Today that I finished most of McMurdo's files I used to opportunity to take an A319 on a flight to McMurdo (this type of aircraft is actually flying there). Please keep in mind that I'm not even close as good as Nick in taking screenshots.
Southeast of Terra Nova Bay...

...Mount Erebus in the background.

Mount Erebus is a volcano that has one of only three open lava lakes on earth - the other two being in Congo and Ethopia.

Passing Mount Erebus. Note that all the screenshots you have seen up to here show
Antarctica X in "default". The
complete continent is covered in this quality while there are a few areas (mainly around the bases) that are done in even higher quality.

Overflight of McMurdo's Sea Ice Runway

Touching down (as seen from the Tower)

Taxiing along "Fuels".

Note the large engine heaters that are used down here warm up the engines before startup

Parking brakes set, engines turned off. A passenger is disembarking from the Hercules in front of us. Note the snow animated blower clearing the apron of snow
Just a little tour but I hope you like it.
Bests,
Sascha
