1924 First Successful Circumnavigation Flights

A DigitalThemePark Achievement

On April 6, 1924, four pilots and four copilot/mechanics left Sand Point on Lake Washington near Seattle in four aircraft for a 175-day westward circumnavigation of the planet. It was the first successful circumnavigation of the globe with a 100-year anniversary just two years from this writing. Only two planes and crews finished the route. One aircraft got separated from the others by a thrown rod early in the flight but crashed into a mountain in Alaska while trying to catch up (the crew survived). The other aircraft capsized and was lost while under tow after losing power near the Faroe Islands. The two remaining aircraft flew the entire route and returned to Sand Point, Washington on September 28, 1924.

Lots of background information on the original flights:

A diary of the original flight with lots of details about each leg is available here with some interesting and useful information:

There are also a couple wanting to re-create the historic flight starting in 2023. They have lots of info on their website:

The original flight used modified WWI Douglas DT-2 torpedo bomber open-cockpit biplanes powered by a single 450 HP Liberty 12, normally-aspirated engine. The DT-2 had a top speed of 100 mph and a service ceiling of 7,400 feet. The planes were equipped with both floats and wheels and could be configured to land on land or water. A number of the stops along the route were on the water but these flights use nearby airports so the entire flight can be completed using conventional gear aircraft.

Many of the cities where the original crews laid over and performed repairs have changed names, countries have changed, and some airports don’t even exist anymore or never really did exist. Two notable examples of airports that disappeared were the official start/finish at Sand Point, Washington (now a park), and Bolling Field (now light industrial and park across from Reagan National). Instead, this route uses Boeing Field as the start/finish and Reagan National as the Washington, DC stop.

Special Directions:

  • This route tries to be as faithful to the original route as possible given how much can change in 100 years. Some are now international airports and some are very minimal and not even paved. There are long overwater legs, a short 36nm resupply leg, and stops in some interesting countries along the way. In general, faster aircraft that are happy to fly low for sightseeing and can set down on short, unimproved runways are going to be good but be mindful of the airports for each leg. You may get there but not be able to stop. All airports on this route are available in MSFS in this writing:
    • Feel free to adjust waypoints if you fly larger aircraft but if you land there, you take off there. Any adjustments to waypoints have to stay within 100nm of the true waypoint.
  • The flight technically started at the Douglas Aircraft factory in Santa Monica, CA (KSMO) with three shakedown legs to get the aircraft to the official start ceremony at Sand Point, WA.
    • Those are optional but listed in the itinerary if anyone wants to shake down an airplane before the official start. (See the achievement requirements below.)
    • Likewise, the route maps don’t show the diversion by the last two aircraft to Rockwell Field on the north end of Coronado Island at San Diego for engine changes, but that’s included in this route since the planes actually did that.
    • Also of note, when the two remaining aircraft returned to the US, there was a tour of some 16 US cities on the way back to Seattle, WA. All leg endpoints are listed in the itinerary.
  • The four original crews were limited to one airplane each though there were a number of engine changes along the route. To approximate these restrictions with a nod to practicality:
    • Pilots are limited to three different aircraft, per “region” from the official start departing Boeing Field.

Note: There may be advantages to sticking with one or two aircraft for longer in case you’d like to use a plane not yet available or want to get a feel for a long-legged flight before making a commitment. If you want more of a challenge, try to do the full route in a single aircraft. Keep the long-distance legs in mind when you choose your aircraft. Some are over water with no airfields along the route to refuel. It’s looking like planes that perform similar to WWII fighter aircraft may be good. One group (Got Friends) did a similar route in the Flying Iron Spitfire but not sure how they handle the really long legs. If you like WWII planes, the Flying Iron P-38 is looking very capable. It’s fast (over 400 mph, cruise in the 300s), has a service ceiling of 44,000 feet, and the Fowler flaps can help bring it in tight on short runways, but feel free to pick what suits you. It’s not a race but an achievement – and a big one. If you do this, you will have circumnavigated the planet.
