NASA's X-59 reaches speed and altitude milestones ahead of first quiet supersonic flights
Tomorrow NASA's X-59 reaches speed and altitude milestones ahead of first quiet supersonic flights The plane will soon be ready to fly over US communities. By Cheyenne MacDonald June 14, 2026 6:06 pm EST NASA/Lori Losey NASA's X-59 research plane took its first supersonic flight at the beginning of the month, and now it's demonstrated that it can reach the speed and altitude conditions it'll need to achieve for planned trips over US communities in the near future. The X-59 is designed to fly at supersonic speeds without producing a loud sonic boom; instead, it'll make a "quiet sonic thump," according to NASA.

Tomorrow NASA's X-59 reaches speed and altitude milestones ahead of first quiet supersonic flights The plane will soon be ready to fly over US communities. By Cheyenne MacDonald June 14, 2026 6:06 pm EST NASA/Lori Losey NASA's X-59 research plane took its first supersonic flight at the beginning of the month, and now it's demonstrated that it can reach the speed and altitude conditions it'll need to achieve for planned trips over US communities in the near future. The X-59 is designed to fly at supersonic speeds without producing a loud sonic boom; instead, it'll make a "quiet sonic thump," according to NASA. For now, though, it's flying alongside another research craft that does produce a sonic boom, to obscure whatever noise it makes as it undergoes testing.
