Yes, but if the experiment _succeeds_, then the technology could be used
to make an airplane that can fly as fast as the Concorde over the oceans,
and faster than the speed of sound, without sonic booms, over land...
which is also big enough for passengers.

Reason the Concord was scrapped because the accident, also the company was not making money.
Sonic boom was just a nuisance, people complained about!

More than a nuisance. Sonic booms are ecologically harmful, and the
Concorde engines very inefficient and contributors to carbon
pollution.

No, there aren't other noises in cities that *break things*.

I don't think that is true at all.

We get the odd sonic boom here when UK launches supersonic interceptors
to greet Russian incursions and they shatter a few windows (although
anyone with a dodgy cracked window also makes a claim). They typically
go supersonic once over the sea but the Mach cone touches down on land.

The last really big one over land was an over enthusiastic Swiss pilot
who shook buildings with minor earthquake equivalent force.

https://www.independent.co.uk/news/uk/home-news/mystery-sonic-boom-caused-by-swiss-fighter-jet-b1960744.html

It made the national news.
