I'm not sure that they are going to appreciate my comparison of the 21st century UAP kerfuffle to the surge in garden fairy sightings in the early 20th century....
I totally agree with you, but there are significant differences, if we compare what are arguably the best examples of each:
(1) The assorted DoW/ AARO releases of footage from sensors of/ similar to Raytheon Multi-Spectrum Targeting-type optical systems,
(2) the Cottingley fairies (Wikipedia
https://en.wikipedia.org/wiki/Cottingley_Fairies#)
The footage we see from (1) was captured by contemporary digital optics suites manufactured by major defense contractors, operated by professional military personnel.
The photos of (2) were taken by a 16-year old girl, assisted by her 9 year-old cousin, using a Butcher's Midg No.1 domestic camera, introduced c. 1902 (Camera-wiki.org
https://camera-wiki.org/wiki/Midg; The Living Image website
https://www.licm.org.uk/livingImage/Ensign_Midg.html).
With (1), subject distance from the camera (and sometimes camera location) are not known. Details of platform and camera gimbal movements have not been supplied, but they
may play an important role in
apparent subject speed, acceleration and direction changes, as has been observed before (e.g. GO FAST).
The military personnel/ defense officials submitting these items of footage are necessarily anonymous, to avoid any stigma.
With (2), the exact locations were known, camera-to-subject distances could probably be calculated to within approx. 1m/ 1 yard or so. There were no dynamic factors that might have made interpreting the imagery difficult (the subjects appear to be stationary, as was the camera).
Obviously the identities of the two girls who took the photos was clear from the outset, and they knew this would be the case.
(Maybe there was less stigma in 1917, or the girls were more resilient than some (e.g.) Reaper UAS/ intelligence staff, we can only guess)
Footage from (1) often shows examples of moving areas of contrast, maybe a few pixels in extent, with few if any definable features. Where there is a little more visual information, e.g. fluctuating shapes or brightness, in some instances it might be consistent with birds. In some instances the footage might be from areas where it is plausible that other actors might be using small drones.
The photos from (2) clearly depict what appear to be diminutive, winged but otherwise clearly humanoid- but not human- creatures with crafted clothing, indicating non-human intelligence. Examination of the photographic plates showed no sign of tampering. There are accounts of such creatures from many locations over at least several centuries; there is debate as to their motives. There have been claims of abduction; other believers think they are benign.
Of course, the Cottingley fairies were fakes. But they were not demonstrated to be fakes for over 50 years.
During that time, for believers they might have been seen as self-evidently better evidence of NHI than the AARO files would have been, had they (or some approximate equivalent) existed back then.
ETI is probably more likely than fairies, which don't exist (*
pfft*, there goes another one...)
But the current evidence for ETI visiting Earth is perhaps no better than the evidence for fairies in the early 20th century.
Extraordinarily, there were educated, influential people who believed the Cottingley fairy photographs were real.
I guess we should be grateful the current US administration isn't devoting time to the study of fairies, but if it did, finding an academic to lead the effort might be easier than we might have anticipated.
