AT THE MERCY OF THE WINDS tells the extraordinary stories of both journeys. Featuring up-to-the-minute drama from David's own expediton and original photographs and documents from the Swedish voyage, it is the ultimate adventure book as, alone in the skies above a frozen and harshly beautiful landscape, David battled against the elements to fulfil the drama of three Swedith explorers a century earlier, and become the first man to balloon to the North Pole.
