In an interview with The War Zone (TWZ), former NASA lead propulsion engineer Tim Conners discusses the possibility of returning the SR-71 Blackbird to the air.
Conners, who served as the lead propulsion engineer for NASA’s Blackbird program in the 1990s, provided his analysis following a series of events suggesting a renewed interest in the jet. These include the disappearance of Tail 844—an SR-71A that was removed from public display at the Neil Armstrong Flight Research Center at Edwards Air Force Base—and reports that NASA has been contacting former SR-71 personnel about returning to work on the aircraft. Aviation Week editor Steve Trimble reported the aircraft’s absence on Sept. 24, noting that satellite imagery showed Tail 844 had been missing since at least May.
Jared Isaacman Displays Rendering of Dark Aircraft
The speculation surrounding the aircraft follows a presentation by NASA Administrator Jared Isaacman titled “Rebuilding our X-plane portfolio.” During the keynote, Isaacman displayed a rendering of a dark aircraft emerging from clouds with a silhouette that drew immediate comparisons to the Blackbird. When asked if the aircraft was an SR-71, Isaacman cryptically responded, “You sure that’s a Blackbird?”
Isaacman has called for a review of aeronautics investments to include more radical engine and airframe designs for national security, commercial, or civil needs. He stated that NASA will soon be flying as fast and high as it has in decades past, and potentially even faster. In a May 2026 directive, Isaacman sought additional X-planes and urged the agency to avoid funding projects that industry has a clear incentive to finance. He criticized using the aeronautics budget for incremental efficiency gains on 40-year-old engines.
Isaacman described the X-59 as the start of this renewed push into experimental flight. Developed with Lockheed Martin Skunk Works for the Quesst mission, the X-59 is designed to gather data for future overland supersonic travel rules by demonstrating quieter supersonic flight. The aircraft first flew in October 2025 and reached approximately Mach 1.1 and 43,400 feet during its first supersonic flight on June 5, 2026.
Technical Hurdles to Flight
Despite the feasibility argued by Conners, other engineers have highlighted significant obstacles to returning a dormant Blackbird to the skies. According to reports in Task & Purpose, virtually no SR-71 parts are currently in production, and the final remaining stock of spare parts was destroyed in 2007.
Returning the aircraft to flight would require NASA to reinvent or source a new supply of specialized components, ranging from obscure engine parts to the aircraft’s specific JP-7 fuel. While a NASA spokesperson acknowledged the rumors regarding the SR-71, the agency has not confirmed any official plans for the aircraft.
Engineers Sought to Help Restore Lockheed Aircraft
The U.S. government is seeking engineers to help restore the former NASA-operated Lockheed SR-71A after nearly 27 years.
While the Blackbird has been dormant, its titanium airframe is resilient to the oppressive heat of the California desert. The structure was built to withstand atmospheric friction temperatures exceeding 500 degrees Fahrenheit while flying at 2,000 miles per hour.
