Some probs I have with that article Selassie...
First, we've been hearing pilots discuss UFOs that have aerodynamic capabilities that outstrip our own for decades. This is not a new thing. I was in aviation for 30 years. Pilots see all kinds of shit but the stigma was actually that nothing would be done or their standing would be affected if they reported them so they were not worth the risk.
Secondly the technology is not there for any terrestrial nation to put out these drones. If these things that swarmed US Navy Destroyers were terrestrial drones they would need to outperform known technology in velocity and sustainability (massively improved batteries or beamed power from some source in orbit). Their movement is still ahead of what humanity can do, but we're getting closer to being able to figure out what they are.
Lastly if China's technology was that good they'd beat our asses right now. They'd be forcing countries to sign shit to put them under their umbrella and expanding because they can. Those fuckers have been doing BS for a while now, they started years ago with infringements into the seas around them like those in the Filipines. But most of their technology is stolen from us. They do have some surprising tech areas, sure. But overall they're still an upstart and like Russia in spite of some areas of possible superiority in the spectrum of tech they're trailing.
The drones that swarmed the destroyers off the coast of California would require beamed power from satellites or massively superior battery technology to sustain for hours. Not to mention massive tech jump in propulsion. Neither of those things are likely. And they would require a launch solution like a sub or base nearby which are unlikely given Destroyers operating in simulated combat scenario in those littoral waters. Here's the story of that particular incident, which the article that you linked believes to be terrrestrial drones. But I think that is very unlikely and I think we're going to find out soon that UFOs are real. Because it affects more than just any one country.
The disturbing series of events during the summer of 2019 resulted in an investigation that made its way to the highest echelons of the Navy.
