On 26 April 1971, SR-17 Blackbird, 61-7968, flown by majors Thomas B. Estes and Dewain C. Vick, flew over 15,000 miles (24,000 km) in 10 hours and 30 minutes. This flight was awarded the 1971 Mackay Trophy for the "most meritorious flight of the year" and the 1972 Harmon Trophy for "most outstanding international achievement in the art/science of aeronautics".

The SR-71 was the world's fastest and highest-flying operational manned aircraft throughout its career. On 28 July 1976, SR-71 serial number 61-7962, piloted by then Captain Robert Helt, broke the world record: an "absolute altitude record" of 85,069 feet (25,929 m).

On 28 July 1976, SR-71 serial number 61-7958 set an absolute speed record of 1,905.81 knots (2,193.2 mph; 3,529.6 km/h), approximately Mach 3.3.

A historic speed record was set on the return trip to the United States. Capt Harold B. Adams, 31 (pilot), and Major William Machorek, 32 (reconnaissance systems operator), set a speed record from London to Los Angeles. 

On September 1, 1974 Major James V. Sullivan, 37 (pilot) and Noel F. Widdifield, 33 (reconnaissance systems officer), flashed across the starting line (radar gates in New York) at approximately 80,000 feet and speed in excess of 2,000 miles per hour. Exactly 1 hour 54 minutes and 56.4 seconds later, they had set a new world speed record from New York to London England. 

When the SR-71 was retired in 1990, one Blackbird was flown from its birthplace at United States Air Force Plant 42 in Palmdale, California, to go on exhibit at what is now the Smithsonian Institution's Steven F. Udvar-Hazy Center in Chantilly, Virginia.
