This whistleblower (whistleblower is inaccurate in this case because he got the approval of The Defense Office of Prepublication and Security Review) has already made his presentation to the classified committees of Congress.
As an aside, I don't think anyone of substance has drawn a conclusion one way or another re: these allegations. The DOD has denied their accuracy and NASA has denied any knowledge of such programs.
Right now all we have are some potentially earth-shattering claims on one hand and some vehement denials on the other.
As some on this thread have said, the jury will be out until something substantial (if not absolute proof) is delivered to the public.
Some have said that the "drip, drip, drip" of disclosure just turned into a spurt.
The answer to the problem of the Unidentified Flying Object is to identify it. Then we don't have to call it an "object." If there is any tangible and undeniable proof, that should be a piece of cake. Or a squirrel. Look!
I wonder, since the "competing claims" game of the last "pandemic" event has gone by, and the "competing claims" of the Ukie-Ruskie are (present tense) going by, whether this is all just "stoking" the media fires. Rabbit holes, once one chases down them, can occupy a lot of one's time and energy.
