The X-59, a long-nosed demonstrator designed to help develop the tech required for “quiet” supersonic flight, notched the milestone on Friday (June 5), more than six months after getting off the ground for the first time. “The X-59’s first supersonic flight is a testament to America’s enduring leadership in science, engineering and aerospace innovation,” Michael Kratsios, assistant to the president for science and technology and director of the U.S. Office of Science and Technology Policy.X-59 team members won’t rest on their laurels, however. In just a few days, they plan to send the plane on its first “mission conditions” flight one that reaches a top speed of Mach 1.4 and an altitude of about 55,000 feet (16,764 m). IS America still leading in science , engineering and aerospace ?
