Do we need Harem tag then? For Ayame, of course.
He always was? Frank Drake, I mean.
I wouldn't trust footage released by the current US government as source material...
Well, fundamentally, Unidentified Flying Object, or now, Unidentified Anomalous Phenomena, only means 'Flying shit we have no idea what it was' for the military. And the military just didn't have the expertise or time to really look into it deeply. They're mostly concerned with if it's a threat or not, and if nothings comes of it, they just put the file away.
Most are already explained now that it is released if I understand correctly. A lot has already been before released even, if I'm not wrong. (Most material was released before, but with redacted info that could hint at where the military been to or info on the overlay that might hint to the capability of the equipment detected the footage)
