Were you at Belgrano? I flew over there a few times on depot-laying flights from Halley. The first couple of times people even came out and waved.
Unfortunately that (and occasional radio darts with SANAE and Showa) was the closest I got to visiting another country's base in my two years.
I was at Halley 5, the remains of which are probably part of a new iceberg: https://news.ycombinator.com/item?id=34578468
