Byrd's Expedition Flies Over the South Pole

In Brief

Richard Byrd's expedition flew over the South Pole on November 29, 1929. Pilot Bernt Balchen and the other crew members shared in the achievement. The flight required navigation across Antarctica and a difficult route over the continent's mountains. It formed part of a larger expedition supported by a coastal base and many workers. Aviation over the pole was not the first human arrival there; ground expeditions had reached it earlier.

An Aircraft Crosses the South Pole

On November 29, 1929, an American expedition led by Richard E. Byrd made the generally credited first flight over the geographic South Pole. Byrd served as navigator aboard the Ford Trimotor Floyd Bennett. Bernt Balchen piloted, with Harold June and Ashley McKinley also aboard. Calling it Byrd's flight can be useful shorthand for the expedition, but it should not erase the people responsible for flying, radio work and photography. Nor was this the first time people had reached the pole. The achievement was to cross it from the air and return safely to the expedition's base.

A Departure From Little America

The expedition worked from Little America on the Ross Ice Shelf. An airplane still needed fuel, maintenance, weather information and a suitable place to take off. Antarctic isolation made those requirements part of the expedition rather than services that could be bought at a nearby airfield. The route went toward the plateau across mountainous terrain. Altitude mattered because the aircraft had to climb with people, equipment and fuel while retaining enough power and margin to continue. The distance to the pole was not the only measurement governing what could be carried.

How a Crew Identified a Point Without a Runway

An aircraft could cross the geographic point without seeing a landmark exactly beneath it. Navigation therefore required observations, course calculations and estimates of progress under changing conditions. The expedition's records and photographs help establish the route and the work done aboard. An overflight does not create a camp or place people on the surface. That difference matters when comparing the flight with Amundsen's and Scott's journeys. Each method answered a different question about travel in Antarctica, and each required a different way to verify arrival.

What an Aircraft Added to Exploration

Flight could carry people over a route much more quickly than a surface expedition, while also offering a view of terrain difficult to survey from the ground. It brought its own risks and dependence on support. The November flight demonstrated that an aircraft could be used to reach an extreme inland point and return, not that ground expeditions had become unnecessary. Aviation expanded the range of observations available to polar researchers. The expedition's result belongs to that change in method as well as to the record of firsts.
