How many pairs of thermals would you need to travel to the South Pole?

3-pair of thermals, plus 2 boots, 4 cases of chap-stick, 17 pairs of socks, 6 cases of Spam, and 14 rolls of TP.
Won't happen as thermals providing lift to pilots are air currents drawn into a spin lifting surface heat. Polar ice reflects heat. Icy wind won't be spun up by excessive warmth. Gliders and other craft use thermals in warmer regions to travel a long distance from high altitude.
