NASA plans to fly its 'quiet' supersonic jets within 3 years
NASA has revealed that it plans to fly the X-59 Quiet Supersonic Technology (QueSST) aircraft within three years. Cruising at 55,000 feet at a speed of around 1500 kmph, the X-59 is said to create a sound far quieter than a regular sonic boom. "We can't wait to see this bird fly!" NASA chief Jim Bridenstine said.
