I think we will get "government disclosure" within the next 5-10 years, but it will be full of half truths and misinformation. They'll probably say something like "we have these unknown objects in our skies, but we totally have no more knowledge about them than you do, and we are totally absolutely not hiding any secret technology from you that we reverse engineered from downed crafts. Anyone who suggests so is a crazy lunatic crackpot conspiracy theorist".
My point is to take any "official" government disclosure with a massive grain of salt. Instead we should keep an eye out for any story that comes out that is suppressed or ridiculed in the mainstream media, because usually those are the ones actually worth looking into.
