open-in-new
<p>The SAI Quiet Supersonic Transport (QSST) was a project by <a href="/facts/Supersonic_Aerospace_International/bFu7fhoM">Supersonic Aerospace International</a> (SAI) to develop a "virtually <a href="/facts/Sonic_boom/Hfnr1Vlz">boomless</a>" commercial <a href="/facts/Supersonic_business_jet/de45u2LR">supersonic business jet</a>. The project was announced around the year 2000 and provided update announcements until 2010. After three years without any updates, the last update was in 2013. As of 2023, there have been no more updates, and the project appears to have been abandoned. The project has currently merged with <a href="/facts/NASA/TIMCV0yV">NASA</a>'s <a href="/facts/Lockheed_Martin_X-59_Quesst/kz33yXq3">X-59 Quesst</a> project. </p>
