Following years of research and design engineering, NASA believes it has come up with a solution on how to reduce a sonic boom. The agency has been working with defense contractor Lockheed Martin to develop the technology that can overcome current noise restrictions for commercial supersonic flight over land and pave the way for establishing a new market of air travel. The project is known as X-59 Quiet Supersonic Technology or QueSST and, according to NASA, it is already taking shape – with assembly work ramping up towards the eventual first flight of the supersonic jet scheduled in 2021.
