Air Force SR-71A Blackbird Had Something To Prove In Its 'Last Operational Mission': She Went Mach 3.2 and Did LA to DC in 64 Minutes

On March 6, 1990, two U.S. Air Force lieutenant colonels—Ed Yielding and Joseph Vida—flew the SR-71A Blackbird on its final operational mission, marking a farewell that still proved the aircraft’s unmatched performance. Departing from California for Washington, D.C., the jet covered 2,299.7 miles in 64 minutes and 20 seconds, averaging 2,144.8 mph, roughly Mach 3.2 throughout. The flight set multiple speed records recognized by the National Aeronautics Association and the Fédération Aéronautique Internationale, including a coast-to-coast run in 67 minutes and 54 seconds. The SR-71’s enduring 1976 absolute benchmarks for speed and altitude—2,193.2 mph and 85,069 feet—have stood for 50 years.
