WHAT HAPPENED WHEN THEY DRILLED INTO AN ICE WALL NEAR THE FIRMAMENT IN THE 60s

Shared from FLAT EARTH BROTHERS channel.
There are a lot of speculations as to what all they are doing in Antarctica beyond simply hiding access to the best proof of creation, so I wanted to share this short comment to shed some light onto one possibility. The Father knew what the foolish powers of darkness would be up to when He desinged the great expanse, so I know there would be barriers and preventative measures in place to stop them as seen with the tower of Babel and Operation Fishbowl. I wasn't shocked to find out they may have tried around the same time operation fishbowl was going on to drill into walls surrounding this expanse or the expanse itself. I do not know the person who made the comment, so I can't say that they were for sure stationed in Antarctica, but would love to track them down if possible. If anyone is able to find them, please let me know.
