Prior to the 1955-58 Commonwealth Trans Antarctic Expedition (CTAE), led by explorers Sir Vivian Fuchs and Sir Edmund Hillary, no other expedition had ever successfully crossed the Antarctic via the South Pole. In keeping with the “Heroic Age” of exploration, part of the CTAE’s purpose was to carry out scientific research. This included seismic soundings and gravimetric readings, which were done as part of the International Geophysical Year. Along with a few other vehicles, the Tucker Sno-Cat was selected as the primary vehicle by Transport & Engineering Officer David Pratt, after hearing about the success Tucker had with the military during and after World War II. Our Trans Antarctic Expedition Design Poster, part of our Extraordinary Vehicle series, took nearly 300 hours to produce and was custom designed in partnership with the Tucker Sno-Cat Corporation.
