NASA explores returning historic SR-71 Blackbird to flight

NASA is reportedly exploring the possibility of returning a historic SR-71 Blackbird to flight after nearly three decades of retirement. The aircraft in question, tail number 844, was recently moved from its outdoor display at the Armstrong Flight Research Center at Edwards Air Force Base in California into a hangar.

While NASA Administrator Jared Isaacman has not officially confirmed a formal return-to-flight program, he recently signaled the agency’s intent to return to “flying high and fast again” by discussing the rebuilding of NASA’s X-plane portfolio. Reports indicate that the agency has approached former SR-71 engineers to assist with the potential effort.

Restoring the 59-year-old aircraft presents significant technical and logistical challenges. A major obstacle is the lack of available parts, as a $600 million supply of spares was reportedly destroyed in 2007. Additionally, NASA would need to secure access to specialized materials, including the unique JP-7 fuel blend, triethylborane ignition chemicals, and bespoke ground support equipment that is no longer in production.
