NASA has achieved a significant milestone in its effort to make supersonic passenger jet travel over land a real possibility by completing the preliminary design review (PDR) of its Quiet Supersonic Transport or QueSST aircraft design. QueSST is the initial design stage of NASA's planned Low Boom Flight Demonstration (LBFD) experimental airplane, otherwise known as an X-plane.
