Anyone who looks at the practices of earthlings with an impartial eye, would agree. We are killing each other, and being very smug about it.

Anarctica used to be a totally different environment long ago. Who's to say there wasn't an intelligent civilization already down there by then? And has been ever since? 👀 Just fun to think about.

I love anything Antarctica can't wait to see the full episode

Imagine risking your life to explore then people not believing what you saw.. these were professional people, it was their job. Anyone who doesn’t believe it is a conspiracist. Strange how we suddenly stopped with the atomic bombs too..

Antártica was part of the supercontinent called Pangea when giants roamed the Earth. After the Great Flood Pangea broke apart into the continents we have now. So it’s fair to say that whatever civilization or structures were there are still there conserved by all that ice.

I find it strange that a seasoned pillot would fly into a random cave. How would he be sure that he could maneuver inside without crashing or the ability to turn around in order to exit

[dustencross]

Why would any pilot fly a plane into a hole in the ground?

[lucasroe]

Admiral Byrd as qualified, experienced as he was and chosen as leader of this large military expedition, MAY have had a screw loose???

[Alina-wsob]

Nothing is classified. Everything is right there in the Bible. 😊

Do you think when aliens fly past our planet.. they lock the doors on their craft ?

[garysims]

My question is why was rhe admiral of the voyage in a plane flying over flat ice where he happens to come across the hole shouldent he have been a n the ship being the highest officer

[Bruce-xxdq]

Admiral Byrd why is he the only one that knows about this UFOs where's where's all the other people that know all the other witnesses what happened to all these people can somebody tell me this all the other soldiers

[scottlemurianboxer]

Sounds like he found "Shamballah"? Amazing story, doubt it true tho. 😕

[vinc]

so he flew into a cave not knowing if he can crash into a wall not knowing how big/deep it can be, landed? and took off again?? 😂 i want to believe but …

[brucemoriarty]

Byrd was ok, but he flew over the coo Koo's nest.

[susannablessings]

This described his NORTH Pole Trip NOT his Antarctica trip

[TheBmco]

This is not just a story. This is real stuff I know for a fact when I was in the US Navy intelligence officer we were told to stay out of that area only certain places we could go in Antarctica.

[ES-blwy]

Admiral Byrd not Admiral Burn. Can't even get his name right. Description box 👈📖🧐

[franklyntalbert]

Ok he was met with fallen angels under the earth people let’s cut the crap
