There was a tree in Antarctica '89, a couple before and one after that I know of. Hut 7 was the CPO's, hut 8 the O's, the hut with the flag was the gym

We had every thing down there in '90, a German Dornier with skies pictured above. Also had the standard Kiwi 130's, German 130's, Italian 130's (no helos), and we even had a Canadian Otter with skies.

The above flag was the "Herc" flag, twas run up the mast whenever all the 130's were in an up status. A helo with circle and slash and the words "not on my ice." There was a great rivalry between the helos and hercs (a good one) that provided a little diversion and entertainment. 

All six of the damn things invaded the herc space. They came down to the ice runway to see if they could use the helo hanger pictured.

A closer look. I don't know if they got the plans from lockheed or if lockheed got the plans from them.
Had to communicate with hand signals and pictures/drawings to find out what they needed for maint support.

Taken through binoculars from maint control, ice runway, looking under a 130 wing '90.
