NASA has pushed back the first flight of its X-59 Quesst supersonic demonstrator aircraft to next year as it works through “several technical challenges identified over the course of 2023,” the agency announced late last week.

The Mach 1.4 X-59 will be used to gather data on public response to a softer thud—rather than a sonic boom—that may be possible with modern supersonic aircraft. This data could pave the way for the eventual return of supersonic flight over land.
