convince anyone who is not already convinced, I think our ability to classify and define craft and flight characteristics can be improved immeasurably because frankly, we don't have any accepted reference material/data on much of this, even though regional groups like GEIPAN may have gone some way along these lines.
I think even though there must be literally thousands upon thousands of scientists worldwide with an interest in the topic of UFOs, it still is not an accepted area of study in the main scientific literature and I doubt many universities teach anything about UFOs, certainly not in engineering or aerospace disciplines. I personally believe there is ample evidence for UFO reality and it may be other factors that have led to the current situation but regardless, Ufology is not an 'accepted' pursuit of 'real science' in most of the world. It may just be the case that the kind of effort stated above, is what is needed to bring the field properly out into the open and leave the curtain of laughter and giggles firmly in the 6-O'clock News cutting room floor for evermore! Phew!
