Lockheed Martin designed the X-59, the world’s quietest supersonic jet

> They also learned that anything that causes discontinuity in the airplane’s shape—for instance a windshield or canopy—can add to the boom effect. This led them to get rid of the windshield altogether. Instead, the X-59 uses an external vision system, which is the only advanced technology in the plane, according to Richardson. The pilot navigates using a camera, viewing the outside through a large display. This system had to undergo rigorous certification by the Federal Aviation Administration for use in the national airspace.

That's interesting, piloting via external camera + display vs. windshield.

Concorde was loud, particularly on take-off. It always caused me to look up through the sunroof of my first car as London’s orbital road runs past the end of the runway. A few seconds of noise twice per day, that’s all.

I hope, one day, it leads to consumer benefits. And not just for the uber wealthy

Emphasis on "designed", AFAIK nothing has been delivered nor flown.
