The Nineteen Twenty-Four World Flight, the Douglas World Cruisers, and the Eight Men Who Proved an Airplane Could Circle the Globe

On April 6, 1924, eight men climbed into four open-cockpit biplanes at Sand Point on Lake Washington in Washington State and flew west. One hundred and seventy-five days later, they landed back where they started - the first human beings to circumnavigate the globe by aircraft. No one had done it before. No blueprint existed for doing it. They wrote the procedures as they went.

What Was the 1924 Army World Flight?

The 1924 World Flight was a mission conceived and executed by the U.S. Army Air Service as a strategic demonstration of American aviation capability. The First World War had ended only six years earlier, and the Army needed to make the case that aviation was a serious military asset - not a novelty, but a technology with global reach.

Britain and Italy were both pursuing long-range aviation ambitions. The Army calculated that if American aircraft could navigate the Aleutian fog banks, the Indian monsoon, and the North Atlantic ice, they could go anywhere. The mission was equal parts proof of concept and geopolitical statement.

What Were the Douglas World Cruisers?

The Army turned to Donald Douglas, a 31-year-old engineer running a small aircraft company out of a converted movie studio in Santa Monica, California. Douglas Aircraft was barely two years old, but Douglas himself had trained at MIT and under Glenn Martin, and he was trusted immediately.

The Douglas World Cruiser was a heavily modified version of the DT-2, a Douglas torpedo bomber already in Navy service. The wings were widened. Fuel capacity was expanded for long overwater legs. Most crucially, the landing gear was designed to swap between wheels and pontoons - the route required both.

Power came from the Liberty 12, the 12-cylinder liquid-cooled engine developed during the war, producing approximately 400 horsepower. It was proven, reliable, and rebuildable in the field with basic tools. Cruise speed was around 85 mph, with a loaded range on floats of roughly 1,100 miles.

Douglas built five aircraft: one prototype and four operational machines. The operational aircraft were named after American cities: Seattle, Chicago, Boston, and New Orleans.

Who Were the Eight Men?

Two crew members flew each aircraft - a pilot and a mechanic.

Major Frederick Martin commanded the expedition in the Seattle. His mechanic was Sergeant Alva Harvey. As the senior officer, Martin held overall command of the flight.

Lieutenant Lowell Smith flew the Chicago with Staff Sergeant Leslie Arnold. Smith was the steadying presence the other crews relied on - calm under pressure, precise, and methodical through conditions that demanded all three.

Lieutenant Leigh Wade flew the Boston with Staff Sergeant Henry Ogden. Wade was meticulous about his aircraft’s mechanical condition in a way that served him well when the machines started showing wear.

Lieutenant Erik Nelson flew the New Orleans with Sergeant Jack Harding. Nelson brought an engineer’s depth of understanding to aircraft systems, which would matter when things failed - and things would fail.

How Did the Flight Begin, and What Went Wrong in Alaska?

The four aircraft departed Sand Point on April 6, 1924, climbing out northwest toward Alaska. The route called for them to work up the Alaskan coast, traverse the Aleutian island chain, and cross to Japan.

Alaska nearly ended the expedition in its first month. The coastline along the Alaska Peninsula in spring operates under near-constant overcast - ceilings of a few hundred feet, fog that moves in within minutes, mountains running directly to the water’s edge with no emergency landing options anywhere.

On April 30, Major Martin was leading the formation along the coast near Chignik when the weather closed in. He descended to stay visual, reading the terrain. The ceiling dropped faster than he could read it.

The Seattle flew into a mountainside.

The aircraft was destroyed. Martin and Harvey survived the impact and spent the next nine days in the Alaskan wilderness before a rescue party from a nearby cannery reached them. The expedition had lost its commander and one of its four aircraft before leaving North America.

Lowell Smith assumed command. The decision was made to press on with the remaining three aircraft.

What Made the Aleutians So Dangerous?

The Aleutian Island chain stretches 1,300 miles from the Alaska Peninsula toward Japan across the North Pacific. In 1924, it was one of the most consistently hostile flying environments on earth.

Weather there is driven by the collision of Arctic and Pacific systems and changes in minutes, not hours. Williwaws - sudden violent gusts off the mountains - can flip a floatplane before a pilot can react. The islands were not charted in useful detail at the time. Support ships were prepositioned at critical points, but there were stretches where the three crews were entirely on their own.

They crossed the Aleutians and reached Japan.

How Did the Route Unfold Across Asia and Europe?

The Imperial Japanese Navy received the crews with formal ceremony. But every day on the ground was a day not covering distance, and the crews knew it.

The route continued south through Japan, then to Shanghai, Hong Kong, and Saigon. Tropical heat pushed the Liberty engines harder than they had been designed to run. The mechanics monitored oil temperatures continuously and changed oil more frequently than any manual specified, because no manual had been written for this.

By Calcutta, the monsoon was building. Every fitting, cable, and fabric panel on the aircraft reflected what they had been through. The crews carried spare parts and patched as they went. Through Karachi, Baghdad, and Constantinople - already being renamed Istanbul under Atatürk’s new republic - the Bosphorus below, Europe and Asia meeting at the water’s edge.

The flight reached Paris on July 14 - Bastille Day - and then London, before heading north to the Orkney Islands off Scotland’s northern tip. The North Atlantic was ahead.

What Happened Over the North Atlantic?

On August 3, departing the Orkneys for the Faroe Islands, Leigh Wade watched the oil pressure on the Boston’s Liberty engine begin to drop. He nursed the aircraft to the Faroes, reading the gauges the whole way. The engine was finished.

A support ship hoisted the Boston aboard. Wade and Ogden were unharmed, but there were now two aircraft - Chicago and New Orleans - where there had been three.

The Army had kept one reserve World Cruiser on standby in England. Wade and Ogden were flown to Pictou, Nova Scotia, where they would rejoin the flight in a replacement aircraft - also named Boston - after Smith and Nelson crossed the Atlantic.

The crossing from Iceland to Greenland alone covered nearly 800 miles of open ocean, with the Greenland ice cap making any forced landing option academic. Smith and Nelson picked their weather carefully, navigated by chart and compass, and on August 31, they landed in Labrador.

They had crossed the North Atlantic by the northern route - island by island through ice and fog - and no one had done it before them.

How Did the Flight End?

From Labrador, the two aircraft flew south. In Nova Scotia, Wade and Ogden were waiting with the replacement Boston. Three aircraft formed up together for the first time since the Faroes and flew south.

President Coolidge came out to meet the crews in Washington, D.C.. Speeches were made, honors given. The men had been flying for nearly five months and stood in their worn flight suits looking, by contemporary accounts, somewhat dazed.

They were not finished. The route continued south to New Orleans, west across the country, and then north to Dayton, Ohio, where they circled Wright Field - named for the brothers who had made the entire enterprise possible. That stop was deliberate.

On September 28, 1924, Chicago, New Orleans, and the replacement Boston landed back at Sand Point in Seattle.

What Were the Final Numbers?

The statistics of the 1924 World Flight deserve to be held next to the technology that produced them:

175 days total elapsed time
27,553 miles covered
371 hours of actual flying time
74 stops across 28 countries
No fatalities

Open cockpits. A war-surplus engine design. Charts that were imprecise over large stretches of the route. Weather reporting that provided almost no useful advance information. These were the tools available.

Why Does the 1924 World Flight Still Matter?

The flight proved, on a global scale, that aviation was a technology with real reach. The skeptics needed that demonstration, and the Douglas World Cruisers provided it.

Donald Douglas did not stay small for long afterward. The contracts came. The DC-3 followed in the next decade and became the backbone of commercial aviation worldwide. A direct line runs from those four biplanes on Lake Washington to every airliner Douglas ever built.

The Chicago survived the flight and is preserved at the Smithsonian’s National Air and Space Museum in Washington, D.C. The cockpit and engine are visible. The engine alone - a Liberty 12, designed for a war that ended in 1918 - flew the entire circumference of the earth.

Key Takeaways

On April 6, 1924, four Douglas World Cruisers and eight Army Air Service aviators departed Seattle on the first successful around-the-world flight, returning September 28, 1924.
The mission covered 27,553 miles across 28 countries in 371 hours of flight time, with no fatalities.
The Seattle was destroyed in an Alaskan mountainside crash on April 30; the Boston was lost to engine failure near the Faroe Islands on August 3 - both crews survived.
Lieutenant Lowell Smith assumed command after Major Martin’s crash and led the expedition to completion.
The flight directly shaped Douglas Aircraft’s trajectory; the company’s later work, including the DC-3, grew from the credibility established in 1924.
The surviving Chicago is on permanent display at the Smithsonian’s National Air and Space Museum.
