A sonic boom is dangerous to both life and property (it can damage ears and break glass on buildings). As a result, this plane would be completely obsolete if it flew over land masses only. It would have to be used as a trans-Pacific/Atlantic plane.
The answer is: Fly higher and you won’t hear the sonic booms.
But I do believe Boeing is currently developing such an aircraft, I’ve seen them mentioned it on Instagram. I think they also mentioned one thing they emphasise is quietness but I don’t know whether are they referring to the sonic booms or cabin noise.
One of the reasons why the Concorde wasn’t successful is because it used too much fuel hence expensive to run. What I was trying to say if the supersonic plane has good numbers in terms of fuel efficiency then it would be successful considering the high fuel prices currently.
The world is too small for things that fast… They would basically get up to 90,000 and have to start descending right after that. This seems like something better suited for space travel… Also RIP the ozone layer if that thing is gonna punch through it 3000 times a day…
