A follow-up \"mission conditions\" flight will push the aircraft to Mach 1.4 (about 925 mph) at 55,000 feet.\n\nThe sleek jet is engineered to replace the thunderous sonic boom with a soft \"thump\" no louder than a car door closing — around 75 EPNdB, versus the 105-110 EPNdB roar of the retired Concorde. Its elongated nose and shaped airframe scatter shock waves before they reach the ground, and it has no forward windscreen at all: pilots fly using an external camera feed shown on an augmented-reality display.\n\n\"What comes next is the first time this one-of-a-kind aircraft will fly supersonic,\" said project manager Cathy Bahm. NASA plans to fly the X-59 over several U.S. cities and gather public reaction, hoping the data will persuade regulators to lift decades-old bans on supersonic flight over land and open the door to a new generation of fast commercial jets."}}
