I have turned my attention to legs beyond the first one, specifically to legs 2, 3, and 4. Leg 2 should be a trip to the Atacama Desert of northern Chile. There are 3 possible airports there: Arica, Iquique, Antofagasta. The highest probability (by a small amount) of these three goes to Antofagasta, which is a mere 600 miles by road from Santiago. That opens up the possibility of a long bus or self-drive trip to begin leg 3; it also might be a flight to Santiago. The rest of leg three will be a flight from Santiago to Punta Arenas, Chile. The most logical next step is a flight to King George Island(Isla Rey Jorge), which is 100 miles off the Antarctic Peninsula, and overnight there followed by a return to Punta Arenas. Given the times and distances involved this could mean a double leg. For leg 4, from Punta Arenas there is a 3 times per week one hour LAN flight or a twice per week 11 3/4 hour bus involving crossing the Straight of Magellan to get to Tierra del Fuego and Ushuaia, Argentina. The one thing that is certain (beacuse van Munster said so) is a trip to the bottom of South America. That is Cape Horn, Chile, a national park on an island and it is about 125 miles south of Ushuaia. The teams would have to do that by boat or helicopter. After returning to Ushuaia, then you can fly out to get to southern Africa. My guess is that the flights connect through Buenos Aires.
