Tingmissartoq and the 1933 Global Survey for Commercial Aviation
In the early 1930s, the dream of seamless international air travel required more than just ambition; it required precise data. To turn this vision into reality, several of the world's leading airlines—including Pan American Airways, Imperial Airways, Deutsche Luft Hansa, KLM, and Air France—collaborated on a comprehensive study of potential international air routes. This initiative aimed to map the skies across the North Atlantic and South Atlantic to facilitate the growth of commercial air transport.
Pan American Airways was tasked with surveying the route from Newfoundland to Europe via Greenland. To lead this critical mission, the company appointed Charles Lindbergh as its technical advisor. On July 9, 1933, Lindbergh and his wife, Anne, departed from New York City in the rebuilt aircraft known as Tingmissartoq, embarking on a journey to gather essential geographical and meteorological data.

For this ambitious expedition, the aircraft underwent significant upgrades to ensure safety and precision over vast, uncharted distances. The cockpit was equipped with a Sperry artificial horizon (an instrument that provides the pilot with a visual representation of the aircraft's attitude relative to the horizon) and a directional gyro to maintain a steady course.
Power was provided by a new Wright Cyclone SR1820-F2 engine, delivering 710 hp. To maximize range, gasoline tanks were installed in every available space, including the wings and floats. Additionally, the aircraft was stocked with extensive emergency equipment to prepare the crew for the possibility of a forced landing in remote regions.
The Global Expedition
Logistical support was a priority for Pan American. The company hired a Danish ship, the Jellinge, to maintain radio contact with the Lindberghs as they navigated the treacherous waters near Labrador, Greenland, and Iceland. The ship also coordinated the delivery of advance supplies to key waypoints, including Halifax, St. John's, Cartwright, Greenland, and Iceland.
The journey began with a flight from New York to Hopedale, Labrador, following the eastern Canada–US border. From there, the couple completed their first major over-water leg, a 650-mile flight to Godthaab. After crisscrossing Greenland to Baffin Island and returning, they flew to Iceland.
The mission then expanded into a global tour. The Lindberghs visited major European cities and Moscow before traveling down the west coast of Africa. They crossed the South Atlantic to South America, flew along the Amazon River, and turned north through Trinidad and Barbados. By the time they returned to New York on December 19, they had traveled 30,000 miles, visited 21 countries across four continents, and provided invaluable data for the planning of transatlantic air routes.

Following its service, Tingmissartoq became a piece of aviation history. It was displayed at the American Museum of Natural History in New York City until 1955. It then moved to the National Museum of the United States Air Force in Dayton, Ohio, before being transferred to the Smithsonian Institution in 1959. Today, it remains on display in the "Pioneers of Flight" gallery of the National Air and Space Museum.
