Neither uphills nor downhills today: the going was slick and smooth; visibility was partial whiteout. We set a good pace throughout the day, and traveled a respectable 28.3 km. Rest day proved restorative: the men were fighting fit, and biting at the bit. At about four o'clock local time (GMT -6 hrs) we heard an aircraft overhead. Probably, it was a Kenn Borek De Havilland Twin Otter. What its mission was we do not know. Distance remaining to the Pole: 260 km Skiing days remaining: 9 All is well with the Expedition.
