On September 28, 1924, aircraft appeared over Seattle and descended toward Sand Point. The machines had left the city 175 days earlier to attempt something no airplane expedition had completed: a circumnavigation of Earth. The crews returned after crashes, forced landings, engine changes and an ocean crossing. Two original Douglas World Cruisers—Chicago and New Orleans—had flown all the way around the world.

Planning a route around an unfinished air world
Long-distance aviation was still young. Aircraft had crossed the Atlantic, and military flyers had demonstrated continental range, but a global circuit required very different endurance. There was no worldwide network of modern airports, reliable radio navigation or standardized maintenance. A successful expedition would need airplanes that could use land fields and water, plus a chain of fuel, spare parts, mechanics, ships and diplomatic permissions.
The U.S. Army Air Service commissioned Douglas to adapt its DT torpedo aircraft into the Douglas World Cruiser. The design carried extra fuel and could exchange wheels for floats. Four aircraft received geographic names: Seattle, Chicago, Boston and New Orleans. Each carried a pilot and mechanic. Major Frederick Martin commanded the expedition at departure; after his aircraft was lost, Lieutenant Lowell Smith led the continuing flight.
West from Seattle
The official circumnavigation began from Seattle on April 6, 1924. The route headed northwest through Alaska and the Aleutians before crossing toward Japan. Flying west had strategic logic: it followed a chain of prepared support points and allowed the crews to change between floats and wheeled landing gear as geography demanded.
The first major loss came early. Seattle developed engine trouble and fell behind. While trying to rejoin the formation, Martin and Staff Sergeant Alva Harvey became lost in fog and crashed into an Alaskan mountainside. They survived and reached safety, but the expedition continued with three aircraft. The accident demonstrated the margin separating a navigational error from catastrophe.
Across Asia and Europe
Chicago, Boston and New Orleans crossed Japan, China, Southeast Asia, India and the Middle East before entering Europe. Descriptions of the flight sometimes reduce this part of the route to a line on a map. For the crews, each line represented weather judgment, fuel calculation, unfamiliar landing conditions and the possibility that a small mechanical defect could stop the entire attempt.
The achievement was also geopolitical. Permissions and support had to be arranged across territories governed by empires, kingdoms and republics. Because the United States did not recognize the Soviet Union, the planners avoided a Siberian route and took a much longer path through southern Asia. The map reflects diplomacy as much as aircraft range.
The Atlantic nearly ends the attempt
The flyers reached Europe and continued north for the staged crossings of the North Atlantic. Between the Orkney and Faroe islands, Boston lost oil pressure and came down on the ocean. The crew was rescued, but the aircraft was damaged beyond recovery while being handled at sea. Only Chicago and New Orleans remained from the formation.
A prototype aircraft was prepared as Boston II and joined them in Nova Scotia. It could accompany the final stages and share the public return, but it had not flown the complete circuit. That distinction matters when counting the first aircraft to circumnavigate: Chicago and New Orleans completed the entire route.
Home across the United States
After the Atlantic crossing, the flight became a westward journey through American cities. Public welcomes celebrated a technical achievement and advertised the possibilities of aviation. The final leg returned to Seattle on September 28. Contemporary photographs record aircraft, crews and crowds at Sand Point, but no single image can contain the six months of preparation and accumulated repair behind the landing.
The official distance was about 27,553 miles, or 44,085 kilometers. The expedition took 175 days, of which 371 hours and 11 minutes were flying time. The contrast between those numbers reveals early global aviation: the aircraft spent far more time waiting, maintaining, refueling and positioning than moving through the air.
What made the flight possible
The pilots and mechanics faced danger directly, but the circumnavigation was a national logistical project rather than an unsupported adventure. The Army Air Service planned the route; the Navy and Coast Guard positioned vessels; engines, fuel and parts waited at distant stops; diplomats secured access. The World Cruisers were repairable because a supply system had been built around them.
That system is part of the historical achievement. Aviation’s future depended not only on longer-range aircraft but on networks that made repeated long-distance operation possible. The 1924 expedition demonstrated what such a network might look like before commercial air routes crossed the globe.
After the cheers
The Chicago entered the Smithsonian collection and survives as material evidence of the flight. The New Orleans also survives in a museum collection. Their preservation allows historians to examine the practical modifications—fuel capacity, cockpit arrangements and interchangeable landing gear—that written celebrations can overlook.
The flight did not immediately create routine global passenger service. It did compress the imaginable scale of aviation. A journey around Earth had moved from proposal to demonstrated route, completed by aircraft that could be maintained across multiple climates and political borders.
Why September 28 matters
The landing at Seattle was both an ending and a proof. The expedition had lost two original aircraft yet no crew member on those aircraft was killed. It adapted, replaced engines, changed undercarriages and continued after setbacks that might have ended a less-supported attempt.
The first aerial circumnavigation is therefore best understood as endurance plus infrastructure. The heroic image of a biplane above an ocean is real but incomplete. Behind it stood charts, depot ships, mechanics, permissions, stored fuel and thousands of decisions made before and during the route.
The crews behind the aircraft names
Seattle carried Major Frederick Martin and Staff Sergeant Alva Harvey. Chicago was flown by Lieutenant Lowell Smith with Lieutenant Leslie Arnold as mechanic; Boston by Lieutenant Leigh Wade and Staff Sergeant Henry Ogden; and New Orleans by Lieutenant Erik Nelson and Lieutenant John Harding Jr. The two-person crews divided navigation, flying and mechanical work under conditions that offered little redundancy.
After Martin’s crash in Alaska, Smith assumed command. Leadership change was only one adaptation. Engines were replaced, damaged fittings repaired and routes adjusted around weather. The mechanics were not passengers: the entire project depended on diagnosing aircraft far from a home factory and coordinating replacement parts with the support network.
Navigation before electronic certainty
The World Cruisers flew before satellite navigation and modern air-traffic control. Crews relied on charts, compasses, visual landmarks, weather reports and dead reckoning. Over water, ships stationed along difficult legs could provide weather, rescue capacity and reference points. Fog could erase land and horizon together, as the loss of Seattle demonstrated.
The aircraft also moved between operational identities. Floats allowed landings on protected water where runways did not exist; wheels reduced drag and served established fields. Changing undercarriage took equipment and labor at prepared locations. Global range was achieved not by one perfect configuration but by a machine designed to be reconfigured along the route.
Public spectacle and military purpose
The return across the United States drew crowds because the expedition offered an optimistic picture of shrinking distance. Newspapers could present aircraft arriving from places that many readers knew only from maps. The Army Air Service also had an institutional purpose. Demonstrating long-range aviation supported arguments for resources, technical development and a larger role for air power inside the military establishment.
Those aims do not diminish the achievement; they explain why such extensive support existed. Record flights often combine exploration, publicity and bureaucratic competition. The World Flight proved capability to the public while giving the Air Service experience in logistics, navigation and international coordination. The preserved Chicago is therefore both an engineering artifact and evidence of aviation’s political ascent.
The route was not the geometrically shortest line around Earth. It followed places where fuel, repair, landing water or fields and political permission could be secured. Geography was filtered through empire: many stops lay in colonial territories, and American diplomatic access reflected the international power system of the 1920s. The flight’s triumphal narrative can coexist with recognition of that unequal landscape.
Weather information was similarly uneven. Crews sometimes waited days for conditions that could be judged acceptable from sparse reports. Forecasting over oceans and remote coasts lacked today’s satellite observations. Delay was therefore a safety tool rather than evidence of failed planning. The 175-day duration records prudence, maintenance and uncertainty as much as airspeed.
The expedition also generated photographs, film, logs and press accounts that turned technical work into public history. Those records let historians separate the full-circuit aircraft from substitutes and ceremonial participants. They also show how a record is constructed socially: officials defined the route and measured the distance, newspapers narrated progress, and museums later selected objects that would stand for the whole journey.
