Premised that I never been an UFO's fan, I see that there is a change of communication paradigm:
- in past authorities tried to deny any off nominal aerial phenomena especially when connected with possible little green men
- today such phenomena are acknowledged even if (correctly) no further explanation is provided, leaving the door open to all possible speculations.
The point is more than 80 years that accountable eyewitnesses (pilots, military people, policemen etc.) spot off nominal aerial phenomena, all those people has nothing to gave and everything to loose reporting an UFO encounter. Indeed since the "Foo Fighters" during WWII (and maybe even earlier), all the same categories of objects are spotted.
Spheres, cylinders, triangles and other more or less geometrical shapes are seen above the sky or the sea, most of them have alsways the same aerodynamical uncoventional behavior (speed, maneuvers and accelerations that not are in accord with current TRL) and this is clearly showed off also in the Navy's recent videos.
What or who they are?
Honestly I don't know and I don't want to fulfill the easy equation: UFO/UAP=Aliens, but they are for real we now know it.
At least are real what military entities see and record.
Since such strange and off nominal aerodynamic behaviors are recorded by since I would exclude (for historical reasons) USSR/Russia and China.
This not exclude that some of such phenomena couldn't belong to China for instance but not enterity of them.
