We can - and do - speculate endlessly about what cases might or might not be real and whether the military has or doesn't have anything stashed away. But we do know for certain that in the past the military absolutely has wanted to push the narrative that they have EBEs, craft, all sorts of things being hidden away. They have gone to great lengths to do so including co-opting ufologists and driving poor Paul Bennewitz nuts. Yet at the same time also go to great lengths to deny it all. They didn't just stop doing that all of a sudden, the public interest in the subject is real and as long as it is this sort of manipulation works for their purposes; purposes unrelated to whether ET is here or not. Of the percentage that are true unknowns they really don't seem to be bothering us that much. I really don't know what to make of Grusch right now but we haven't heard from any of the other whistleblowers or precisely why the two IGs felt his case was 'credible and urgent'. We naturally want to assume it's because of the reality of ET and Disclosure because of the shocking nature of what he's said but the actual practical truth may not be that at all, it could be some aspect of national security or God knows what else. What he is saying isn't much different than the narrative Doty was peddling.
It increasingly sounds like the Reid/Bigelow partnership, AAWSAP, AATIP, Elizondo, Mellon and by extension Skinwalker were a well connected and well funded personal interest that the mainstream DoD did not and does not look favorably upon. The AARO report makes it sound like something that never got too far off the ground and in that light explains why Elizondo & Co have been promoting their involvement in a government program that the government doesn't want to acknowledge and again, we want to assume it's Disclosure but I don't think that's the case. It does serve the narrative though.
And as a gratuitous add on, did I read that part of the report right? Sounded like Art's Parts got that Army CREDA because the Army developed the material and has possession of it again. A few years ago there were endless, lengthy debates about all that and now .... we seem to have moved on.
