Unknown craft caught exiting sub-glacial launch facility in Antarctica

A new discovery in Antarctica. According to Florida Marquis, Google Earth shows a craft that takes off from a secret sub-glacial launch facility in Antarctica.


It is remarkable that the 2019 imagery layer shows the area completely covered with snow. The location that can be seen in the imagery layer of 2010 has been vanished!
