Who's to say, the Anti-Grav scientists didn't do the same thing.
The first true 'flying saucer' sightings started in 1947. Who knows what development have been made since then.
And, no, I am not dismissing the sightings, texts or descriptions from the ages. Only saying the technology developments necessary for this type of flight are recent developments.
Did you know that they coincidentally still do gravity research at that same location?
Did you know that they likely got their head start from even earlier work started by someone in the US?
YouTube has several videos of the actual researchers in their labs from 40/50s doing work related to this. Im guessing that too many believe that watching real footage of real science is “conspiracy theory” stuff.
There is all kinds of official documentation of the reality of what we have done and are presently doing. Its not space aliens and it certainly isn’t interdimensional demons. Its us. The Russians had at least the initial documentation on this research for a long time. The Chinese likely have stolen an updated version by now. There is no one to hide its reality from anymore exceptbut the people.
There is a change coming that will effect all of us more profoundly than the invention of the combustion engine and a lot of very wealthy people are going to lose their position in this world. Yes, I know, “We’ve all heard this before,” but this time its quite different. Those that cant see it might want to start by trying to come at it from a different direction and figure out why Trump chose now to take on the fed/float hard currency.
