The Sonic Squeeze: NASA's Quiet Supersonic Jet Faces Its Biggest Challenge Yet The experimental X 59 supersonic jet has been making headlines for its ability to break the sound barrier without producing a sonic boom.
However, as it stands at the threshold of its most critical test phase yet – acoustic validation – we're reminded that innovation often comes with uncertainty.
NASA's Armstrong Flight Research Center in Edwards, California, has been the launchpad for the X 59's successful test flights, including its 25th flight last August.
