A New Design of Aerodynamic Elegance According to NASA and Lockheed, they went back to the basics of aerodynamics to design an aircraft that flies faster than the speed of sound as quietly as possible.  They say the X-59 is a combination of highly advanced technology and elegant simplicity.  It is still under development.
