On February 21, 1924, Carl Ben Eielson flew Alaska’s first official air mail service. The 280-mile flight from Fairbanks to McGrath took just a few hours, compared to 18 days or more by dog sled. Eielson used a de Havilland DH-4 open cockpit biplane to carry the 164 pounds of mail, and he bundled up in caribou-fur socks, moccasins, a reindeer parka, a marten-skin cap, a wolverine-skin hood, and multiple wool layers, as well as goggles.
