From the warmest deserts, to the coldest, snow-covered north and south poles, the DC-3 has been everywhere. Traveling at 170 miles per hour (274 km/h), Buffalo Airways DC-3s can haul 6000 pounds of freight to destinations throughout the Canadian North. That is not to say that these aircraft always stay close to home, as they have flown from one end of Canada to the other, south into the United States, and as far north as Greenland. The Douglas DC-3s at Buffalo Airways normally operate on wheels, but when it comes time to land on the snow-covered lakes of the Canadian North, some of the aircraft have the wheels removed, and replaced with skis. As well, although Buffalo does not operate any DC-3s on floats, some were operated on floats in the military to allow landing directly on the water. The Douglas DC-3 is truly a versatile airplane.
