MarkOz, yeah that would be right re the weather. I was using REX Essential. Weather was crap, low cloud etc on the McMurdo side then came and went to FL's till about 3/4 of the way across, then it cleared to clear with light winds at the Wilkes ice runway location. I used the MAP feature to check WX stations enroute of which there are heaps marked with little blue circles incase I had to divert to Chile or similar.

I was also impressed with the way you started to see sea ice and icebergs on the way into Antartica, that was a pretty good effect to build into Antartica X.
