During Bring Kids to Work Day at NASA’s Armstrong Flight Research Center in Edwards, California, on June 17, 2025, participants pose with flight suit cutouts in front of NASA’s Quesst display. NASA's Quesst mission, which features the agency’s X-59 quiet supersonic experimental aircraft, will demonstrate technology to fly supersonic, or faster than the speed of sound, without generating loud sonic booms.

The X-59 Quiet SuperSonic Technology (QueSST) aircraft is taking shape at the Lockheed Martin Skunk Works facility in Palmdale, California. The team positioned the X-59 QueSST's nose at the front of the aircraft. As one of the more recognizable features of the X-59, the nose makes up almost a third of the aircraft length and will be essential in shaping shock waves during supersonic flight, resulting in quiet sonic thumps instead of loud sonic booms. The nose was attached and then removed from the front of the aircraft in preparation for its shipment to Fort Worth, Texas where it will undergo additional testing. The X-59 will fly at supersonic speeds above communities as part of the Low-Boom Flight Demonstration mission, during which NASA will gather community feedback to the sound of quiet supersonic flight. These findings will be shared with regulators to inform decisions on current restrictions of supersonic flight over land.
