If you have listed to supersonic boom lately, you possibly remember it. The noisy explosives sound produced by planes traveling quicker than the sound speed is startling.
Today supersonic plane doesn't fly due to supersonic boom, and one of the reasons restraining the success of Concorde, which lastly flew in 2003.
Supersonic Plane- supersonic boom
Supersonic aircraft are limited to subsonic speeds when flown over ground or near the coastline.
Nowadays, NASA is working to change those rules, turn the boom into momentum and open the way for a new generation of peaceful supersonic airlines.

Supersonic Plane- X-59
is the modern in a series of pilot aircraft, along with the X-1, which was the 1st worked aircraft in 1947 to beat the sound speed.
Lockheed Martin built and designed, under an agreement with NASA of $247.5M, the X-59 is recently experiencing ground testing.

Supersonic Plane- smooth shape
A smooth shape plays an important part in making the airplane peaceful at supersonic speeds.
The geometry of the X-59 is developed to stop shock waves from pooling. On the contrary, it unfolds with the help of tactically placed aerodynamic surfaces.

Supersonic Plane- speed
Accordingly, NASA assumes the X-59 will generate only 75 decibels of sound when flying at supersonic speed, in comparison to the Concorde's 105 decibels.
