Maybe an explanation

I’m a skeptic on the topic. Too much is blurry photos and “I know a guy” stories.

But, if true, what could justify the coverup? I wonder if the technology involved with these UAP are not so advanced that it renders all existing armaments impotent? What then of the defense industries in all industrialized countries? The “military industrial complex”? Would not those people have vested interests in concealing that there is something out there, something we and maybe other counties have harnessed, that renders our existing armaments obsolete?
