The great circle route tracks north over British Columbia and the Canadian Rockies, then across the southern tip of Greenland or Iceland depending on winds, over the Norwegian Sea, across Scandinavia (likely southern Norway and Sweden), then south through Denmark and northern Germany into Berlin. At cruise altitude over Greenland the ice sheet is visible as a vast white expanse; over Scandinavia forested terrain and fjords are visible in clear conditions.
