another photo taken at Sky Blu and it's a close up of the aircraft runway
there. The British Antarctic Survey are able to land wheeled as well as
ski planes at Sky Blu because climatologically the place is pretty windy
which means that snow tends to blow away exposing a blue coloured ice sheet
which it turns out planes can land on OK! The photo shows you what a blue
ice runway looks like. Except it's supposed to be bluer and slightly less
snow-covered - when I was there it hadn't been windy in a little while!
