Its BS.
The real story here (so far) is not the UFO's. The story is what is the objective of those pushing it (the story).
This story is being generated by the Navy, some Navy pilots and radar operators, the DOD (Elizondo, Mellon), and Lockheed. Those parties, seemingly in concert, have produced and/or corroborated the story line and then fed that story line to Tom DeLonge and the History Channel, who in turn produced a documentary on it entitled "Unidentified."
So the question goes to motive.
First, let's do away with a scenario in which in the Navy and DOD are being used (wittingly or unwittingly) to provide an air of respectability/credibility to a story that has been concocted by the non-governmental parties (retired pilots and former guvvie agents) for the sole purpose of making a profit.
Making money from such a story is always a tempting motive. The question here is "would the Navy and DOD permit themselves to be so used without having an overriding ulterior motive?" Doubtful.
The next possibly motive "question" would be, if the Navy and DOD have either signed off on this story moving forward or are in some way a part of it, what would be their possibly motive?
Just on the surface, their possible motives might be:
(1) Get this story out there as part of their new policy of encouraging pilots and others to report UFO's. In other words, they have no interest in where this leads (they don't know or care). They are just showing their pilots that it is OK to report such stories...there will be no negative repercussions from them. And if the pilots make some money off their stories/mysteries, no problemo.
(2)The Navy and DOD are letting this story get out there as a way of telling our enemies (obliquely of course) that we are developing weapons way beyond those envisioned by Russia or China. So take that Russian and Chinese hypersonic missile proponents.
(3)The Navy and DOD are actually telling the U.S. public that they have detected enemy aircraft capable of penetrating our airspace and eluding our aircraft and defenses. ER, NO. SCRATCH THAT.
(4) The Navy and DOD are disclosing--finally--that they have made contact with aliens and their UFO's. Doubtful, but who knows.
