Official Unveiling Coming For X-59 QueSST This Month The last we heard about the Lockheed Martin/NASA QueSST X-59 was perhaps mid-2023 when they were ground-testing the first assembled test aircraft prototype. https://www.jetforums.net/threads/news-nasa-x-59-moves-towards-ground-testing.4687/#post-29152 . We were able to see parts of the airframe last year but not a fully-assembled aircraft. This month NASA is expected to officially roll-out the X-59. Although the aircraft was expected to fly last year, it has been pushed back to October, 2024.
