Of course, the main drawback of supersonic aircraft is that anything that breaks the sound barrier produces a sonic boom. Since this is dangerous, many governments prohibit excessive air travel in residential areas because it can harm people and animals or damage buildings. While it is impossible to completely eliminate sonic booms, reducing their effects can make supersonic flight an attractive and feasible prospect.
One organization working on silencing sonic booms is NASA. Its X-59 Quiet SuperSonic Technology aircraft is designed to generate sonic noise instead of gunshots, by manipulating the sound waves generated by the aircraft. The simulation scale has shown reliable results, wind tunnel experiments matching theoretical predictions. NASA hopes that, in time, its research will lead to more advanced missions in the United States.
Boom Supersonic is also in the trials of its solution, the Overture aircraft, which aims to allow supersonic flight at a speed of Mach 1.7. Using the Symphony engine, the Overture is designed to be quieter than any other high-end aircraft. The company currently has many engineers working for it, including engineers who helped design jet fighters such as the F-22 and F-35.
