You would be shot and killed before you reached the edge. Antarctica is patrolled by the US military 24/7 to keep the "environment safe". Also GPS does not work at the north pole and near the edges of flat Earth.
The "US miltary" ? I thought it was NASA ?
Could you sail far enough off the coast of the edge to be safe, but close enough to keep the edge in sight, even with a telescope ? Do they have armed patrol boats or long range coastal gun emplacements around the edge to prevent anyone from even getting within sight of the edge ? Could it be there is a Top Secret Fleet....maybe NASA, the US or even the UN patrolling the edge ?
After all, the ice wall is said to be 150 feet high, but how do they know this ?
The only evidence I have seen is in Rowbotham's writing. Where did he get his information ?
Did he see it himself ? As far as I have read, he never had been out of England ?
The only account is of an ice shelf on Antarctica. And flat earthers claim the map of Antarctica, (as a Continent) showing these ice shelfs (several of them, but not a continuous ice wall) is a fake ?
