A bumpy start

[18. February 2019] 

We are still in Punta Arenas at the pier in Cabo Negro to take on fuel. Later, we need to take on kerosene for the helicopters and finish last cargo operations. If everything works according to plan, we should hopefully be on our way to Antarctica on Monday morning. However, all in good order …
