Reykjavik, Iceland, where they fortuitously met Italian Antonio Locatelli and his crew, also in the course of the same circumnavigation attempt, and there accompanied by five navy vessels and their 2,500 seaman, the Chicago, with Smith and Arnold still in the lead, and the New Orleans, with Nelson and Harding, continued on for Fredricksdal, Greenland. This was to be the longest leg of the entire journey, with those five vessels strung along the route. New engines were installed on arrival at the second stop in Greenland, Ivigtut. On 31 August, they reached Labrador, Canada, a fuel-pump failure in the Chicago having been overcome by four hours of hand pumping by Arnold. After the original prototype, now named Boston II, arrived in Pictou, Nova Scotia, the original Boston crew of Wade and Ogden were able to join the other two aircraft to fly on to Boston (where pontoon floats were exchanged for wheels again) and Washington DC. After a hero's welcome in the capital, the three Douglas World Cruisers flew to the West Coast, on a multi-city tour, stopping, on 22 September, at Rockwell Field, San Diego, for new engines and then arrived in Santa Monica to a welcoming crowd of 100 to 250 thousand. Their final landing in Seattle was on 28 September 1924. The trip had taken 363 flying hours 7 minutes, over 175 calendar days, and covered , succeeding where the British, Portuguese, French, Italians and Argentinians failed. The Douglas Aircraft Company adopted the motto, "First Around the World – First the World Around". The American team had greatly increased their chances of success by using several aircraft and pre-positioning large caches of fuel, spare parts, and other support equipment along the route. They often had several US Navy destroyers deployed in support. At prearranged way points, the World Flight's aircraft had their engines changed five times and new wings fitted twice. Itinerary The flight traveled from East to West, beginning in Seattle, Washington, in April 1924 and returning to its start point in September. It flew northwest to Alaska across northern-Pacific islands to Japan and then south-Asia, across to Europe and the Atlantic Ocean. The route's most southerly point was Saigon (10 deg N) and only briefly south of the Tropic of Cancer, the refueling stops being: United States: Sand Point, Lake Washington, Seattle, Washington 6 April 1924 Canada: Seal Cove, Prince Rupert, British Columbia Alaska: Sitka,
