1924 Douglas World Cruiser "Seattle"

Seattle 3/4 Seattle Side

This aircraft was one of four biplanes owned by the US Army Air Service that attempted the first flight in history to circumnavigate the globe. The "Chicago" and the "New Orleans" completed the trip. The "Seattle" crashed near Port Moller on the Alaska Peninsula. The "Boston" crashed in the Atlantic between the Faroe Islands and Iceland. The crew was rescued, but not the plane.

Donald Douglas with the help of his engineer Jack Northrop, modified the design of the Douglas DT-2, a torpedo plane, ending up with the World Cruiser. There were a total of six fuel tanks in the wings and fuselage. The total fuel capacity of the planes went from 115 gallons to 644 gallons. They increased the cooling, and two different radiators were used, depending on the climate. Oil and water tanks were added. They strengthened the fuselage, modified the wings and enlarged the rudder.

Spare parts were sent ahead of the expedition including 15 Liberty engines and 14 sets of pontoons.

The wreckage was retrieved in 1967 through the efforts of Bob Reeve to go on display in the Centennial Aviation Museum that burned in 1973. The "Seattle" wreckage survived the fire and is now displayed at the Alaska Aviation Heritage Museum courtesy of the Alaska State Museum in Juneau. The "Chicago" is at the National Air and Space Museum. The "New Orleans" at the Museum of Flying, Santa Monica, California.

Last Flight for Douglas World Cruiser Seattle

April 30, 1924

When Seattle failed to arrive in Chignik on April 30th, naval ships Algonquin and Haida, coastal steamer Pioneer, began to search the area. Martin and Harvey had encountered strong head winds and snow squalls, limiting visibility with white-out conditions. Seattle's flight came to a violent end, hitting the crest of a 700' hill, and sliding another 100'. Miraculously, her crew survived with only minor injuries. They gathered some food and emergency supplies and made camp near the wreckage, waiting for the storm to end.

Realizing that it would be more difficult to be rescued on the hillside, the flyers decided to hike to the beach. Rough terrain and snow made this a dangerous trek, lasting over a week. At last they reached a trapper's cabin across the bay from Port Moller. Food and shelter gave the men strength to hike another twenty miles the following day. Finally, they were picked up by natives in a dory and taken to Port Moller, arriving on May 10th. The cannery superintendent for Pan American Fisheries radioed the good news of their safe arrival, ending the search. The men were ordered to report back to Washington, D. C., as soon as possible.

Lt. Lowell Smith now led the flight with the Chicago on May 3rd as the three remaining Douglas World Cruisers sped on toward Asia, the Mid-East, Europe and the United States. On September 28, 1924, this record setting flight was achieved, when the Douglas World Cruisers landed at Vancouver Barracks, Vancouver, Washington.
