Posted in 2019 by Jeff Rense, this short video genuinely shows a couple of flying discs that were built by Germany in the 1940s.
They were known as "foo fighters" by allied pilots who were stunned by their speed and maneuverability.
Many German military and citizens were transported to secret bases in Antarctica as the war in Europe ended - and they continued developing these craft, with assistance from aliens who had given Hitler the technology in the first place.
In 1947 America sent an expedition, including 4000 Marines, to Antarctica, ostensibly as a scientific undertaking, under the command of Admiral Byrd - the first man to have flown to the North Pole.
I have personally seen footage of the fleet being attacked by disc-shaped craft, and basically sent running - including, according to some reports, with the loss of at least one of their ships.
That footage has of course disappeared down the Big Tech memory hole, and it was years ago, before I had the software to download such things.
Recently, Dr Michael Salla has reported that those Antarctic bases have been, or are being, completely taken out as part of the war behind the scenes that is intended to rid this planet of all these evil species.
As for disc shaped craft, both the USA and China, now have such vehicles. This one, below, is from China.
