次のコンコルドのレースで「静かな」ソニックブームをテストするナサ
https://www.yahoo.com/news/nasa-test-quiet-sonic-boom-112608009.html
Nasa is set to begin test flights of a revolutionary new "low-boom" supersonic plane that could clear the way for commercial flights taking passengers between New York and London in three hours.
The space agency will start flying the X-59 next year amid a push to find a replacement for Concorde, which was retired nearly two decades ago.
Supersonic travel has been banned over the continental United States since 1973 due to the disruption sonic booms cause to people on the ground.
But Nasa, Congress, aviation regulators and private companies are now all working together to overcome the problem.
The X-59 is designed to reduce the shockwave caused by breaking the sound barrier.
It includes a very long and thin fuselage, pointed nose, and external elements placed on the top rather than bottom.
