NASA Administrator Jared Isaacman hinted at renewed high-speed flight research ambitions, sparking speculation about the SR-71 Blackbird. While denying the silhouette shown was a Blackbird, he confirmed NASA's return to "flying high and fast again." An Aviation Week report indicates NASA is working to return a Blackbird to flight after decades of retirement. The agency has approached former engineers concerning the restoration of Tail No. 844, an aircraft moved into a former Space Shuttle hangar. Crews are currently working on this aircraft. A significant obstacle is the destruction of $600 million worth of spare parts for the Blackbird fleet in 2007. This decision could lead to substantial restart costs, requiring restoration of unique fuel, ignition chemicals, and specialized fluids. Essential ground equipment, such as specialized carts for maintenance, is also no longer available. Despite these challenges, NASA management assures that engineering solutions are being developed. The feasibility of a return to flight is considered possible with sufficient resources, drawing a parallel to the Apollo missions. The specific reasons for restoring the SR-71 to flightworthy status remain undisclosed, though it could be linked to Lockheed Martin's development of the SR-72.
