Seattle has a long history connected to supersonic flight and professional basketball. In December 1966, the NBA approved an expansion team for Seattle, at the same time The Boeing Company was seeking a government contract to build the nation’s first supersonic transport plane (SST). Boeing’s proposal was selected over Lockheed Martin’s by the end of that month.
Boeing had already become a major employer in Seattle through military contracts and work on the Apollo program. The SST project was expected to bring more economic growth and jobs to the region. This context likely influenced the community’s decision in February 1967 to name its new basketball team the “SuperSonics.”
Boeing engineers began developing the 2707 SST, drawing on concepts from earlier work in the 1950s. They initially focused on subsonic jets like the 707, but reports of Soviet and Anglo-French efforts pushed U.S. officials, led by the Federal Aviation Administration (FAA), to pursue their own SST project. Boeing’s design included a capacity for 350 passengers and featured a “swing-wing” mechanism intended to optimize performance at different speeds. Most of the funding came from a government contract.
In Europe, Concorde made its first flight in 1969 after Russia’s Tupolev Tu-144 flew in 1968. Rising costs forced Boeing to scale back plans for its SST and abandon some features such as swing wings. Without even a prototype completed, progress slowed.
Meanwhile, Seattle’s SuperSonics struggled early but gained support from local fans at Seattle Center Coliseum (now Climate Pledge Arena). The team posted its first winning season in 1971-72.
In spring 1971, Congress voted to withdraw all funding from Boeing’s SST project due to escalating expenses and public concerns about noise pollution from sonic booms. Without government support, Boeing ended work on the 2707.
The Sonics entered a successful period in the late ‘70s with players like Fred Brown and Lenny Wilkens leading them to an NBA championship in 1979. Success continued into the early ‘80s before changes in ownership affected team stability. Another strong era came during the ‘90s with players such as Shawn Kemp and Gary Payton performing at Key Arena.
While America’s SST program ended, Concorde operated commercial flights between cities like New York City and London starting in 1976 until it was retired in 2003 due to safety issues and high operating costs (https://www.britannica.com/technology/Concorde-aircraft).
At the start of this century, Howard Schultz bought the SuperSonics but clashed with key players including Gary Payton: “Schultz ran the Sonics more like a business than a basketball team.” In 2006, Schultz sold the franchise to Clayton Bennett of Oklahoma City; Bennett relocated it after Kevin Durant’s rookie season ended with Durant earning NBA Rookie of the Year honors.
Supersonic technology continues mainly within military aviation worldwide (https://www.lockheedmartin.com/en-us/products/x-59.html). For civilian use, NASA and Lockheed Martin are working on Quesst—a project aiming to reduce sonic boom noise—while Boom Supersonic successfully flew its prototype jet above Mach 1 speed earlier this year (https://boomsupersonic.com/news/post/xb-1-supersonic-flight-mach-1). Boom hopes passenger service will begin by 2029 but high fuel requirements and environmental concerns may limit widespread adoption.
There is ongoing interest among Seattle sports fans about reviving their NBA franchise. Samantha Holloway—former stakeholder of both Boston Celtics and owner of NHL’s Seattle Kraken—has shown interest: “As of August 2025, no announcements have been made to confirm expansion of the NBA into Seattle.”
Artifacts related to both stories remain accessible locally: The Museum of Flight displays part of Boeing’s SST mockup nose at its Restoration Center along with a British Airways Concorde open for tours; MOHAI preserves memorabilia including Seattle’s lone NBA championship trophy.
For now, both supersonic passenger travel and professional basketball await possible returns to prominence in Seattle.
