English Army Captain Preet Chandi has become the first woman of color to ski alone to the South Pole. CBS News correspondent Roxana Saberi caught up with her in London after Chandi returned from the treacherous mission faced by few "polar explorers" before, where she endured temperatures down to 60 below zero and 60-mph winds.
