Three and a half years after his death, another of Microsoft co-founder Paul Allen’s passion projects — the extensive collection of aviation and military artifacts that housed at the Flying Heritage & Combat Armor Museum in Everett, Washington — has reportedly been sold. close to his estate.

Air Current magazine reported late last week that the museum’s entire collection had been sold “in its entirety”.

“Many projects are being crated for shipment to their new home while the flying planes are readied for cross-country trips,” the magazine said on its Facebook page. “One man’s dream has ended, but another man’s dream has just begun.”

The new owner of the collection is Steuart Walton, grandson of Walmart founder Sam Walton, according to Scramble, a publication of the Dutch Aviation Society.

Walton is the co-founder of Runway Group, a holding company with investments in northwest Arkansas; and the co-founder and president of Game Composites, a company that designs and builds small composite aircraft.

He sits on the boards of Walmart and the Smithsonian National Air and Space Museum, among other organizations, and is a licensed pilot as well as an airplane collector. His net worth has been estimated at $300 million.

Paul Allen’s estate holding company, Vulcan Inc., declined to confirm information about the sale at this time. Efforts to contact Walton or the Runway Group were unsuccessful. We’ll update this report with anything we find out.

Since Allen’s death from non-Hodgkin’s lymphoma at the age of 65 in 2018, his sister and estate trustee, Jodi Allen, has dramatically transformed Vulcan through the transfer of numerous stakes, including the space company Stratolaunch; prime property in Los Angeles and Hawaii; and Allen’s superyacht Octopus, which has played a role in the billionaire’s deep-sea exploration projects. (The new owner of the Octopus would be Swedish billionaire Roger Samuelsson.)

Vulcan also closed facilities such as the Cinerama theater in Seattle, the Living Computers Museum + Labs and the Flying Heritage Museum, largely due to the impact of the COVID-19 pandemic.

Among the gems of the Flying Heritage Collection are a British de Havilland Mosquito fighter-bomber built at the end of the Second World War; a Soviet-era Ilyushin Il-2 Shturmovik attack aircraft; a German Junkers Ju-87 Stuka dive bomber; and the White Knight carrier aircraft that helped SpaceShipOne win the $10 million X prize for private spaceflight in 2004 with Allen’s backing.
