Supersonic Flight
NASA’s X-59 experimental aircraft is preparing for its second flight, a step that will set the pace for more flight testing in 2026.  Over the coming months, NASA will take the quiet supersonic jet faster and higher, while validating safety and performance, a process known as envelope expansion.  NASA test pilot Jim “Clue” Less will be at the X-59’

High-Speed Flight
What We do The High-Speed Flight (HSF) project develops technologies that make high-speed, airbreathing, commercial flight possible from Mach 1 to Mach 5 and above. HSF creates tools, technologies, and knowledge that will help eliminate today’s technical barriers to practical supersonic flight, most notably sonic boom.
