A319 Lands on Antarctic Ice Runway
If it was a charter Convair in the late 1960s chances are it was Modern Air, they went from the US to all sorts of oddball places, and were the first US operator to set up jet holiday charters from West Berlin. I remember a photo of one of their Convairs around this time in Easter Island, South Pacific, when only an intermittent LAN Chile DC6 was the other traffic.
