Designed to explore harsh Antarctic conditions, the Snow Cruiser was built in 1939. It was 55 ft. long, 18 ft. wide, 16 ft. tall, and weighed 37 tons. The 700 lb. tires, each 10 feet tall, were designed to carry the Cruiser at a top speed of 25 MPH. The vehicle was powered by two six-cylinder, 672 cubic inch, 150 hp Cummings Diesel engines. It also featured a single-engine Beechcraft airplane, carried on the top.
The Snow Cruiser was taken to the South Pole by Admiral Byrd in late 1939. Unfortunately, the vehicle's great weight made it sink into the snow, and it had to be abandoned. Clive Cussler's adventure novel "Atlantis Found" actually used the Snow Cruiser to help save the world. Read the History of the Snow Cruiser. Cross-sections and photos HERE and HERE.
