A two seat version of the Gamma 2A, the Polar Star attempted the world's first trans-Antarctic flight on November 23, 1935. Explorer Lincoln Ellsworth and Canadian pilot Herbert Hollick-Kenyon left Dundee Island for Little America station but ran out of fuel on the last leg of the journey 25 miles short of Little America. They walked that last distance and settled in the abandoned camp until rescued two months later. The airplane was later recovered and donated to the Smithsonian.
