I did a flight to JNB recently where the route took us around the edge of Antarctica in the vicinity of the Australian bases. We were lucky to have large areas of clear sky (normally overcast) and had spectacular views of the coast as well as Pack Ice and Icebergs of all sizes. Spoke briefly to some pilots flying a C212 down there - were counting Minke whales at the time. We got the impression that the flying tasks varied daily and sounded like a great job in a really spectacular part of the world.
I can understand why Croydon Travel are able to successfully market these Antarctic Charters as it is a once in a lifetime experience for most people.
Happy New Year PPRuNers.
