It's also interesting how these alleged observations seem to exclusively happen within restricted US airspace over oceans - but not over US land.

My bet has to be on it being an elaborate disinformation campaign, to throw off our nationstate adversaries and keep the public in fear and/or distracted. It requires one to be super cynical, but our government has done worse to US citizens in terms of disinformation [0] (but not since the 70s that i know of).
That explanation accounts for why these sightings only appear to happen in the US, and is (to me) far more believable than an encounter with otherworldly technology.
At least with respect to the 2004 encounter, I think the least likely explanation is that the object belonged to another superpower - b/c it feels like something totally out of reach in multiple domains for 2004 tech.
